电感接近传感器DC8 .... SA系列

圆柱形 防爆 带LED灯

• NAMUR SERIES WITH LED diameter 8 mm • ATEX certified II 1GD for zone 0;20 • Connector output M12 x 1 General features: With this new series of sensors it’s possible to drive specific inputs for NAMUR sensors or inputs for 2 wires amplified switches with low current (up to 10 mA). The load can be applied on both terminals (function PNP or NPN). The output is internally triggered and monitored by LED.
