Contact versions
The ERmetTM 2mm H.M. Connector System. offers 15 standard contact lengths that utilize the proven pressfit assembly technique. Within the 15 contact lengths are 3 mating levels, achievable on both the plug-in and rear I/O side. Note you always keep 1.5 mm spacing between levels, for enhanced sequential mating.
On the plug-in side, the 3 contact levels are: 8.2 mm, 9.7 mm and 11.2 mm. On the rear I/O side there are 5 pressfit terminal length options: P1,P2, R1, R2, and R3. The P1 and P2 terminal lengths are for standard backplane applications with terminal lengths of 3.7 mm and 4.5 mm respectively. The R1, R2 and R3 terminal lengths are for rear I/O applications, with lengths of 13.0 mm, 14.5 mm and 16.0 mm respectively.
The optimum terminal length is determined by the printed circuit board thickness, rear shroud height and the desired mating level.
