1.1 Outline
The H8PS Cam Positioner is an electronic cam switch that allows you to make complicated ON/OFF angle
settings in a simple operation.
Conventionally, a combination of a mechanical cam and a limit switch (or photoelectric sensor) was used
to detect angles of rotation.
This conventional method, however, required a very cumbersome process when adjusting an angle.
The H8PS Cam Positioner detects angles of rotation using an absolute encoder (a sensor that detects the
absolute angle of rotation) to turn the output signal on and off at the preset ON/OFF angles (referred to as
the "cam program").
The H8PS Cam Positioner can replace existing mechanical cam switches.
The H8PS Cam Positioner offers a number of advantages over a cam positioner unit of a PLC (program-
mable logic controller), including its easy-to-read display and the simple procedure for changing settings.
Also you do not have to consider the adverse affect of scan time.
