The Omron EE-SX772R 2M is a compact, slot-type photomicrosensor designed for precise object detection in tight industrial spaces. Featuring a through-beam configuration with a 5 mm slot width, this model accurately detects opaque objects as small as 2 × 0.8 mm. Its integrated GaAs infrared LED (940 nm) ensures high detection accuracy, and the T-shaped housing allows easy installation on circuit boards, production lines, or sensor brackets.
This sensor supports a supply voltage of 5 to 24 VDC with up to 10% ripple (p-p), and provides a PNP open collector output. It operates in Dark-ON mode, which triggers an output signal when light is blocked. Designed for minimal power consumption, the EE-SX772R 2M draws only 12 mA (max), making it ideal for embedded systems or energy-sensitive automation environments.
The unit includes a clear red LED indicator that activates when light is not incident on the receiver, simplifying alignment and diagnostics during setup. Its 2-meter pre-wired slim cable supports streamlined wiring in compact control panels or device assemblies. With output short-circuit protection built in, this sensor ensures safe operation even in fault conditions.
The EE-SX772R 2M operates reliably in a temperature range from −25°C to 55°C and withstands storage temperatures down to −30°C. It is tested to resist vibration (10–2,000 Hz, 100 m/s²) and shock (500 m/s², 3 times in each axis), making it suitable for use in dynamic or high-speed systems. The sensor is sealed to IP64 protection according to IEC60529, ensuring resistance to dust and light splashing water.
Its housing is constructed from high-quality PBT (polybutylene terephthalate), offering dimensional stability and electrical insulation. Compact, accurate, and easy to wire, the Omron EE-SX772R 2M is an excellent choice for applications such as printer mechanisms, labeling systems, small conveyors, or electronics assembly lines.
