SICK WL150-P430 6011038 W150 Miniature Retro-reflective Photoelectric Sensor PNP 2.4m

SICK WL150‑P430 (6011038) is a miniature retro‑reflective photoelectric sensor of the W150 series. It is based on a double‑lens optical system and a visible red LED light source. The integrated polarising filter suppresses false switching signals on shiny or reflective surfaces. The sensor is suitable for presence detection, position monitoring and counting tasks in industrial automation lines, including the detection of transparent objects.

Applications:

• Fast object presence and position monitoring on conveyor systems

• Transparent object detection in packaging and bottling machines (e.g. glass, plastic bottles, films)

• High‑speed counting and quality verification on production lines

• Positioning of components in pick‑and‑place installations

• Presence control of small parts in automated assembly cells

• Items supplied: Mounting bracket BEF‑W150‑A, reflector PL20A (alternative to PL80A)

System Integration:

• This sensor belongs to the SICK W150 series of miniature photoelectric sensors.

• A separate reflector (e.g. PL20A or PL80A) is required for operation; PL20A is included in the scope of supply.

• Mount the sensor via the included BEF‑W150‑A bracket or optional mounting brackets.

• Wiring details: M8 4‑pin male connector (pin 1: V+, pin 3: V‑, pin 4: output); the light/dark switching function is selected via the L/D control wire.

• Adjust the sensing threshold by turning the 270° potentiometer.
