Key Features Actuator Type: Red mushroom head pushbutton for emergency stop or prominent control input. Action: Maintained (latching) — stays in the actuated position until manually reset. Operator Only: Requires separate modular contact blocks for electrical switching. Design: Compact, rugged construction suitable for industrial environments. Panel Mount: Standard 22 mm diameter mounting hole. Bezel/Housing: Plastic housing with robust mechanical design. Electrical Parameters Contact Blocks: Sold separately — can be fitted with 1 NO, 1 NC, or combinations as needed. Rated Insulation Voltage: Suitable for low‑voltage control circuits up to typical industrial levels. Switching Capability: Depends on the contact blocks chosen (pilot duty control circuits). Control System Compatibility: Ideal for interfacing with PLC inputs, relay coils, and contactor control circuits. Mechanical & Environmental Actuation Type: Maintained — the pushbutton stays engaged until reset. Operating Temperature Range: Designed for typical industrial ambient conditions. Storage Temperature Range: Wide storage temperature range. Front Protection: High ingress protection at the front when installed properly (resistant to dust and moisture). Terminal Protection: Basic touch protection at terminals when mounted in a panel enclosure. Physical & Installation Mounting Hole: 22 mm standard panel cut‑out. Overall Diameter: Approximately matching standard 22 mm pilot device form factor. Depth: Compact behind‑panel depth. Terminals: Screw‑type terminals (via installed contact blocks). Weight: Lightweight modular operator. Typical Applications Emergency stop operator in control panels. Manual stop or latching control in industrial automation. PLC and control logic input point when combined with appropriate contact blocks. Machinery operator stations requiring a clearly visible control input. Human‑machine interface (HMI) panels needing a maintained control input.
