SICK Sensor Intelligence WT18-P115S14 Photoelectric Switch

The SICK WT18-P115S14 Photoelectric Switch is a compact, non‑contact sensor that detects the presence or absence of objects by using a light beam to generate a switching signal in industrial environments. It operates on a supply voltage of 10 to 30 V DC and is delivered with a 4‑wire cable for power and signal connections. This listing describes a WT18-P115S14 unit that is refurbished. As part of the WT18 family, it embodies SICK’s approach to reliable photoelectric switching for automation tasks that require discreet, maintenance‑friendly sensing in tight spaces or on small-form components. For exact electrical wiring, sensing range, and output behavior, refer to the WT18 documentation and the model suffix specifications, since variations like the S14 version determine the precise characteristics of this particular part.
