NPN /PNP /0-10v 500mm Ultrasonic Ranging Sensor Module for UC500-F36

The ultrasonic proximity switch's transmitter emits high-frequency ultrasonic waves. When these waves encounter an object, they are reflected back. The receiver captures the reflected echoes, and by measuring the time it takes for the ultrasonic waves to travel from transmission to reception, and combining this with the propagation speed of ultrasound in air, the distance between the sensor and the object can be calculated. When the distance reaches a preset threshold, the switch outputs the corresponding signal.

1. Precise and Stable Non-Contact Detection
Unaffected by Color / Transparency: 380 kHz ultrasonic echo technology can detect metals, plastics, liquids, powders, etc., overcoming the limitations of photoelectric sensors regarding color / reflectivity; detection range 50–500 mm, blind zone ≤50 mm, standard target plate 100×100 mm.
Built-in Temperature Compensation: Automatically corrects the effect of ambient temperature on sound velocity, repeatability ≤0.1% FS, response time about 50 ms, excellent linearity.
Strong Anti-Interference Capability: Insensitive to dust, light fog, or humidity; features electromagnetic compatibility (EMC) design to reduce the impact of strong interference sources such as inverters and motors.

2. Flexible Output and Power Supply Configuration
Multiple Output Options: Standard 4–20 mA analog output (-I-V1 suffix); some models support NPN/PNP switch output (NO/NC configurable, -D4/-D5 suffix), compatible with PLC/DCS systems.
Wide DC Power Supply: 10–30 V DC (typical 24 V DC industrial power), ripple ≤10%; equipped with reverse polarity protection, short-circuit / overload protection.
M12 Connector: 4/5-pin plug-and-play, quick on-site replacement, no complex wiring required.

3. Rugged and Durable Industrial Design
Protection Level IP65: Dustproof and waterproof, suitable for oily workshop conditions and washing scenarios; operating temperature -25℃~70℃, suitable for long-term operation in cold and high-temperature industrial environments.
Square Engineering Plastic Housing: High mechanical strength, convenient bolt installation, adaptable to control panel, assembly line frames, and silo sidewalls.
Multi-Sensor Synchronization: Supports ultrasonic synchronization function to avoid interference when multiple probes operate in parallel.

4. Ease of Use and Wide Applicability
Calibration-Free / Fast Setup: Factory calibrated, only need to set range and output mode on-site; some models support fine adjustment via software.
Wide Range of Applications: Silo / tank level monitoring, AGV obstacle avoidance, workpiece positioning on assembly lines, packaging machine positioning detection, sheet spacing measurement.
Low Maintenance Cost: No wear parts, only need periodic cleaning of the transducer surface, no frequent replacement of spare parts required.

1. Industrial material level / liquid level detection: monitoring the material level in storage tanks and silos
2. Object positioning and collision avoidance: workpiece positioning on automated assembly lines, AGV obstacle avoidance
3. Distance measurement: non-contact measurement of the spacing between plates and parts
4. Packaging machinery: detecting whether packaging bags / cartons are in place
