KJT intrinsically safe NAMUR proximity switches are mainly used in equipment and environments that require explosion protection, such as coal mines, petrochemicals, etc. The NAMUR signal is the most widely used intrinsically safe digital input and frequency input standard signal in the world. The earliest is the German standard (DIN19234). Later it became a European standard (EN 50227, DIN EN 60947-5-6). The NAMUR signal is a passive 2-wire system, nominal 8VDC power supply, 1mA and 3mA switching signals. NAMUR type sensors are intrinsically safe explosion-proof instruments and are usually used in conjunction with isolated safety barriers.
