The KEYENCE EZ-18T NUPI Through-Beam Photoelectric Sensor uses a through-beam configuration with a separate emitter and receiver to perform non-contact object detection. In this setup, an object crossing the beam interrupts the emitted light, generating a detection event without physical contact. The model designation EZ-18T NUPI identifies this device within KEYENCE’s EZ-18T family of through-beam photoelectric sensors.
