MK02 Reed Sensors

MK02 Reed Sensors

The MK02 reed proximity switches operate when in the presence of magnetically conductive material. Instead of an actuating magnet, only a simple piece of iron is required to operate the sensor from the front or from above. These sensors are available as Form A and Form B switches. The standard cable is a UL-listed round twin core 2 x 0.35mm2 (AWG22). 
They are an excellent alternative to inductive proximity sensors and require no power to operate. The MK02 Series provide user the ability to set tolerances, independent of a magnet. They are suitable for a wide range of applications including end travel sensing limit switches, position control, and security uses such as door and window control, opening recognition contact and metal fire protection doors.
