The sensors of the lpc sensor range
have an extremely narrow beam spread with an operating range of 250 mm and a maximum range of 350 mm. The blind zone amounts to a mere 30 mm.
3 output versions are available:
|2 switching outputs, optionally in pnp or npn circuitry|
|1 analogue output 4–20 mA and 0–10 V|
|1 analogue output with an additional pnp switching output
Via pin 5 at the circular connector,
the lpc sensors are set (Teach-in): If pin 5 is connected to +UB, the D1 switched output is set; if pin 5 is connected to –UB, the D2 switched output is set. With the sensor version with analogue and switched output, the analogue output is set with pin 5 connected to +UB and the switched output is set with pin 5 connected to –UB.
Two yellow LEDs,
which are laterally arranged at the M18 threaded sleeve, indicate the sensor output states and support the Teach-in procedures.
The lpc sensors with switched output
have three operating modes:
- Single switching point
- Two-way reflective barrier
- Window mode
A single switching point is set by:
- positioning the object to be detected within the desired distance (1) to the sensor,
- connecting pin 5 to +UB (for switched output D1) or –UB (for switched output D2) for avout 3 seconds until both LEDs flash,
- once more connecting pin 5 to +UB (for D1) or –UB (for D2) for about 1 second until the corresponding LED go out.
