SIPHA S21 HEAD AND ACTUATOR LONG 3M CABLE 4 WIRE 1 NC 1NO

The ALLEN-BRADLEY 440N-S32015 is a non-contact safety switch that provides 9mm sensing distance with both normally open and normally closed reed contacts. Designed as a Sipha-style switch with a standard actuator, it offers contact redundancy for machine safety and straightforward integration into guarding systems. The plastic housing with a 3 m PVC cable simplifies installation in production lines where a compact, low-profile sensor is required. Use this non-contact switch for monitoring guards, doors, or hinged covers where reliable sensing at short range and clear N.O./N.C. outputs are needed for safety interlocks and control circuits.
