Product Description

KJT intrinsicically safety Namur proximity switch is mainly used in equipment and environment requiring explosion-proof, such as coal mine, petrochemical, etc. Namur signal is a standard signal suitable for a wide range of intrinsically safe digital input and frequency input in the world. Its suitability was as early as the German standard (din19234). Later, it became a European standard (EN 50227, DIN 60947-5-6). Namur signal is passive 2-wire system, nominal 8vdc power supply, 1mA} and 3mA switching signals. Namur sensors are intrinsically safe explosion-proof instruments, which are usually used in conjunction with isolated safety barriers.
