Meder Electronic MK6 Series Reed Sensors for PCB Mounting DESCRIPTION MK6 sensors are magnetically operated Reed proximity switches for direct PCB 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. (2.54 mm PCB pin spacing, available with different distances) FEATURES • Form A, B, C and E (Latching) available • High power switches available • Various case sizes available • Five operate sensitivities available ORDER INFORMATION APPLICATIONS • Telecommunications Telephone hook switch, keyboard applications • Domestic appliances Door switch for washing machines, dishwashers, microwave ovens, baking ovens, refrigerators • Limit switch for low-power signals Garage door controls, lever hoists, conveyors • Lifts / elevators Position indicators MAGNETIC SENSITIVITY SERIES PACKAGING SIZE MAGNETIC SENSITIVITY SENSITIVITY CLASS PULL IN AT RANGE MK6 - X - X A 5 - 10 4 B, C, D, E B 10 - 15 5 B, C C, H 15 - 20 6 A, B, C, D, E D, I 20 - 25 7 A, B, C, D, E E, K 25 - 30 8 (Form A) A, B, C, D, E 8 (Form C) H, I, K OPTIONS SERIES CONTACT FORM MK6 - 10 - X* Part Number Example MK6 - 4 - C 4 is the packaging size C is the magnetic sensitivity B Part Number Example E MK6 - 10 - E OPTIONS E selects the latching option * See footnote on following page. www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 MK6 Series Meder Electronic Reed Sensors for PCB Mounting DIMENSIONS All dimensions in mm [inches] * MK6-10-E is a magnetic latching sensor which is opened or closed by a passing magnet and remains in that state until a magnet of opposite polarity or direction passes by again. The E refers to a latching sensor and does not represent the magnetic sensitivity. MK6-10-B is a normally closed sensor. The B refers to a latching sensor and does not represent the magnetic sensitivity. www.willow.co.uk Tel. +44 (0) 1342 835234 Fax. +44 (0) 1342 834306 Meder Electronic MK6 Series Reed Sensors for PCB Mounting CONTACT DATA All data at 20 0 C Switch Model --> Contact Form --> Packaging styles --> Contact Ratings Conditions Contact 71 Form A, B, E 6, 7, 8, 10 Min.
