Erni's DIN 41612 connector family comprises 25 basic sizes and has many complementary versions.
Developed for use in 19" rack systems in accordance with DIN 41494, the large number of different sizes and techniques make it possible to use these connectors for a wide range of applications such as: connection between plug-in card and back-panel wiring; connection between PCBs arranged one above the other; connection to peripheral equipment with connector housings as accessories; as periphery connectors for external interfaces from the wiring side.
Special features
For connectors size B, C, Q, R, P, D, E and F, 0,8 mm early make/last break male contacts can be loaded in any position in rows a, b, c, d, e and z. The early make/last break contacts of the high current connectors of size H11 and H15 have a length of 3,5 mm (1,5 mm on request).
For applications with early make-last break contacts male connector insulators with pre-centering ensures even more reliable mating. The insulators of the female connectors are recessed at the appropriate position/s. Their dimensions do not conform to DIN 41612.
Various coding systems are available:
* Integrated coding with coding wedges. In this case coding wedges are fitted to the female connectors and the male connectors are provided with corresponding recesses.
* Integrated coding with coding pins. Here coding pins are inserted into the female connectors and holes are drilled in the male connectors in the relevant coding positions;
* Coding with coding strips. The coding strips are mounted onto and in effect, become part of the connectors. No extra modular space is required in the 19" rack system.
Retention clips and wiring accessories
For efficient mounting of the right angle connectors a retention clip can be installed on the connector by Erni. The connectors are attached to the PCB with retaining clips that lock into drill holes on the board eliminating the need for bolts and nuts - maximum PCB thickness 1,6 mm. Since the clips can also be soldered, plated-through PCB holes are recommended for such applications.
Erni has a connector housing range that, together with the interface connector system, offers optimum protection for all plug-in interfaces for DIN 41612 connectors. The range is dimensioned for the 19" rack system. Suitable variants are available for virtually every type of connector. Whether one intends to use a short type B/2 connector or a 64-pin insulation displacement connector, Erni can supply a suitable housing.
The connector housings are suitable for a maximum of three cable outlets and are fitted with strain-relief clamps. For plug-in interfaces on the front or back panel of the rack, Erni has developed guide elements and guide frames in collaboration with well-known users. These elements permit exact guidance for correct mating and provide robust screw locking. In addition, coding device/s may be fitted.
Approval certificates are UL, VG, and CSA.
