It carries a positive-opening NC contact — that means the normally-closed circuit physically breaks when the actuator is tripped, no spring reliance, which is what safety circuits demand. The housing is a metal block per EN 50041, painted, sealed to IP65, so it stands up to washdown and the dust and moisture you find out on a conveyor line or packaging machine. The AS-i connection uses the insulation displacement method — no screw terminals on the bus side, just push the AS-i flat cable into the adapter and it pierces the insulation. That saves wiring time but means you need the correct AS-i cable profile; standard round cable won't work here. The twist lever actuator gives you a roller at the end, so it tracks cam profiles on rotating machinery without wearing a flat spot. One NC contact, zero NO contacts — that's a single-channel safety input or a dedicated stop signal. If your circuit needs a separate status feedback contact (NO), you'll need to add an auxiliary block or pick a variant with more contacts. The positive-opening function means this NC is suitable for safety-related applications up to the limit of a single mechanical contact, typically PL c or SIL 2 depending on the architecture. Fastening is screw fixing through the EN 50041 block holes, so it bolts directly to machine frames or standard mounting brackets.","metaTitle":"Siemens 3SF3100-1GW00-0BA2 Position Switch, AS-i, IP65, 1NC","metaDescription":"Siemens 3SF3100-1GW00-0BA2 communication-capable position switch with AS-i adapter, IP65 metal housing, positive opening 1NC contact.
