1. Extreme-Environment Safety Switch Overview
The Schmersal A-K4P-M12P-S-G-5M-BK-2-X-T-4 is a high-performance magnetic safety switch engineered for critical industrial applications requiring uncompromising reliability. Featuring a stainless steel housing (S suffix) with IP69K protection, this device utilizes non-contact magnetic sensing to monitor guard positions without mechanical wear. The "K4P" designation indicates 4-pin M12 connector (P-coded), while "G" confirms 24V DC operation with 5-meter PUR cable (5M). Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, its BK-2 black coating provides enhanced corrosion resistance against chemicals, salt spray, and UV degradation. Operating across -40°C to +100°C (T-4 rating), it integrates dual-color diagnostic LEDs (X suffix) and force-guided contacts for safety-critical machinery in offshore, chemical processing, and high-temperature industrial environments.
