Description

The PONO WTA20-20M utilizes time-of-flight (ToF) laser ranging technology with a 905nm wavelength to deliver precise, non-contact distance measurements. Its high 2000Hz sampling rate enables rapid feedback for fast-moving targets in automation and robotics. The sensor’s advanced optical design provides exceptional immunity to ambient light up to 100,000 lux, ensuring reliable operation in both indoor and outdoor settings.

Engineered for industrial environments, the sensor features a sealed IP65 housing that protects against dust and water jets. The low 1.5W power consumption and wide 12-30VDC operating voltage range make it suitable for integration into a variety of control systems, from mobile robots to fixed automation lines. The RS485 interface allows for robust, noise-immune communication over extended distances, supporting standard industrial protocols.

Frequently Asked Questions

What is the communication protocol and how do I wire the RS485 interface?

The sensor uses a standard RS485 half-duplex interface. You will need to connect the A (D+) and B (D-) differential data lines to your host controller's RS485 transceiver, along with the power (12-30VDC) and ground wires. The specific data format (e.g., Modbus RTU) must be configured on your PLC or microcontroller to match the sensor's default or user-set protocol.

What is the operating voltage range and typical power consumption?

The sensor operates from a wide 12 to 30VDC supply. At a nominal 24V, its average current consumption is approximately 46mA, resulting in a typical power draw of about 1.1W. The peak current can reach 100mA during laser pulse emission. Ensure your power supply can provide stable voltage within this range.

How does ambient light affect the sensor's performance?

The sensor is designed with high ambient light immunity up to 100,000 lux (100Klux). This means it can operate reliably in brightly lit indoor environments or under direct sunlight without significant performance degradation. The 905nm laser wavelength and optical filtering help reject broad-spectrum ambient light interference.

What is the meaning of 'Class 1' laser safety rating?

A 'Class 1' laser product is considered eye-safe under all conditions of normal use, as per the IEC 60825-1 safety standard. The 905nm laser emitter in the WTA20-20M is inherently low-power and enclosed, posing no radiation hazard during operation, installation, or maintenance, requiring no special laser safety precautions.

Can this sensor be used outdoors or in wet conditions?

Yes, the sensor's IP65 rating indicates it is dust-tight and protected against water jets from any direction. This makes it suitable for outdoor use and in industrial environments where it may be exposed to rain, wash-downs, or high humidity. However, it is not submersible and should not be installed in standing water.
