It uses a mechanical active principle with a roller plunger actuator and a positive-opening NC contact — the NC opens mechanically even if the contacts weld, which is the safety-relevant behavior required for interlock circuits on guards and access doors. The housing is a molded-plastic block design per EN 50047, fastened with screws, and rated IP65. That means it's dust-tight and protected against water jets — suitable for washdown areas in food processing or packaging lines where you need to hose down the machine perimeter without pulling the switch. ## AS-i connection and wiring Electrical connection is via the AS-i insulation displacement method — the flat cable pierces into the switch body, no separate T-piece or M12 drop cable required. This keeps the wiring count low on a long AS-i segment and simplifies panel layout when the switch is mounted directly on a machine frame rather than inside a control cabinet. The switch carries one NC auxiliary contact and no NO contacts. For a safety circuit that needs a positively-guided NC to signal 'guard closed', that's the only contact you need; the AS-i adapter handles the communication back to the safety monitor. ## Environmental range and deployment The molded-plastic enclosure handles the temperature swing without condensation issues inside the switch body.","metaTitle":"Siemens 3SF3210-1DV00-0BA2 Position Switch, AS-i, IP65, 1NC","metaDescription":"Siemens 3SF3210-1DV00-0BA2 communication-capable position switch with AS-i adapter, IP65, roller plunger, positive opening 1NC.
