The Autonics PRD12-8DP2 is a non-flush sensor with a sensing side diameter of Ø12 mm and a sensing distance of 8 mm. It provides a hysteresis of up to 10% of the sensing distance and is designed for a standard sensing target of 25 × 25 × 1 mm iron. The unit operates from 12 to 24 VDC with ripple tolerance and 10 to 30 VDC, drawing up to 10 mA, and offers a control output of up to 200 mA with a residual voltage of up to 1.5 V. An operation indicator LED glows red to show status. It includes protection circuits for surge, short or overcurrent, and reverse polarity, with insulation resistance of at least 50 MΩ at 500 VDC and a dielectric strength of 1,500 VAC 50/60 Hz for 1 minute. Vibration tolerance is 1.0 mm at 10–55 Hz in X, Y, Z directions for 2 hours, and shock tolerance is 50 G with three shocks per axis. The operating environment ranges from -25 to 70 °C, with storage from -30 to 80 °C, and humidity from 35 to 95% RH. The enclosure is IP67 protected, and it uses a cable connection with a standard black PVC cable. The housing comprises nickel-plated brass for the case/nut (Ø8 mm sensing side) with a SUS303 connector case, a nickel-plated iron washer, and sensing side PBT. Packaged weight is about 74 g (typical 62 g).
