The Omron EE-SPW321-A is a high-precision through-beam photomicrosensor with an integrated amplifier and pre-wired cable. Designed for accurate object detection up to 300 mm, it features a 1 m cable from emitter to amplifier and a total 2 m connection length, making it easy to install in control panels and compact machines.
Operating in Dark-ON mode, the sensor uses a modulated infrared light source and outputs an NPN open collector signal. It supports up to 101 mA load current with a residual voltage of 1 V max. The red LED indicators on both the sensor and amplifier help in quick diagnostics. With an average current consumption of 30 mA and a 1 ms response time, it performs reliably in fast-paced automation setups.
Built with an ABS resin body and acrylic lens, the EE-SPW321-A offers IP64 protection and withstands harsh industrial conditions, including temperatures from -20°C to 55°C.
