, Telemecanique has introduced two safety
switches that operate when the hinge of the guard door swings by as
little as five degrees. The compact XCS-PR provides two output contacts,
while the XCS-TR provides three; both are compatible with industry
standard mountings, so they easily replace older types of switch. The
units feature double-insulated construction and IP67 environmental
protection. XCS-PR switches have a single cable entry, while XCS-TR
models have two. In each case, the cable entries can be PG11, M16 or
1/2in NPT. The switch contacts are slow-break types with positive action,
and are positively driven by the actuator spindle.
