UC500-L2 ultrasonic detection Proximity sensor switch for assembly line counting

The UC500-L2 ultrasonic proximity switch is a high-performance non-contact detection device. It operates on the principle of ultrasonic pulse reflection and can accurately detect solids, liquids, powders, and transparent objects, with a detection range of 35-500mm and a blind zone of 0-35mm. It features temperature compensation and can function in environments from -25°C to +70°C. With an IP65 protection rating, it is resistant to dust and oil contamination. The device supports one switch output (programmable PNP/NPN), with repeatability ≤0.1% of full scale, a response frequency ≤7Hz, an operating voltage of 10-30V DC, and short-circuit/overload protection. It is suitable for harsh industrial applications such as metallurgy, logistics, and packaging machinery, meeting the requirements for high-precision and high-reliability detection.

Working Principle

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.

Product Features

1. Rotatable / Bidirectional Probe
The probe can rotate 360° and be installed in both directions, flexibly adapting to tight spaces and different installation angles.

2. Omnidirectional Status Indication
Multicolor LEDs (green/yellow/red) allow viewing of operation/detection/fault status from any angle.

3. Highly Programmable Parameters
Switch points, window mode, normally open/normally closed, and sound cone width (wide/narrow) can all be set.
Supports multi-sensor synchronization to avoid ultrasonic interference.
Can be configured via a programming adapter or serial port.

4. Stable and Reliable Industrial Design
Built-in temperature compensation reduces the impact of temperature drift.
Resistant to dust, humidity, and light oil; unaffected by color or transparency.
Quick-install clips make on-site deployment convenient.

5. Flexible Applications
Suitable for: material/liquid level monitoring, AGV obstacle avoidance, assembly line positioning, packaging verification, and distance measurement.

application scenarios

Material level / liquid level monitoring, AGV obstacle avoidance, assembly line positioning, packaging position detection, distance measurement.
