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) 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 meder electronic mk6 series reed sensors for pcb mounting part number example mk6 - 4 - c 4 is the packaging size c is the magnetic sensitivity order information magnetic sensitivity description features ? form a, b, c and e (latching) available ? high power switches available ? various case sizes available ? five operate sensitivities available part number example mk6 - 10 - e e selects the latching option ww w .willow.co.uk tel. +44 (0) 1342 835234 fax. +44 (0) 1342 834306 sensitivity class pull in at range a 5 - 10 b 10 - 15 c, h 15 - 20 d, i 20 - 25 e, k 25 - 30 series packaging size magnetic sensitivity mk6 - x - x options 4b , c , d , e 5 b, c 6 a, b, c, d, e 7 a, b, c, d, e 8 (form a) a, b, c, d, e 8 (form c) h, i, k series contact form mk6 - 10 - x * options b e * see footnote on following page.
mk6 series meder electronic reed sensors for pcb mounting all dimensions in mm [inches] dimensions * 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. ww w .willow.co.uk tel. +44 (0) 1342 835234 fax. +44 (0) 1342 834306
