Description

The M3 LTD-03NO photoelectric switch employs a diffuse-reflective sensing principle, where its integrated visible red laser emitter and receiver detect objects based on the reflection of light. This method allows for the detection of a wide variety of materials and surface colors without requiring a separate reflector. The integrated synchronous loop gate circuit provides stable, anti-interference operation.

Housed in a durable, threaded M3 stainless steel pipe, this sensor is built for longevity in industrial settings. It features a standard NPN open-collector output capable of sinking up to 150mA, making it directly compatible with PLC inputs, relays, and other control circuits. Its compact form factor and threaded design facilitate easy integration into machinery, assembly lines, and automated systems.

Key Features

  • Diffuse-Reflective Visible Laser Sensing for versatile object detection.
  • Wide-Range 10-30V DC Supply Voltage compatibility with 12V and 24V industrial systems.
  • High-Speed 120Hz Switching Frequency enables rapid part counting and positioning.
  • Durable M3 Threaded Stainless Steel Housing ensures corrosion resistance and mechanical strength.
  • NPN Open-Collector Output (150mA max) for direct interface with digital inputs.
  • Low 9mA No-Load Current consumption for energy-efficient operation.
  • Stable Operation across a 0°C to 50°C temperature range.

Frequently Asked Questions

What is the output type of the M3 LTD-03NO sensor?

The sensor provides an NPN open-collector output. This means the output pin acts as a switch to ground (0V) when an object is detected. It can sink up to 150mA, allowing it to directly drive relays, PLC digital inputs, or indicator LEDs when connected with a proper pull-up resistor to the positive supply voltage.

What power supply voltage does this laser switch require?

It operates on a wide-range DC voltage from 10V to 30V. This makes it compatible with common industrial power standards like 12V and 24V DC. Ensure your power source can provide stable voltage within this range and account for the sensor's low 9mA no-load current consumption.

How do I wire and install the M3 LTD-03NO?

Connection is made via the integrated screw terminals. Typically, you connect the brown wire to DC+, the blue wire to DC-, and the black wire is the NPN output. For mounting, use the M3 threaded stainless steel body to screw it directly into a pre-tapped hole or a suitable nut on your equipment, ensuring the sensing face is properly oriented toward the detection area.

Can it detect transparent or shiny objects?

As a diffuse-reflective sensor, it relies on light scattering back from the object's surface. Highly transparent or specularly reflective (mirror-like) surfaces may not scatter enough light back to the receiver, potentially causing detection issues. For best results, test with your specific target material at the intended sensing distance.
