It uses a coded magnet actuator (sold separately) to detect guard position without mechanical wear — the Hall Effect sensor reads the magnet field through the housing, so there are no plungers or levers to gum up in dusty or vibrating environments. The safety contacts are 2 NC + 1 NO, which means two normally-closed channels wired in series for the safety circuit (redundant, fault-tolerant per ISO 13849-1) and one normally-open auxiliary channel for the PLC status input. The IP67 rating and polyester body mean it shrugs off washdown and airborne grit — built for the pit, mill, or food line. The LED indicator (Yes) gives a quick visual on actuator alignment and switch state — green when the guard is closed and the magnet is within range, off when open. That saves a multimeter trip on commissioning or when troubleshooting a guard-open fault. The M12 connector is a standard 4- or 5-pin quick-disconnect; pre-wire a cordset and swap a failed switch in minutes without re-terminating. The polyester switch construction resists corrosion from coolants, oils, and mild acids — not rated for full chemical immersion, but it handles splash and vapor in machining or processing areas.","metaTitle":"D40P-SPC-21-M12 Hall Effect Safety Interlock, 2NC+1NO, IP67","metaDescription":"D40P-SPC-21-M12 non-contact Hall Effect safety interlock switch. 2 NC + 1 NO safety contacts, IP67, M12 connector.

The D40P-SPC-21 (without the -M12 suffix) uses a fixed cable instead of a connector. The electrical and safety specs are identical; the choice depends on whether you prefer a hardwired pigtail or a quick-disconnect cordset for easier replacement."},{"question":"What compliance documentation is available for D40P-SPC-21-M12?","answer":"The evidence does not list specific compliance certifications (UL, CE, RoHS, REACH) for this order code.
