The MicroStac connector series is a hermaphroditic design. The connector and the counter connector are identical, and the typical subdivisions of male- and female-multipoint connectors are omitted. Nevertheless, ERNI discovered a way to implement two contact points (similar to double female contact). The design calls for fast, fully automatic SMT assembly. We use the tilt-proof contact principle by way of dual-side positioning of the contact on the circuit board. In addition, we use the very low weight, as well as the insulator body-integrated grip surface, for the vacuum pipette and the tape-and-reel packaging.

The new MicroSpeed SMT Connector, for fast data transmission, was designed especially for board-to-board connections in telecommunications and datatransmission devices. This new modular connector system is the right solution for next-generation systems with transfer rates of up to 10 Gbits/sec. For differential-data transmission several different signal-pair arrangements are possible. Parallel signal connections are recommended for improved crosstalk properties. We achieve exceptional signal integrity by the design which features two signal and two shield contact rows. SPICE models are available. Evaluation boards also can be borrowed or purchased.

The SMC line of versatile connectors offers a great deal of design application flexibility. Different modules (such as the MiniBridge, straight and angled male and female multipin connectors) in combination with other options (e.g. IDC versions) afford users the freedom for an optimal assembly design. The connectors are reliably produced on state-of-the-art, fully automatic manufacturing machines. Due to the high contact density and small space required, SMC connectors offer a number of new application possibilities. The precision manufactured contact guarantee a reliable mate. SMC connectors are available in several different heights. The combination of standard profile and low male and female connectors support four different board-to-board stacking heights (8.0 - 14.0mm).

ERNI's ERmet line of connectors offers incomparable performance and flexibility for today's system designs. With constant technical advancements and expansions, this series of connectors supports any possible arrangement of circuit boards, such as board-to-backplane and board-to-board. ERNI's complete product offering includes right angle females, with and without shrouds, vertical males, available 15 different contact lengths, vertical females, right angle males, power connectors, shrouds, coding kezs and cable assemblies. ERmet connectors are popular and well received around the world. They are primarily used in telecom- and in network-systems. IEC standardization ensures compatibility between manufacturers. The ERmet product line also is being used increasingly in industrial computers (IPCs), where PIGMG specifications apply.

ERmet ZD connectors were specially developed for differential high-speed signal transmission in telecom applications with data rates of up to 10Gbits/sec.
This robust, high quality modular connector system is just as well-suited for use in conjunction with the 2mm HM (IED 61076-4-101) ERmet line of connectors.
The inline design of the signal and ground contacts makes simple, economic routing (conductor track routing) possible. Signal and ground contacts have different connection levels with a gap of 1.5mm, thus ensuring a safe connection. In addition, the contacts are assembled into a robust housing.
The ERmet ZD connector utilizes an optimal grid construction that reduces signal interference and offers ample room for conductor track routing. Its optimized design and effective shielding allow the ERmet ZD system to exhibit superb performance when it comes to crosstalk and reflections.
The ERmet ZD connector has been selected as the backplane interconnect for the PICMG 3.x (ATCA) industry standard.

This high speed backplane connector system was specially developed to meet the electrical requirements in designs with differential, low-voltage signals and high data rates. ERmet zeroXT has a very low Crosstalk level, minimal skew, good routing properties (simple conductor track routing), a reliable dual beam female contact design, different contact levels, and a robust housing. The optimized contact grid (2.5mm) allows for effective and flexible routing. Every differential signal pair is closely coupled with the ground signals to ensure a controlled impedance. Each wafer is enclosed by a shield plate. In addition, all differential signal pairs on the male connector are shielded again by C-shaped shields.

The alignment modules were developed to securely connect the daughter card to the backplane. The modules also offer integrated support for HM coding pieces. Coding at the connector is no longer required, and more signal contacts are available as a result. For an even more stable and “capacitive” coding, there are guide pins designed that match the hole in the counterpiece. This provides an additional eight different codings, such as an octagonal version. Another auxiliary function is the version featuring an electrical contact. The gold-plated contact surfaces make for low-resistance shielding, and for transmitting current over a large cross section with up to 40 A at 20 °C.

The DIN 41612/IEC 60603-2 connector line from ERNI includes standard connectors and customer-specific connector technology solutions. The standard and inverted connectors for printed circuits correspond to national and international standards. All connectors have the same installation requirements, regardless of differing application characteristics. This connector line includes modules with a high contact density for low voltages; and modules with a low contact density for high voltages. In addition to the standard types, ERNI offers a wide variety of versions and connection technologies that provide users with economical solutions.

