59135 Series
High Temperature Flange Mount Sensor
Description
The 59135 is a high temperature flange mounting reed sensor
28.57mm x 19.05mm x 6.35mm (1.125” x 0.750” x 0.250”) with a
choice of normally open, normally closed or change-over contacts.
It is rated for operation up to 150°C and capable of switching up to
265Vac/300Vdc at 10VA.
The 59135 series is well suited for use in a wide range of
industrial, appliances, or IoT proximity sensing applications.
Note: The 59135 series functions best with the matching actuator 57135-000.
