Product Overview
The Littelfuse 59145 is a flange-mounting reed sensor designed for position and limit sensing, security systems, linear actuators, and door switches. This two-part magnetically operated proximity sensor offers a choice of contact types (Normally Open, Normally Open High Voltage, Normally Closed, or Changeover) and customer-defined sensitivity options. Its hermetically sealed, magnetically operated contacts ensure reliable operation in contaminated environments, with no standby power requirement. The sensor can switch up to 265Vac/300Vdc at 10VA and functions optimally with the matching 57145 Actuator. The case design allows for screw or adhesive mounting, with wires exiting from the top right or left (59150 Series).
