Ultrasonic sensor UNAM 12P8910/S14OD, 0...40 mm, PNP NO/NC, M12

UNAM 12P8910/S14OD is a Baumer high-speed ultrasonic proximity sensor in an M12 threaded housing with a 0...40 mm operating range. Response and release time are below 1.3 ms, and the switching frequency reaches 225 Hz.

• Accuracy: repeatability < 0.5 mm; hysteresis typ. 4 % Sde; temperature drift < 0.18 % Sde/K
• Sensing distance: 0...40 mm, set by external teach-in (white wire); sonic frequency 380 kHz
• Output: PNP, NO/NC programmable, up to 200 mA; voltage drop < 2 V DC
• Supply: 12...30 V DC, consumption up to 35 mA; short-circuit and reverse-polarity protected
• Housing: M12 x 1 nickel-plated brass cylinder, 100 mm long
• Environment: IP67, operating temperature -10...+60 °C
• Connection: M12 connector

The short operating range and fast response suit detection of small objects in fast cycled motion, where an optical sensor fails on transparent or glossy surfaces. The switching point is taught by connecting the teach-in wire; the green LED flashes when a target is inside the range, which helps with alignment.
