The Keyence PZ-V31 is a rectangular photoelectric sensor featuring retroreflective operation, a built-in amplifier, and a 2-meter cable. It is equipped with a 7-segment, 3-digit LED digital monitor. This sensor is part of the PZ-V series and is an intelligent reflective type with an NPN output. Its detection distance ranges from 5 to 300 mm, and it uses a red LED as its light source. The response time is 1 ms, and it supports both LIGHT-ON and DARK-ON operating modes. Status indication is provided by an orange LED for the output and a green LED for stable operation. The control output is NPN with an open collector, rated for up to 100 mA and 24 V, with a residual voltage of up to 1 V. The sensor operates on a supply voltage of 12 to 24 V DC and consumes up to 37 mA. It has a protection class of IP67 and can function in ambient temperatures between -20 and +55 °C. The included cable is 2 meters long, and the sensor weighs 55 g.
