This non‑contact ultrasonic sensor operates on 9–30 V DC (≤2.4 W) with NPN output, offering a 30–250 mm sensing range (350 mm limit), ≥0.18 mm resolution, ±0.15 % repeat accuracy, and ±1 % measurement accuracy. With temperature compensation, 32 ms response time, IP65/IP67 protection, and M30 threaded brass housing, it reliably detects natural solid objects in industrial positioning and fill‑level monitoring.
A: The blind zone for this non‑contact ultrasonic sensor is 0-30 mm, implicitly defined by the sensing range starting at 30 mm. Any object entering this zone will be too close for the sensor to distinguish the ultrasonic echo from the transmitted pulse, resulting in invalid or erratic output. During installation, ensure the closest possible target position never falls below 30 mm—adding a 5–10 mm safety margin is highly recommended.
A: Yes, this non‑contact ultrasonic sensor can withstand short‑term immersion (IP67 = 1 meter for 30 minutes), thanks to its robust nickel‑plated brass housing and sealed M12 connector. However, special attention is required for the transducer face, which is made of PUR foam/epoxy/glass. This foam surface absorbs water and can form droplets that severely attenuate the ultrasonic signal. For wet environments, always mount the sensor with the transducer facing downward so water can drip off naturally. If the sensor is accidentally immersed, wipe the transducer face dry before resuming critical measurements.
A: This non‑contact ultrasonic sensor defines two critical distance thresholds: Sensing range = 30-250 mm : This is the guaranteed accuracy zone. Within this interval, the specified ±1% measurement accuracy and ±0.15% repeat accuracy are fully valid. Limit = 350 mm : This is the maximum detection distance where the sensor can still perceive a target, but measurements beyond 250 mm are no longer accurate—they should be treated as a simple presence/absence flag rather than a precise distance value. For reliable readings, always keep your target between 30mm and 250mm.
