• Encoder E1+E2: A 2-channel rotary encoder with HTL square-wave signal must be used. Channel A is
displaced 90° relative to channel B. It must be assured that a shielded cable is used in order to avoid pos-
sible interference or crosstalk between the conductors.
• Encoder reset: The encoder is reset to “0”.
• Laser off: The laser can be switched on or off by activating the input load or the input voltage.
Output:
• PNP output: The load or the analysis module is connected between the minus pole (reference) and the
output. When switched, the output is connected to the plus pole via an electronic switch. A PNP output
can also be equipped with a pull-down resistor.
• NPN output: The load or the analysis module is connected between the plus pole (reference) and the out-
put. When the sensor is switched, the output is connected to the minus pole via an electronic switch. An
NPN output can also be equipped with a pull-up resistor.
• Push-pull: alternate PNP and NPN switching
Output function:
• The output can be configured as NO (normally open) or NC (normally closed).
Teach-in mode:
• Teach-in: a function by means of which the sensor is caused to automatically calculate and save future set-
tings based upon momentarily acquired values by pressing a button or applying a control signal.
• FT teach-in mode (window teach-in): There are two switching points in the case of window teach-in. The dis-
tance between the two switching points is called the window. The size of the window is designated window
width. The sensor is switched when an object is within the window.

• VT teach-in mode (foreground teach-in): Teach-in is performed while the sensor is aligned to the object.
