MK05 Series MEDER electronic Reed Sensors with Screw Fastening Slot DESCRIPTION MK5 sensors are magnetically operated Reed proximity switches designed for screw mounting. The sensor should be mounted on a fixed surface with the actuating magnet on the moving surface. Introduction or removal of the magnetic field determines the closing and opening of the Reed Switch. APPLICATIONS • Position and limit switch Pneumatic or hydraulic actuator position indication and end travel limit switch • Door and window contacts Security system applications • Level sensor Use with magnetic floats for water level detection in coffee makers, washing machines or dishwashers FEATURES • • • • • • Form A, B, and C available High power switches available Other cables, connectors and colors available Various case sizes available Five operate sensitivities available A choice of cable terminations and lengths are available • High voltage versions upon request DIMENSIONS All dimensions in mm [inch] www.meder.com 222 MEDER electronic MK05 Series Reed Sensors with Screw Fastening Slot ORDER INFORMATION Part Number Example MK5 - 1A66 C - 500 W 1A is the contact form 66 is the switch model C is the magnetic sensitivity 500 is the cable length (mm) W is the termination Series Contact form Switchmodel Magnetic Sensitivity Cable Length (mm) Termination MK4 - XX XX X- XXX X 66 B, C, D, E 85 C, D, E 500* W 1 Form A Options 1 Form B 1 Form C 90 * Other cable length available.
