1. Extended-Reach Corrosion-Resistant Actuator Overview
The Schmersal AZM300B-ST-AS-A is a heavy-duty safety actuator engineered for large-guard applications in aggressive industrial environments. Featuring a 300mm stainless steel tongue (ST profile) with ±10mm lateral tolerance, this device enables precise alignment with Schmersal BNS series safety switches at extended distances. Constructed from acid-passivated AISI 316L stainless steel (A-suffix), it withstands corrosive chemicals (pH 0.5-14), salt spray (ISO 9227 C5-M), and temperatures from -40°C to +150°C. The IP69K-rated design resists 150-bar washdowns while the "AS" designation provides tool-free ±10mm lateral adjustment via slotted mounts. Integrated 128-bit encrypted magnetic coding prevents tampering, and crevice-free electropolished surfaces (Ra ≤0.4μm) meet EHEDG/3-A standards for offshore, chemical processing, and marine applications where chloride-induced corrosion compromises standard actuators.

3. Industrial Applications
This actuator enables safety interlocks in extreme environments:
- Offshore Platforms: Helideck safety gates with saltwater immersion
- Chemical Tankers: Cargo hold access hatches in H₂S atmospheres
- Geothermal Plants: Safety doors in chloride-rich steam environments
- Steel Pickling Lines: HCl mist-resistant roller conveyor covers
