Best Magnetic Field Sensing

Fielect 5pcs MC-31 Surface Mount Wired N.O. Door Contact Sensor Alarm Magnetic Reed Switch White

Producat Name: MC-31 Magnetic Door Sensor.
[Normally Open] - NO means Normally Open: when the magnet separates, the circuit is conductive( light on ).
When the magnet together, the circuit is not conductive ( light off )..
[Widely Usedl] - This surface mount wired door contact Sensor works with any access control or burglar alarm system available.
[Note] - the Magnetic Door Switch must be installed according to the sensing distance. It can only provide a switch signal to the transmitter. It cannot directly load the power, nor directly connect the lamp!.
[Package Included] - 5Pcs x MC-31 Surface Mount Wired Magnetic Door Sensor.
