Easy to integrate
As someone new to sensors, I found this very easy to connect to my Arduino. The documentation online is helpful, and the sensor responds instantly to magnets.

Works as advertised
Does exactly what it says on the tin. The switching point is sharp and repeatable. Just make sure you have the correct polarity when connecting it.

Reliable replacement part
Bought these to replace failing sensors on a conveyor belt system. They have been running 24/7 for three months without any issues. Very satisfied with the durability.

Perfect for my CNC project
This sensor works flawlessly as a limit switch on my homemade CNC router. The detection range is consistent, and the wiring was straightforward. Highly recommended for hobbyist automation.

Great for automotive applications
Used this for a custom tachometer setup. It handles the vibration and heat under the hood better than expected. Excellent product.

Good value, sturdy build
Solid construction and reliable performance. I deducted one star because the cable could be a bit longer for some industrial setups, but otherwise, it's a great component for the price.
Q: Does it come with mounting hardware?
A: Yes, the package includes the sensor with pre-drilled mounting holes and a set of screws for easy installation.
Q: Is this sensor PNP or NPN output?
A: The NJK-5002C model features an NPN open collector output. Please check your controller requirements before purchasing.
Q: Can this detect non-magnetic metals like aluminum?
A: No, this is a Hall Effect sensor designed specifically to detect magnetic fields. It will not detect non-magnetic materials unless a magnet is attached to them.
Q: What is the maximum voltage this can handle?
A: This sensor operates safely within a DC voltage range of 6V to 36V. Exceeding 36V may damage the internal circuitry.
Q: Is the cable length customizable?
A: The standard unit comes with a 2-meter cable. We do not offer custom lengths directly, but the wires can be extended using standard electrical practices.
