The OMRON E3F23L is the same sensor as the E3F2-3L — just a shortened order‑code variant. It's a through‑beam photoelectric pair (separate emitter and receiver) with 3 m range, IP67 housing, and a 2 m two‑wire cable. Supply is 30 VDC max, and the operating temperature spans −25 to 55 °C. If your BOM lists E3F2‑3L, this is a direct drop‑in: same mounting ears, same cable exit, same 65 mm body length.
