The Siemens 3SF3210-0GV00-0BA2 is a communication-capable position switch with an integrated AS-i adapter, designed for direct connection to an AS-interface network without a separate I/O block. Its block housing conforms to EN 50047, and the twist lever actuator is field-adjustable for approach direction. The single NC contact is mechanically positive opening per IEC 60947-5-1, meaning the normally-closed circuit breaks even if the contacts weld — a requirement for safety-related limit switching in guarding circuits.
Mounts via screw fixing to machine frames or brackets. The molded-plastic housing carries an IP65 rating, so the switch body and actuator withstand direct hose-down and dust ingress — suitable for washdown zones in food processing or packaging lines. The AS-i connection uses the insulation displacement method (piercing the flat cable), which eliminates separate wiring to a remote I/O node and reduces panel fill.
Rated for ambient operation from -25 °C to +60 °C, covering most factory-floor environments without derating. The single NC contact (no NO contacts) is typical for safety interlock applications where the switch monitors guard position and breaks the safety chain on opening. The twist lever actuator allows 10° to 10° angular adjustment, giving flexibility in cam or ramp approach angles.
