59050 Miniature PCB Mountable Reed Switch + 57050 Actuator

Description

The 59050 is a miniature PCB-mountable reed switch, 22.86mm x 4.57mm x

4.32mm (0.900” x .180” x .170”) with a choice of normally open, and normally

open high voltage contacts. It has moulded stand-offs to allow board washing. It

is capable of switching up to 265Vac/300Vdc at 10VA. It functions best with the

matching actuator 57050-000.
