RTH or STH - Contacts in Housing
The standard grounding for most Johnstech contactors utilize contacts, either S-shaped (STH) or ROLâ„¢ shaped (RTH) contacts configured in the Torlon housing directly beneath the center of the device package ground pad. Johnstech self-cleaning wipe technology provides improved MTBA (mean time between assists) and lower ground inductance.

Insert Technologies
In addition to ground contacts in the contactor housing, Johnstech offers ground inserts that can be removed from the contactor housing itself and interchanged as application requirements change. These ground inserts are used for both grounding and thermal requirements.
RCI or SCI - Contacts in Copper Insert
This insert configuration utilizes multiple contacts in a metal insert to meet the low ground inductance and thermal requirements of the most demanding applications. Available with either S contacts (SCI) or with ROLâ„¢ contacts (RCI).

Other Grounding Options
Other grounding options are available upon request.
