The Schneider Electric XU2-B18KP340T is a photoelectric emitter — the light-source half of a through-beam sensor pair. It does not detect objects on its own; it requires a separate receiver (such as the XU2M18MB230KR) aligned across the sensing gap. The emitter continuously projects a beam; the receiver's output switches when the beam is interrupted.
The XU2-B18KP340T is listed as current production, so it remains a qualified part for BOMs in serial production without requalification risk.
