Flange Mount Proximity Reed Sensor Switch, 11mm, 250mA - 

The 59145-4-S-02-A is a 11mm flange-mount Reed Sensor with tinned lead terminals and normally closed contact. This sensor case design allows screw down or adhesive mounting and flying leads can exit either left or right hand side of the housing. Operates through non-ferrous materials such as wood, plastic or aluminium. Hermetically sealed, magnetically operated contacts continue to operate long after optical and other technologies fail due to contamination. Suitable for position and limit sensing, linear actuators, security system switch and door switch applications.
