M5 LTD-05NO Visible Laser Diffuse Photoelectric Switch - 10-30V DC, 50-100mm Range

The M5 LTD-05NO provides an NPN open-collector (sinking) output. This means the output transistor switches the signal line to ground (0V) when an object is detected. You must connect your load (e.g., a PLC input, relay coil, or indicator LED with a series resistor) between your positive supply voltage (within the sensor's 10-30V range) and the sensor's output wire.

Connect the brown wire to your positive DC supply voltage (10-30V), the blue wire to the negative/common ground (0V), and the black wire is the NPN output signal. Ensure your load is connected between the positive supply and the black output wire. Always observe correct polarity. The integrated visible laser simplifies alignment; point it at the target surface within the 50-100mm range.

As a diffuse reflective sensor, detection reliability depends on the object's ability to scatter the laser light back to the receiver. Transparent objects (like clear glass) or highly reflective, mirror-like surfaces may not provide sufficient diffuse reflection and could cause unreliable detection. For such materials, a through-beam or retro-reflective sensor configuration is recommended.

The 120Hz operating frequency defines the sensor's maximum response speed, allowing it to update its output state up to 120 times per second. This enables the detection of fast-moving or rapidly passing objects, making it suitable for high-speed counting applications on production lines where objects are closely spaced.

No. The specified operating temperature range is 0°C to 50°C, and there is no stated IP (Ingress Protection) rating for water or dust resistance. The sensor is designed for indoor, controlled environments such as factory floors, machinery enclosures, or laboratory equipment. Exposure to moisture, dust, or temperatures outside its rated range can damage the electronics.
