Generic M4 FTD-04NO Laser Micro Diffuse Photoelectric Switch - 70mm Range, 10-30V DC

The sensor provides an NPN open collector output (normally open configuration). It has three wires: Brown for DC+ (10-30V), Blue for DC- (GND), and Black for the output signal. The output sinks current to ground when an object is detected.

Yes, due to its diffuse reflection principle using an invisible laser, it can detect a wide variety of surfaces, including transparent, glossy, or matte objects. The detection reliability depends on the object's ability to scatter light back to the receiver within the 70mm range.

The 120Hz operating frequency defines the maximum rate at which the sensor can detect objects passing by. The built-in delay and expansion functions allow you to set an on-delay or off-delay, which helps debounce the signal, ignore brief interruptions, or provide a sustained output pulse for reliable PLC or controller input.

Mount the sensor using its M4 threads into a tapped hole or a matching nut. For diffuse reflective mode, no separate reflector is needed. Simply aim the sensor's front face towards the target area. The invisible beam requires no visual alignment; correct positioning is confirmed by the output triggering when an object enters the 70mm detection zone.
