Good sensor, careful alignment
Works as expected but you need to align the beam precisely. Good value.

Solid build quality
Plastic housing is lightweight but durable. Cables could be longer.

Arduino Project Success
Integrated easily with my Arduino counter project. Voltage range is flexible.
5 FAQ
Q: What is the maximum detection frequency?
A: It supports up to 2kHz depending on the object size and speed.
Q: Is the output normally open or closed?
A: The output state changes when the beam is blocked. It is configurable via wiring.
Q: Can I use this outdoors?
A: This module is designed for indoor industrial use. It is not weatherproof.
Q: Can this run on 3.3V logic?
A: The module operates on 5-24V, but output is open collector so it interfaces with 3.3V logic easily.
Q: Does it come with mounting screws?
A: Mounting holes are M3 standard, but screws are not included in the package.
