Mounting Footprint And Adjustability Dimensions - Martek Chicken Switch Instruction Manual


Is the mounting surface clean, flat, and clear of any obstructions? A mounting surface that has
depressions, raised areas, holes, labels, or is just dirty may not be able to allow the magnet to
adequately attach.
For detailed information on the amount of space required to mount the actuator, see Section 4.1.

Mounting Footprint and Adjustability Dimensions

The PB-16 is designed to have some dimensional adjustability so that it can be adapted for use in various
pushbutton layouts. The following dimensions are adjustable:

Reach from the edge of the magnet

Plunger height above the pushbutton

Stroke is 2" maximum. Actuator will press with up to 22 lbs of force. The plunger will stop
moving once 22 lbs is reached (stall) or it reaches its full 2" stroke. We have found that 22 lbs is
adequate force requirement for most pushbuttons but also it not so great that it will damage your
button or push the actuator off the door. Additional force pressures are available and may work
satisfactorily in your installation. If you feel that you have a unique application, please contact
MarTek Limited for more information.
The following picture shows the foot print of the mounting magnet that attaches the PB-16 to your
equipment. This foot print is the area that touches your equipment which is the area on your equipment
that must be clear of anything that could obstruct mounting the PB-16.
With the plunger in the retracted position, the actuator can be infinitely adjusted so that the
plunger is anywhere from 0.30" to as much as 1.40" above the magnet mounting surface (which
is normally the surface of your equipment). The plunger can extend up to 2".
Therefore, in the lowest position (0.30"), the plunger can push into a recessed hole as far as
1.70". In the highest setting (1.40"), the plunger can push into a recessed hole as far as 0.60"
