59141 Miniature Flange Mount Sensor
Flange Mounting Sensor
Description
The 59141 is a miniature flange mounting reed sensor occupying
only 3.22cm² (0.500”²) board space with a choice of normally
open, normally open high voltage, normally closed or changeover
contacts. The wires exit from the left-hand side, see Drawing 2. It
is also available with right-hand exit - see 59140 Series. The 59141
series is capable of switching up to 265Vac/300Vdc at 10VA. It is
well suited for use in a wide range of industrial, appliances, or IoT
proximity sensing applications.
The 59141 functions best with the matching actuator 57141-000.
