MK7-1A81A-500T

MK7 Series Cylindrical Reed Sensors with M8 Thread MEDER electronic DESCRIPTION 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 MK7 sensors are magnetically operated Reed proximity switches in a cylindrical form with an 8 mm x 0.75 thread and connecting cable or coupler. The sensor can be screwed directly onto a fixed surface with the actuating magnet on the moving surface. The widespread termination “T” or “U” makes the MK7 series compatible with several inductive and magnetic proximity sensors. 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 DIMENSIONS All dimensions in mm [inches] 182 Germany # ++49-(0)7733-94870, USA # 800-870-5385 www.meder.com MEDER electronic MK7 Series Cylindrical Reed Sensors with M8 Thread ORDER INFORMATION Part Number Example MK7 - 1A66 C - 500 W SERIES MK 7 MK7/1 CONTACT FORM XX SWITCH MODEL XX 66 1 Form A Optionen 51** 1 Form B 1 Form C C, D, E 90 81 MAGNETIC SENSITIVITY XB, C, D, E A 500* W, X, Y, T, U CABLE LENGTH (mm) XXX TERMINATION X 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 * Other cable length available. ** Not available in combination with MK7/1 serie.
