Baumer UNAR 18I6903/S14G 10158870
Baumer
The Baumer UNAR 18I6903/S14G 10158870 is a chemically robust ultrasonic sensor designed for precise distance measurement within a range of 100 to 1000 mm. It features high repeat accuracy of 0.5 mm and a resolution of less than 0.3 mm. The sensor operates with a quick response and release time of less than 80 ms each, and minimal temperature drift. It emits at a sonic frequency of 240 kHz and includes a teach-in adjustment for easy setup. The sensor is equipped with both yellow and red LED indicators for alignment aid and target indication. It meets Ecolab standards for chemical resistance and operates on a voltage supply range of 15 to 30 VDC. The sensor supports a 4 to 20 mA current output signal and is protected against short circuits and reverse polarity. Its cylindrical stainless steel housing is durable and designed to withstand pressures up to 6 bar. The sensor is IP67 rated for protection against dust and water ingress, making it suitable for harsh environments. It connects via an M12 connector and operates within a temperature range of 0 to +60 °C.
