The molded-plastic enclosure carries an IP65 rating, so the switch body and the AS-i connection point withstand washdown and dust ingress on a conveyor line or packaging machine. The switching function is positive opening — the NC contacts are mechanically forced open when the roller lever is actuated, regardless of weld or spring failure. This meets the safety-circuit requirement for a positively driven NC contact per IEC 60947-5-1, making it suitable for guard-door interlocking or end-of-travel limit positions where a fail-safe signal is mandatory. The actuator is a roller lever, and the actuator head follows EN 50047 design E — a standard 31 mm wide block that mounts via screw fixing. The AS-i connection uses the insulation displacement method, so the bus drop is made by pressing the flat cable into the slot; no separate bus coupler or terminal block is needed at the switch. ## Contact configuration and switching behaviour The auxiliary contact block provides 2 NC contacts and 0 NO contacts. For a safety circuit that needs two-channel feedback from a single actuator position — e.g., one NC to the safety relay and one NC to the PLC input — this switch delivers it without an add-on contact block. The snap-action mechanism gives a defined switching point and contact speed independent of the actuation speed, which avoids chattering on slow-moving cams or worn rollers. ## Environmental range and deployment context The IP65 rating means the switch body and the AS-i connection point resist hose-directed water and dust ingress — suitable for washdown areas in food processing or wet machining lines.","metaTitle":"Siemens 3SF3200-8EV00-0BA1 Position Switch, AS-i, 2NC, IP65","metaDescription":"Siemens 3SF3200-8EV00-0BA1 position switch with AS-i adapter, 2NC snap-action, roller lever, IP65, molded plastic.
