Panasonic SunX CX-23-PN-J Photoelectric Switch

The Panasonic SunX CX-23-PN-J is a compact photoelectric sensor from the CX-20 family designed for non-contact object detection in tight spaces. Listed as CX-23-PN-J (Compact photoelectric sensor, CX-20 series), this model is a discontinued item with catalog entries dating to 2005. It offers switchable Light-ON or Dark-ON operation to suit different background materials and ambient light conditions. Older CX data lists a sensing range up to 5 meters (approximately 16.4 feet), enabling detection of targets at a distance while preserving a small form factor. As part of the SunX photoelectric line, the CX-23-PN-J serves in environments where space is limited and precise presence/absence sensing is required, such as compact automation cells or packaging and conveyor setups that benefit from a non-contact sensing solution. Designed for tight-space automation tasks, its non-contact detection helps reduce wear on moving parts and supports quick, maintenance-light integration in legacy SunX installations.
