Banner Engineering S18SN6FF50Q Photoelectric Sensor

The Banner Engineering S18SN6FF50Q is an EZ‑BEAM fixed-field photoelectric sensor from the S18 Series, epoxy‑encapsulated in a barrel‑mount housing for rugged sensing in tight spaces. It delivers a 50 mm infrared sensing range (880 nm) with a DC supply of 10–30 V and a complementary NPN output via a 4‑pin M12 integral quick‑disconnect. Built for harsh environments, the sensor carries IP67 and IP69K ratings and a NEMA 4X designation, making it resistant to dust, moisture, and high‑pressure washdowns. The S18SN6FF50Q employs Banner’s EZ‑BEAM optics to provide reliable presence detection within a fixed field without field adjustments, and it supports Dark‑ON/Light‑ON operation to accommodate targets with varying contrast. Applications include part presence detection on conveyors, packaging lines, and general automation where a compact, epoxy‑encapsulated receiver is required.
