1. Product Overview
The Schmersal A-K4P-M12-S-G-5M-BK-1-X-A-4 is an industrial safety switch engineered for hazardous environments requiring robust performance. Featuring a stainless steel housing (S suffix) with IP67 protection, this device utilizes non-contact magnetic sensing for guard position monitoring. The "K4P" designation indicates a 4-pin M12 connector (P-coded), while "G" confirms 24V DC operation via a 5-meter PUR cable (5M) in black (BK-1). Certified for ATEX/IECEx Zone 21 (A-4 suffix), it operates across -25°C to +70°C with dual-color diagnostic LEDs (X suffix). SIL 3/PL e compliant force-guided contacts ensure reliable safety interlocks in explosive dust atmospheres found in chemical processing, grain handling, and pharmaceutical facilities. The compact design integrates seamlessly into machinery guards while resisting corrosion, impacts, and environmental contaminants.
2. Key Technical Specifications
This switch delivers SIL 3 (PFHD 2.1×10⁻⁹/h) and PL e (ISO 13849-1 Cat. 4) safety ratings with an 8mm magnetic sensing distance. Electrical specifications include 24V DC ±10% operation, dual NC contacts rated for 6A at 250V AC, and M12-4pin P-coded connectivity. The IP67-rated AISI 304 stainless steel housing withstands temporary immersion (1m depth for 30min) and 100g mechanical shocks (IEC 60068-2-27). Environmental resilience includes operation from -25°C to +70°C, UV-resistant PUR cable (ISO 4892-3), and resistance to oils/coolants per ISO 1817. Diagnostic features include 270° visible red/green LEDs with encrypted status patterns. ATEX certification (II 3D Ex tc IIIC T70°C Dc) ensures compliance for Zone 21 combustible dust environments.
3. Hazardous Environment Applications
Designed for safety-critical zones with explosive dust risks:
- Flour Mills: Elevator access hatches monitoring in combustible grain dust atmospheres
- Chemical Powder Processing: Reactor guard interlocks with acid vapor resistance
- Pharmaceutical Blending: Isolator door security in GMP-compliant powder containment
- Coal Handling Facilities: Crusher enclosure safety in Group IIIC dust environments
- Plastics Compounding: Extruder guard monitoring with polymer dust ignition protection
- Feed Production: Mixer safety doors preventing dust cloud ignition
- Metal Additive Manufacturing: Enclosure security for reactive metal powders
- Sugar Refining: Silo access control with combustible dust mitigation
The ATEX Zone 21 certification (IIIC dust group) ensures safe operation where minimum ignition energy (MIE) is <3mJ, while IP67 protection maintains reliability in high-humidity washdown areas.
