It uses a mechanical plunger actuator with positive opening operation (the NC contact is forced open even if the plunger welds), which is the safety-critical requirement for guard door monitoring and interlock circuits per IEC 60947-5-1. Rated IP65, the molded-plastic block housing (EN 50047 profile, 50 mm width) withstands washdown and dust ingress on packaging lines, conveyor transfer stations, or machine guarding zones. The rounded plunger has a 6 mm diameter and overtravel capability, giving it tolerance for misalignment in the actuator cam. The single NC contact (1 NC, 0 NO) is the standard fail-safe configuration for safety circuits — the positive opening mechanism ensures the normally-closed path opens reliably when the plunger is depressed. ## AS-i wiring and panel integration Connection is via AS-i insulation displacement method (piercing the flat cable) — no screw terminals, no separate power supply wiring for the switch. The AS-i bus carries both power and data to the switch, which is addressed via the master. This cuts wiring time on a line with multiple position switches: one two-wire cable daisy-chains power and signal. Screw fixing to the machine frame or bracket. The block form factor (EN 50047) means it swaps into the same cutout as other standard limit switches in that footprint — no panel modification needed if replacing an older unit.","metaTitle":"3SF3210-0CV00-0BA2 AS-i Position Switch, 1NC, IP65, EN 50047","metaDescription":"3SF3210-0CV00-0BA2 communication-capable position switch with AS-i adapter, 1NC positive opening, IP65, EN 50047 block housing.
