Overview
The Allen-Bradley R7KJS-T9MPA1-F4 is a Series 7000 sensor replacement kit designed for photoelectric detection applications requiring transmitted beam technology. This complete kit includes the 42JS sensor element, mounting bracket, visible red LED indicator, and a 4-pin M12 (DC Micro) quick-disconnect connector on a 150 mm pigtail. The unit operates with PNP logic output and supports both light-operate (L.O.) and dark-operate (D.O.) modes through an onboard teach button.

Compatibility & Replacements
The R7KJS-T9MPA1-F4 is part of Allen-Bradley’s Series 7000 sensor replacement kit family. Related kit options include models with different beam types (diffuse, retroreflective) and output configurations (NPN variants). For connector alternatives, the -F4 suffix indicates M12 quick-disconnect; compatible suffix options include -A2 (2 m cable, no QD connector) and -Y4 (M8 pico connector). Verify sensor output type (PNP vs. NPN) and detection method before substitution to ensure PLC compatibility.
