MEDER electronic MK37 Recessed Reed Sensors
MEDER electronic MK37 Recessed Reed Sensors are noncontact magnetic sensing devices designed for recessed installation in doors, windows, enclosures, and equipment. The sensors are designed to press into a Ø9.5mm mounting hole and are available with a normally open (Form A) or normally closed (Form B) contact configuration. The MK37 series supports industrial equipment, building security, monitoring systems, appliance door detection, and access control applications. Installation flexibility is enhanced through optional adapter accessories for steel mounting environments, along with multiple cable and housing options. The sensors offer IP67 protection and are available with UL cable versions supplied as sensor and magnet pairs or VdS cable versions sold separately. MEDER electronic MK37 Recessed Reed Sensors provide reliable magnetic activation using the M37-N42 actuator and support a wide operating temperature range.
