The mechanical active principle with positive opening means the NC contact is forced open by the actuator — it does not rely on spring return, so a welded or stuck contact cannot mask a closed signal. That is the safety-relevant feature: positive opening is required for interlock circuits guarding access to hazardous motion per IEC 60947-5-1. The roller plunger actuator suits linear cam tracks or sliding doors where the cam rolls over the plunger rather than striking it. ## IP65 and the enclosure The housing conforms to EN 50047, a standard 50 mm wide block form factor that mounts directly with screw fixing onto machine frames or profile rails. No DIN rail clip; plan for two M4 screws through the mounting slots. ## AS-i connection and contact configuration Connection to the AS-i bus is via insulation displacement method — a piercing contact that terminates the yellow AS-i flat cable without stripping. The switch carries one NC contact and no NO contacts, so it is a single-channel safety input: one normally-closed positive-opening path into the AS-i safety monitor.","metaTitle":"Siemens 3SF3210-0DV00-0BA2 Communication-Capable Position Sw","metaDescription":"Siemens 3SF3210-0DV00-0BA2 communication-capable position switch with AS-i adapter, IP65, positive opening 1NC, roller plunger, block housing EN 50047.
