Telemecanique XX518A3PAM12 is a diffuse ultrasonic sensor of the XX5 series in the XX range, with a plastic M18 body. Its nominal sensing distance is 0.5 m, adjustable with a remote teach pushbutton; the sensing range is 0.051–0.508 m and the blind zone 0–51 mm. Working at a 300 kHz transmission frequency with a 6° beam angle, it offers 1.27 % repeat accuracy and a maximum differential travel of 2.5 mm. It detects a Ø2.5 mm cylinder at 0.15 m and tolerates a ±7° deviation of the object from 90°.
The 3-wire PNP 1 NO output switches up to 100 mA with overload and short-circuit protection; maximum voltage drop is 1 V and switching frequency up to 40 Hz. The 12–24 V DC rated supply (10–28 V DC limits) is reverse-polarity protected and current consumption is 40 mA. Connection is by an M12 4-pin male connector; the white wire is the teach input. The sensor has a Valox enclosure, epoxy front face, M18 x 1 thread, 43 mm threaded length and 0.033 kg weight; protection is IP67 and operating temperature -20 – +65 °C.

Is this ultrasonic sensor right for your application?
Share the object to be detected or the level to be measured (liquid, granules, transparent or coloured surface), the required sensing range, the mounting conditions (adjacent sensors, inclined surface), ambient conditions (dust, vapour, temperature) and your PLC input (analogue 4–20 mA / 0–10 V, PNP/NPN); let’s select the right ultrasonic sensor together.
