The Keyence PZ2-42P is a diffuse-reflective photoelectric sensor with a 100 mm sensing range and a 12–24 V DC supply, featuring a PNP output for direct connection to control logic. In diffuse-reflective mode, it detects targets by measuring reflected light from surfaces within its detection distance, with performance influenced by surface reflectivity and color. The PNP output sources current to the connected load when a target is detected, enabling straightforward interfacing with PLC inputs or relays without additional interface circuitry.
