SICK AG VL-18-3P3640 Photoelectric Sensor 4 Pin

SICK VL18-3P3640 is a retroreflective photoelectric sensor from SICK AG, designed in the compact VL18 18 mm barrel form factor and equipped with a 4‑pin connector for straightforward wiring on industrial automation lines. As a retroreflective device, it emits light toward a reflector and detects the return beam when a target interrupts or reflects the light, making it well suited for sensing flat or glossy parts, labels, or packaging on conveyors and in machine-automation setups. The VL18-3P3640 belongs to SICK’s V18 family of compact sensors, which emphasizes reliable operation in tight spaces, with a four‑pin interface that supports standard field wiring for control systems and logic signals. This specific model is identified by the 4‑pin configuration and barrel-mounted housing, aligning with distributor listings that document VL18‑3P3640 as a 4‑pin retroreflective SICK sensor in the VL18 series. For exact electrical specifications, sensing range, timers, and environmental ratings, refer to the official VL18-3P3640 data sheet and manufacturer listings.
