Overview
The Allen-Bradley 42JT-C2LAT1-F4 is a compact VisiSight photoelectric sensor optimized for clear object detection in industrial control and automation systems. This unit delivers reliable sensing with a 2-meter detection range and visible red LED alignment indicator. The sensor supports both light-operate and dark-operate modes, with teachable sensitivity adjustment via push button or remote configuration. IO-Link support enables advanced diagnostics and parameter management on compatible control systems.
Key Features
- Clear Object Detection Mode — specifically tuned to detect transparent or translucent materials with minimal false triggers
- Teachable Light/Dark Operate — flexible mode selection with push-button and remote sensitivity teaching for quick field commissioning
- Autodetect PNP/NPN Output — automatically configures for source (PNP) or sink (NPN) logic, eliminating wiring errors
- IO-Link Interface — enables condition monitoring, parameter adjustment, and predictive maintenance on IO-Link-enabled controllers
- Visible Red LED — aids alignment and troubleshooting without additional test equipment
- M12 Quick-Disconnect Connector — standard 4-pin micro connector with pigtail for fast installation and replacement
