This is a manual of the CHM 2.0 connector system. The connector system is developed according to the international standard IEC 61076-4-101. It provides multi-contact plug-and-socket connectors for customers, which ensure that PCBs can be exchanged from system to system without problems. At the same time, important parameters such as fixing, shielding and coding remain compatible with all applications.
The manual describes the CHM 2.0 hard‑metric connector system developed to meet IEC 61076‑4‑101. It explains the modular design, stacking method, coding keys, and the various connector types (A, B, C, L, M, N, Compact PCI) with their dimensions and contact options.
Technical data such as spacing, temperature range, mechanical durability, contact materials, and electrical test voltages are provided, along with assembly drawings, part numbers, and contact‑length options for front and rear mating areas.
| Mechanical durability (class 1) | > 500 mating cycles |
|---|---|
| Mechanical durability (class 2) | > 250 mating cycles |
| Contact coating | Au over PdNi over Ni |
| Maximum contact force | 0.75 N |
| Insertion force per pin (shield) | 1 N |
| Extraction force per pin (shield) | 0.15 N |
Performance class 1 guarantees more than 500 mating cycles.
