Meder Electronic MK13 Series Reed Sensors with Screw Fastening Mounting Holes DESCRIPTION MK13 sensors are magnetically operated Reed proximity switches in a case with an 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 • Machine industry End motion detection and door/flap control 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] www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK13 Series Meder Electronic Reed Sensors with Screw Fastening Mounting Holes ORDER INFORMATION Part Number Example SERIES CONTACT FORM SWITCH MODEL MAGNETIC SENSITIVITY CABLE LENGTH (mm) TERMINATION MK13 - XX XX X - XXX X 71 B, C, D, E 81 A 500 * W, X, Y 1 Form A OPTIONS 84 1 Form B 1 Form C MK13 - 1A71 C - 500 1A is the contact form 71 is the switch model C is the magnetic sensitivity 500 is the cable length (mm) W is the termination C, D, E 90 * Other cable lengths available.
