Omron EE-SPZ301-A Photomicrosensor
Omron EE-SPZ301-A is a retro-reflective photomicrosensor designed for target sensing across a specified distance of 200 mm. Its optical arrangement sends light along the sensing path and evaluates the returned signal, allowing changes in that path to control the NPN switching condition. Dark-ON operation defines the output response, while the sensor operates from 5 to 24 VDC. Average current consumption is specified at 15 mA maximum and peak consumption at 50 mA maximum. The output supports up to 80 mA load current, while a special connector provides the electrical interface. A red indicator supplies visual operating status. The EE-SPZ301-A provides longer-range sensing within the 200 mm retro-reflective sensor range across Omron Sensor Products.

The Omron EE-SPZ301-A Photomicrosensor uses retro-reflective sensing across a specified 200 mm distance. The optical arrangement relies on light returning along the retro-reflective path, and an object entering that path changes the signal received by the sensor. The model operates from 5 to 24 VDC and provides an NPN output with Dark-ON switching. Average current consumption is specified at 15 mA max., while peak current reaches 50 mA. The output supports up to 80 mA load current, with residual voltage stated as 1.0 V max. at an 80 mA load and 0.4 V max. at 10 mA. A red light indicator provides visual operating status, while a special connector supports electrical connection. The supplied tabular specifications do not identify the reflector type or optical wavelength, so these details are not added here.
The EE-SPZ301-A uses polycarbonate for both its case and lens and is specified for operation from -10°C to 55°C. Storage temperature extends from -25°C to 65°C, while operating humidity covers 5% to 85%. Its stated vibration resistance is 10 to 55 Hz at 1.5 mm double amplitude for two hours in each X, Y, and Z direction, while shock resistance is 500 m/s² three times along each axis. The enclosure carries an IP50 rating. This configuration suits applications requiring a 200 mm retro-reflective path together with NPN Dark-ON switching and connector-based wiring. For a related 200 mm EE-SPZ model using Light-ON operation instead, refer to the Omron EE-SPZ401-A.
