Magnetically operated Reed Sensors with screw thread enclosure
Characteristics
MK11 sensors are magnetically operated Reed Sensors with screw thread enclosure supplied with interconnect cable. The sensor should be mounted on a fixed surface with the actuating magnet on the moving surface. The sensor and magnet must be fixed in a definite distance to each other. The sensor is mostly operated from the 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
Piston end travel and position detection
End motion detection for linear drives
Machinery industry
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).
