Product information
Small, robust, effective, and reliable - these
are the properties of the ML7 sensor series.
Due to their small size, number of versions,
and two different lens positions, they are par-
ticularly suited for installation in tight spaces.
The robust design and high quality of Pep-
perl+Fuchs mean they can also be used
under harsh environmental conditions. The
efficient technology, switching frequencies up
to 1000 Hz, high resistance to ambient light,
and 4-in-1 output make the series suitable for
non-contact object detection.

Connect the sensor to operating voltage, the LED green lights up constantly. The sensor operates at max. sensitivity (delivery status) or with
the last teached values.
Mount suitable reflector opposite light beam switch.
•Adjust the unit to the reflector.
• Press the Teach-In button - as an acknowledgement the green LED will quickly turn off one time.
• Press the Teach-In button until both LEDs green and yellow are blinking in parallel (2Hz). Release the Teach-In button now.
• While the green and yellow LEDs are blinking alternating (2 Hz) the unit is in the internal set up procedure.
•Teach-In successful: Both LEDs green and yellow are on. The unit is ready to use and in switching mode now.
•Teach-In not successful: Both LEDs are flashing alternating (4 Hz) for approx. 5 seconds. Afterwards the sensor returns to max. sensitivity
setting. Please retry the Teach-In procedure beginning by step 1.
