Sick PL21MS07P11 Photoelectric Sensor Reflector

Sick PL21MS07P11 Sensor Reflector is a standard reflector accessory for the SICK PL21 retroreflective photoelectric sensor family. It serves as the optical reflector in a retroreflective sensing setup, reflecting the emitter’s light back to the sensor to enable reliable detection of objects within the PL21’s sensing path. The part is identified as PL21MS07P11 with an internal code of 1053122 and is shown in distributor listings as “SICK PL21MS07P11 Sensor Reflector” (also referenced as #325943). The reflector is designed to be installed horizontally to maintain proper optical alignment with the PL21 sensor. It is intended for use with compatible SICK PL21 retroreflective sensors in industrial automation applications where a compact, robust sensing arrangement is required, such as inline conveyors, access points, or machine guarding setups where a dedicated reflector is used rather than a through-beam pair. When installed and aligned correctly, the PL21MS07P11 reflector provides a simple, reliable reflector path that helps minimize misreads due to ambient light or surface finish, making it a practical accessory for PL21-based retroreflective sensing configurations.
