In flammable and explosive industrial environments, safety is not only a principle but also a bottom line.
KJT intrinsically safe explosion-proof NAMUR proximity switches are designed specifically for hazardous environments. With their inherently safe explosion-proof design, they control risks at the signal source, providing reliable detection and protection solutions for high-risk scenarios such as coal mines and chemical plants.
✅ Intrinsically Safe, Eliminating Spark Risk
KJT intrinsically safe explosion-proof NAMUR proximity switches strictly adhere to the international NAMUR standard (EN 60947-5-6), fundamentally eliminating the risk of electrical sparks through low-voltage, low-current operation.
In conjunction with isolated safety barriers, they form a complete explosion-proof system with dual-channel input and output, truly achieving signal safety and system reliability.


✅ Robust Casing, Stable Protection
Utilizing a unibody metal casing and full potting process, it boasts excellent waterproof, dustproof, and corrosion-resistant properties.
It operates stably in humid, hot, dusty, oily, or chemically corrosive environments, ensuring consistently accurate measurement and control data.

✅ Compact Design, Hassle-Free Installation
Its compact size allows for flexible installation in confined spaces or complex setups.
Even in scenarios with high-density cabling or multi-device integration, it ensures measurement accuracy and system stability.

✅ Application Scenarios, Enabling Safety
Coal Mining Industry: Precisely detects the movement position of hydraulic supports and provides real-time feedback on equipment operation status.
Intrinsically safe explosion-proof design avoids the risk of electrical sparks, ensuring synchronized and safe advancement of the working face.
Chemical Industry: Stably monitors the opening and closing status of pipeline valves, ensuring reliable and controlled production processes with low-power signal transmission.
Oil and Gas Industry: Adaptable to explosion-proof environments, monitoring equipment location and operating status, providing high-safety-level process signal detection.

✅ A Reliable Choice for Explosion-Proof Safety
KJT Intrinsically Safe Explosion-Proof NAMUR Proximity Switches, with safety, accuracy, and stability as their core principles,protect the monitoring and control safety of every flammable and explosive environment.
