Product Overview
The Littelfuse 59135 is a high-temperature flange-mount reed sensor designed for reliable position and limit sensing in demanding environments. Featuring a robust thermoset overmold and Teflon-insulated wires, it operates effectively up to 150C. This magnetically operated proximity sensor offers a choice of contact types (Normally Open, Normally Open High Voltage, Normally Closed, Change Over) and is rated for switching up to 265Vac/300Vdc at 10VA. Its hermetically sealed contacts ensure longevity, even in contaminated conditions, and it requires no standby power. The sensor is optimized for use with the matching 57135 actuator and is suitable for applications including security systems and linear actuators.
