1. High-Performance Safety Actuator Overview
The Schmersal AZM 201B-ST-T-AS-A-P is an industrial-grade actuator engineered for critical safety interlocking in harsh environments. Featuring a 201mm extended tongue length with ST-profile geometry, it enables precise alignment with Schmersal BNS/BDF series safety switches at distances up to 200mm. Constructed from electropolished AISI 316Ti stainless steel (ST suffix), this actuator withstands extreme temperatures (-60°C to +150°C), high-pressure washdowns (IP69K), and corrosive chemicals (pH 0.5-14). The "T" denotes enhanced temperature resistance, "AS" provides ±5mm lateral adjustment, "A" indicates acid-passivated surface treatment, and "P" specifies PUR cable integration. Certified to ISO 13849-1 PL e (Category 4) compatibility, its 128-bit encrypted magnetic coding prevents tampering while crevice-free design meets EHEDG/3-A standards for pharmaceutical, chemical, and offshore applications.
2. Critical Technical Specifications
- Mechanical:

3. Extreme Environment Applications
This actuator serves safety-critical roles in:
- Oil & Gas: Wellhead control panel guards in sour gas (H₂S) environments
- Chemical Processing: Reactor access hatches with sulfuric acid exposure
- Geothermal Plants: Safety gates in H₂S/chloride-rich atmospheres
- Marine Engineering: Offshore platform hydraulic unit guarding
- Food Processing: High-temperature retort systems (135°C sterilization)
- Steel Pickling Lines: HCl mist-resistant roller conveyor covers
- Pharmaceutical Autoclaves: Sterile transfer hatches with SIP cycles
- Waste Incineration: Ash handling equipment access control
Its titanium-stabilized SS316Ti construction prevents sensitization during prolonged 150°C exposure, while PUR cable resists hydrolysis in 95% RH environments.
