59020
Miniature Cylindrical Reed Sensor + 57020 Actuator
Description
The 59020 Reed Sensor is a miniature cylindrical reed sensor 15.24mm x 5.10mm
(0.600” x 0.201”) with a normally open contact. It is capable of switching up to
120 Vac/170 Vdc at 10 VA. The 59020 Reed Sensor is available with a range of
sensitivity and cable length options. It is well suited for use in a wide range of
industrial, appliances, or IoT proximity sensing applications. It functions best
with the 57020-000 actuator.
Note: The 57020 Actuator is sold separately.
