MK2/4 Magnetically operated Reed Sensor with round cable for screw fastening
MK2/4 sensors are magnetically operated Reed proximity switches designed for screw montage. The sensor should be mounted on a fixed surface with the actuating magnet on the moving surface. The Reed Sensor and the magnet must be fixed in a definite distance to each other. Approximation resp. removal of the magnet determines the closing and opening of the Reed Switch. The magnetic pull-in / drop-out sensitivity is divided into five AT ranges.

The standard termination is a two-wire UL-approved round cable with a cross section of 2 x 0.35mm². The standard cable length is 500mm, other lengths can be supplied on request. The required length has to be stated in the part number. The cable end can be supplied with the following connection styles (please note after the length in the part number).
|W||Cable end cut, dismantled on 30 mm, cores stripped and tinned on 5 mm|
|X||Individual crimped terminals 1mm(0.04inch) diameter|
|Y||Individual spade terminals, 2.8 x 0.8mm(0.11 x 0.03inch)|
