A miniature flange mount reed sensor occupying only 3.22cm2 (0.500in2) board space with a choice of normally open, normally open high-voltage, normally closed or changeover contacts. Its case design enables screw or adhesive mounting. Wires exit from top left-hand side. Also available with right-hand exit (59140 series). Capable of switching up to 265Vac/300Vdc at 10VA. Available with a range of sensitivity and cable length options. Ideally suited for position and limit sensing, security, window and door alarm systems and linear actuator applications. Functions best with the 57140 or 57141 actuator.

Note: The 57140 and 57141 actuators are sold separately.
