Meder MK6-4-A Reed sensors for pcb mounting Datasheet

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

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.
