Reed Sensors Flange Mounting Sensor > 59140 59140 Miniature Flange Mount Sensor + 57140 Actuator Description The 59140 is a miniature flange mounting reed sensor occupying only 3.22cm² Actuator (0.500”²) board space with a choice of normally open, normally open high voltage, normally closed or changeover contacts. It’s case design enables screw or adhesive mounting and the wires exit from top right hand side. It is also available with left hand exit - see 59141 Series. It is capable of switching up to 265Vac/300Vdc at 10VA. The 59140 functions best with the matching actuator 57140-000. Sensors Note: The 57140 Actuator is sold separately.
