1. Hygienic Actuator Overview
The Schmersal AZ 16 ST1-AS R is a stainless steel safety actuator engineered for harsh industrial environments requiring corrosion resistance and hygienic design. Featuring a 16mm actuator tongue (ST1 profile) with IP69K-rated AISI 316L construction, this device enables precise alignment with magnetic safety switches like the BNS/BDF series. The "AS" suffix denotes adjustable mounting for ±3mm lateral tolerance, while "R" signifies red visual signaling for high visibility. Designed to withstand -30°C to +85°C temperatures, it resists high-pressure washdowns (100 bar), chemicals (pH 1-14), and UV exposure. With EHEDG-compliant crevice-free surfaces (Ra ≤0.8μm) and electropolished finish, it meets FDA/3-A standards for food, pharmaceutical, and chemical processing applications where bacterial growth prevention is critical.
