Product Detailed
door window contact alarm, position and limit sensing security system switch,reed switch sensor door switch ISO9001 2008

Door window contact alarm  


The principle of Magnetic proximity switches is produce a magnetic field around the sensor through changed the position and polarity of trigger so that make the contacts of the sensor action. Hermetically sealed, life at least 1 million times, easy installation, can adjustment according to different customers' application environment.


Classic design, compact size.

Choice of normal open or normal close

No standby power requirement.

Customer can define activated distance, cable length and connector.

Hermetically sealed, suit to tough environment and long life.
