The Omron EE-SX772 2M is a slim, high-precision slot-type photomicrosensor designed for miniature object detection in automated machinery and compact assemblies. Featuring a through-beam optical system built into a T-shaped body, this sensor offers a fixed 5 mm slot width and can detect opaque objects as small as 2 × 0.8 mm. Its GaAs infrared LED light source (940 nm) ensures stable and accurate sensing, making it suitable for applications such as part detection, edge counting, or small-component presence confirmation.
The sensor operates on 5 to 24 VDC ( ripple), and provides an NPN open collector output with a Dark-ON switching logic. It comes with a pre-wired 2-meter cable and consumes only 12 mA max., making it ideal for space-saving installations and low-power systems. The built-in red light indicator responds to incident light, simplifying setup and operational diagnostics.
Constructed from durable polybutylene terephthalate (PBT), the EE-SX772 2M withstands harsh industrial environments while maintaining a lightweight profile. It operates reliably in temperatures from –25°C to 55°C and humidity from 5% to 85% without condensation. The sensor is resistant to vibration (10–2000 Hz, 1.5 mm double amplitude, 100 m/s² peak acceleration) and shock (500 m/s²), with output short-circuit protection built in to ensure safe long-term operation.
With IP64-rated protection under IEC60529 standards, the Omron EE-SX772 2M is suitable for indoor industrial use where exposure to dust or moisture is minimal. It is frequently deployed in printers, assembly systems, packaging equipment, and light-duty automation lines where compact sensing with fast response and high repeatability is essential.
