Allen-Bradley 42JT-F5LET1-P4 Photoelectric Sensor

The Allen-Bradley 42JT-F5LET1-P4 VisiSight Color Mark Photoelectric Sensor is a compact 12 mm rectangular color-mark detector that uses a white LED light source and IO-Link communication for easy digital integration on packaging and assembly lines. It offers DC operation with either Light-Operate (LO) or Dark-Operate (DO) mode, a Push-Pull output configurable for NPN/PNP, and a 4-pin Pico QD connector for reliable wiring. Teaching is done via a front-panel push button or remote teach, with a sensing range of 12 mm (0.47 in.) and optical tolerance of ±2.5 mm. The IO-Link enabled sensor also supports robust industrial environments with IP67 and IP69K ingress protection and operating temperature from -20 to +60 C. This model, part of the VisiSight family, is designed for detecting color marks on labels or features, providing a clear, binary signal when a color-mark is detected within range, making it suitable for print registration, label verification, or feature-sensing tasks in automated lines.
