Parameters Electrical Contact Configuration: 1 Normally Open (1 NO) + 1 Normally Closed (1 NC) auxiliary contacts — allows both stop signal and feedback/status signal. Rated Operational Voltage: Suitable for a wide range of control voltages in low‑voltage AC/DC systems. Rated Current: Sized for typical control circuit duties up to moderate amperages (e.g., around 1–10 A depending on voltage). Insulation & Withstand: Meets general control‑circuit insulation and transient withstand requirements. Mechanical & Environmental Operation: Emergency stop with maintained latching — stays engaged until key release. Mechanical Durability: Designed for frequent use with a long operational life. Operating Temperature: Suitable for standard industrial panel ambient temperatures. Protection Ratings: Front Panel Protection: Offers resistance to dust and water ingress when correctly installed in compatible enclosures. Terminal Protection: Basic touch protection at terminals when installed inside an enclosure. Physical & Installation Panel Cut‑out: Standard 22 mm diameter pilot‑device hole. Actuator Diameter: 40 mm mushroom head for emergency actuation. Body / Bezel: Compact plastic housing designed for flush panel mounting. Terminal Type: Screw terminals for reliable conductor connection. Typical Applications Emergency stop inputs on industrial machinery and automation systems. Safety panels and operator interfaces requiring manual emergency control. Control logic circuits where both stop command and status feedback are needed. Human‑machine interface (HMI) stations for industrial equipment.
