1. Compact Hazardous-Area Safety Switch Overview
The Schmersal A-K3P-M12-S-G-2M-GY-1-X-A-4 is an ATEX/IECEx-certified magnetic safety switch engineered for Zone 21/22 hazardous environments. Featuring a stainless steel housing (S suffix) with IP69K protection, this compact device utilizes non-contact magnetic sensing within a 60×40×25mm footprint. The "K3P" designation indicates a 3-pin M12 connector (P-coded), while "G" confirms 24V DC operation via a 2-meter PUR cable (2M) in gray (GY-1) for UV resistance. Certified for ATEX/IECEx Zone 21 (A-4 suffix), it operates from -25°C to +70°C with dual-color diagnostic LEDs (X suffix). SIL 3/PL e compliant force-guided contacts ensure failsafe guard monitoring in explosive dust atmospheres found in chemical processing, grain silos, and pharmaceutical powder handling applications where standard switches are prohibited.
