Cylindrical Reed Sensors
MK20 sensors are magnetically operated Reed proximity switches in a cylindrical module, fitted with interconnect cable. The sensor should be mounted on a fixed surface with the actuating magnet, e.g. M3, on the moving surface. Introduction and removal of the magnetic field determines the closing and opening of the Reed Switch. The magnetic pull-in / drop-out sensitivity is divided into three AT ranges. A choice of switches, termination options and cable lengths is offered.
Position and limit switch, Pneumatic or hydraulic actuator position indication and end travel limit switch
Security system applications, door and window contacts
Level sensor, use with magnetic floats for water level detection i.e. coffee- makers, washing-machines, dish-washers
Tolerance +/- 0.10mm (0.004 inch) (Flat side indicates maximum sensitivity)
The standard termination is a two-wire flat cable with a cross section of 2 x 0.14mm². The standard cable length is 500mm, other lengths can be supplied on request. The required length has to be stated on 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) diameter|
|Y||Individual spade terminals, 2.8 x 0.8mm(0.11 x 0.03inch)|
|Breakdown voltage (contact/contact)||min.||(VDC)||200|
|Operating time incl. bounce||(ms)||0.4|
Other switches by request.
|Pull-in AT range||10-15||15-20||20-25|
This data relates to unmodified Reed Switches before mounting. Please refer to the respective single data sheets for sensitivity data and measurement methods for finished assemblies.
