MK14 Series MEDER electronic Cylindrical Reed Sensors DESCRIPTION MK14 sensors are magnetically operated Reed proximity switches in a 4.0 mm diameter miniature module, fitted with interconnect cable. 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 • End motion detection for linear drive Indication and end travel limit switch • Limit and motion detection for machine industry FEATURES • 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] www.meder.com 238 MEDER electronic MK14 Series Cylindrical Reed Sensors ORDER INFORMATION Part Number Example Series Contact Form Switch Model Magnetic Sensitivity Cable length (mm) Termination MK14 - XX XX X- XXX X 66 B, C, D, E 200 * W 1 Form A 84 Options 1 Form B 1 Form C C, D, E MK14 - 1A66 C - 200 W 1A is the contact form 66 is the switch model C is the magnetic sensitivity 200 is the cable length (mm) W is the termination 90 * Other cable lengths available MAGNETIC SENSITIVITY Sensitivity Class Pull-in At Range B 10 - 15 C 15 - 20 D 20 - 25 E 25 - 30 TERMINATION For wire and termination details please consult factory.
