It carries a single normally-closed (NC) contact with positive opening operation — meaning the NC contact is mechanically forced open when the actuator is tripped, regardless of weld or spring failure. That makes it a safety-rated switching element for guarding applications where a positively driven break is required per IEC 60947-5-1. The housing is a metal block design per EN 50041, painted, with screw fixing and an angular roller lever actuator. Connection is via AS-i insulation displacement method, which pierces the AS-i flat cable without stripping — a time-saver during panel or machine wiring. The switch is 56 mm wide, matching the EN 50041 block footprint common on European machine safety circuits. For a maintenance or spares purchaser, this means the part is still a standard catalog item. If you are holding a BOM line for a legacy machine that uses AS-i safety switches, this is the direct drop-in replacement without rewiring or adapter plates. The single NC contact (1NC, zero NO) is deliberate: this switch is intended to be wired into the safety chain as a normally-closed input to a safety PLC or AS-i safety monitor. The angular roller lever actuator gives a 90° approach angle, common for cam-operated guard doors or hinged access panels. The metal housing and painted coating hold up in industrial environments where plastic switches might crack under impact or chemical exposure.","metaTitle":"Siemens 3SF3100-0FV00-0BA2 Position Switch, AS-i, 1NC, IP65","metaDescription":"Siemens 3SF3100-0FV00-0BA2 communication-capable position switch with AS-i adapter, 1NC, positive opening, IP65, metal housing.
