Technical Overview
The Omron EE-SX972-C1 is an EE-SX97 through-beam slot-type photomicrosensor in the T-shaped, 7 mm slot center form. It has a 5 mm slot, 940 nm infrared LED, four-pole connector, and separate Light-ON and Dark-ON outputs in NPN configuration. Omron specifies a minimum opaque sensing object of 2 × 0.8 mm, 5–24 V DC supply, 21 mA maximum current and IP50 protection.

Suggested applications
Engineering suggestions require suitability checks for your installation.
1. Small-part position detection
Detect a small opaque part crossing the slot in a feeder or assembly mechanism.
Potential use
The slot geometry and separate output logic provide a discrete signal; verify target opacity, insertion path and switching margin in the actual mechanism.
5 mm slot
2 × 0.8 mm min.
940 nm
2. Compact mechanism state sensing
Monitor a moving tab or flag in a compact machine mechanism.
Potential use
Select the appropriate shape and NPN/PNP wiring, then use the Light-ON or Dark-ON output required by the controller input.
