MK13 Series

Sensors with mounting holes for screw fastening

Characteristics

MK13 are magnetically operated Reed Sensors with mounting holes and connecting cable.  The technical design corresponds to the series MK4 except for the long mounting holes offering the possibility of individual adjustment.  The sensor should be mounted on a fixed surface with the actuating magnet, e.g. M13, on the moving surface.  The sensor and the magnet must be fixed in a definite distance to each other.  The sensor is mostly operated from he front; approximation resp. removal of the magnet determines the closing or 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

End motion detection for linear device

Machinery industry e.g. end motion detection and door/flap control

Dimensions

Tolerance +/- 0.10mm (0.004 inch)

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 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 (0.2inch)
X Individual crimped terminals 1mm(0.04inch)
Y Individual spade terminals, 2.8 x 0.8mm(0.11 x 0.03inch)
Z “MASCON” sleeve suitable for pcb connector with  2.54mm (0.1inch) pitch
