Industrial ATC 7603A R04 N22 NX Photoelectric Sensor

ATC 3-7643AR04N22NX is a cylindrical retroreflective photoelectric sensor from ATC Automatic Timing & Controls, part of the 7640 Series designed for compact, reliable object detection in industrial environments. In retroreflective configurations, the sensor is paired with a fixed reflector to create a short-range sensing zone that detects the presence or absence of reflective targets on conveyors, packaging lines, and automated assemblies. The model designation places it within ATC’s NX-configured lineup, reflecting ATC’s approach to modular, rugged photoelectric sensing in a small-diameter package that fits tight mounting spaces. This sensor is built to endure typical factory conditions while delivering dependable optical performance in continuous production. For installation, alignment of the reflector and careful consideration of ambient light conditions are important, along with wiring to a compatible controller or PLC using the sensor’s standard output arrangement as defined by ATC. While exact electrical characteristics and pinouts vary by configuration, the 7640 series is known for a compact footprint and straightforward integration into standard industrial control systems. For precise electrical specs, target distance (sensing range), response time, and connection details for the 3-7643AR04N22NX variant, consult the official ATC datasheet and product documentation.
