The Baumer UNAR 18N6903/S14G 10161023 is a chemically robust ultrasonic sensor designed for precise distance measurement within a range of 100 to 1000 mm. It features a repeat accuracy of 0.5 mm and a temperature drift of less than 0.18% Sde/K, ensuring reliable performance under varying conditions. The sensor operates with a quick response and release time of less than 50 ms and utilizes a high sonic frequency of 240 kHz. It includes a teach-in adjustment for easy setup and a target indication flashing for better alignment, along with a green LED output indicator. This model is equipped with an NPN make function output circuit and can handle an output current of up to 200 mA. It supports a voltage supply range of 12 to 30 VDC and includes safety features such as short circuit and reverse polarity protection. The cylindrical stainless steel housing, coated with Parylene and equipped with an FFKM O-ring, withstands pressures up to 6 bar and is durable for over 20,000 cycles. The sensor has a protection class of IP 67, making it suitable for harsh environments. It connects via an M12 connector and operates within a temperature range of 0 to +60 °C.