ERNI LPV connectors (Latch Headers), in compliance with IEC 60603-13 (DIN 41651), are well known to our customers worldwide. These connectors were installed in large number for interfacing hard disk drives (HDDs) to processor boards about 10 years ago. Miniaturization has created increasingly popular “low profile” versions (e.g. for embedded systems featuring the PC104 or PC104 plus standard). The international standard specifies a soldered pin connector for circuit boards. Meanwhile, other termination types have become established, too. The female connector is designed to be used to connect a ribbon cable using IDC technology. Integrated coding at the center of the insulating housing eliminates contact damage caused by improper mating. Optional locking latches secure the connection against inadvertent release due to vibration or shock. The male connectors can be obtained as a pressfit, wave soldering or THR connection system.

ERNI pin connectors are one- and two-row plastic strips assembled with square 0.6 x 0.6mm pins. The connector side is completely gold-plated, and the terminal side is tin-plated. Unshrouded headers are available in different connection lengths and termination types. Right-angle versions are also available.
Single and dual row connectors can easily be broken off to the desired number of pins that is required, by using predetermined break points. Any number of pin connectors can be arranged next to each other in a row, as the housings have detents on their long sides. ERNI supplies many customer-specific solutions of this kind. It is also possible to have unshrouded headers with a pressfit zone on both sides - an inexpensive board-to-board connection.

The majority of components connected to a backplane are connected using solderless pressfit technology. Two-row power taps featuring either an elastic pressfit zone or soldering termination were developed by ERNI for connecting power supply lines. Cable plugs or terminal sockets can be optionally used for cable termination.
The power taps can either be connected via screw or plug-type terminals with cable lugs or flat terminal sockets. For versions featuring 6 pressfit pins, the max. current is 30A at 20°C ambient temperature. Versions featuring 10 pins can withstand 40A at 20°C.

D-Sub series, TMC connectors, are primarily used as interface connectors. With five different pin counts and various termination types available, these connectors are found in almost all applications. ERNI has a comprehensive line of accessories for D-Sub connectors. Whether for easy assembly, different connection types, EMC, or interlocks, you will find innovative solutions from ERNI. Today's printed circuit board designs demand flexible and economic connector concepts. For our customers, this means availability of complete series, with all connection technologies, at an attractive price. For ERNI, this means the modularization of connector concepts, from design through manufacture. The new D-Sub generation has been designed on this basis. They are available in male and female with different termination types, both straight and right angled. This new generation is fully RoHS-compliant.

Modular jack connectors, a cornerstone of communications technology, have been used in the telecommunications and ethernet industry for many years. The main reasons for this are the simplicity and reliability of these products. Whether integrated in a simple telephone system, or in a gigabit application, “mod. jacks” represent the standard for network connections. Mod. jacks can be obtained in many different versions. Increasing data rates and space-saving requirements are driving increasing requests for these connectors with integrated filter components.

For different ERbic bus systems, the interface connectors combine compact dimensions with horizontal or vertical cable termination. The color coding describes different bus systems, nodes, and termination versions with integrated termination resistors. The integrated switch of ERbic switch versions allows for the flexible configuration of Profibus systems. The switch switches the termination on and off, and can be externally operated. The MAX housing is made from die-cast metal and is ideal for use in rough environmental conditions, and for meeting EMC requirements. The MAX housing is also equipped with an axial cable output in the connecting direction, and therefore, has a slimline shape.

ERNI M8/M12 circular connectors can be used to implement a flexible I/O or field bus connection on the circuit board. With the modular design concept, connectors can be quickly and easily manufactured in different heights and versions, e.g. 2-, 3-, 4- and 5- pin M12 connectors as well as 3- and 4-pin M8 connectors. We use a variety of SMT, pressfit or THR technology, depending on the customer's requirements. M12 connectors are currently recommended as field bus connectors for almost all field bus specifications, and are also available with coding. The introduction of the new M8/M12 connectors illustrates ERNI's commitment to develop a reliable and flexible I/O or field bus connection on the circuit board.

ERNI offers three different types of connector housing for the Series D-Sub connectors acc. to DIN 41 652 and MIL C-24308: KSG 200, fully insulated housing with inner shielding plates; KSG 185, a housing with snap-in latches and/or screw locking & integrated coding; KSG 183, a housing with snap-in latches.
