1. Product Overview
The Schmersal BNS 16-12ZV is a hygienically optimized safety switch engineered for critical access control in washdown environments. Featuring a stainless steel housing (AISI 316L) with IP69K protection, this device utilizes non-contact magnetic sensing with a 16mm operating distance. The "ZV" suffix denotes enhanced chemical resistance against aggressive cleaning agents (pH 0-14). Certified to ISO 13849-1 PL e (Category 4) and IEC 62061 SIL 3, it operates reliably in temperatures from -30°C to +85°C while withstanding 100-bar pressure washdowns and steam sterilization. Integrated dual-color LEDs provide visual status for guard position (green) and diagnostics (yellow), while the electropolished surface (Ra ≤0.4μm) prevents biofilm formation. Its compact design enables installation in space-limited areas of food, pharmaceutical, and chemical processing equipment.
