Right, which makes the a height requirement pretty muddy especially if its just some minimum or maximum - how high/low compared to what - floor, catwalk, ceiling, device being activated (or inactivated). The relative distance between actuator and event being controlled might be more important. One probably doesn't want a long conveyor belt to be activate at the output end of the belt but rather at the input to see keep a colleague from being sucked into the machine etc. (although if that is necessary I have a couple of names I could provide :) )
I could maybe by a maximum 0.6 meters from the operator's normal position or something but not just a specified height without other reference.
