The TopWorx TXS-L21GNMM is an explosion-proof electromechanical limit switch engineered for position feedback in hazardous industrial environments. Featuring a rugged 316 stainless-steel housing with ATEX/IECEx/IEC 60079 certifications, it operates safely in Zone 1/21 gas/dust atmospheres.
The switch integrates dual SPDT contacts (form Z) rated for 5A @ 250VAC and utilizes a field-adjustable roller lever actuator (suffix "MM") for precise valve stem engagement. Its IP68-rated enclosure withstands high-pressure washdowns, extreme temperatures (-50°C to +85°C), and corrosive chemicals.
Designed for direct mounting on quarter-turn valves/actuators, it provides reliable open/closed status to control systems via NAMUR (EN 60947-5-6) or standard electrical outputs.
