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.

5 FAQ

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.
