MK5-
Series
Magnetically operated Reed Sensor with long hole for
screw fastening
Characteristics
MK5 sensors are magnetically operated
Reed proximity switches designed for screw mounting. The sensor should
be mounted on a fixed surface with the actuating magnet, e.g. M5, 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. A choice of switches, termination options and cable lengths
is offered.
Applications
- Position- and limit switch
e.g. pneumatic or hydraulic actuator position indication and
end travel
limit switch
- Door and window contacts
for the security system applications
- Level sensor
use with magnetic flats for water level detection e.g. coffee-makers,
washing-machines, dish-washers

Termination
The standard termination is a
two-wire flat cable with a cross section of 2 x 0.14mm². The standard
length of the cable is 500mm, other lengths can be supplied on request.
The required length has to be noted on the part number.
The cable end can be supplied with the following connection styles (please
note after the length in the part number).
