Using them as non-contact end switches for a robot. They work very well with an arduino. Review: DOA or wired incorrectly - The diagram on the sticker (attached to the cord) doesn't match how it functions. After getting the LED indicator to light (and change when a magnet is near), it seems there's only a tiny spot about 7mm down one side that actually triggers the sensor. When triggered, it only closes the circuit around 5-10% of the time (and that's with the understanding that hall effect sensors do need a magnet, not 'metal' as described). My best guess is that it needs more than the max of 5V+20mA an arduino can deliver, even though it lists 5V within the spec and only a max current. ## Features - ✹✹ Model: NJK-5002C Supply voltage : 5-30VDC; Detection distance :10mm (effective detection distance 0-10mm) ; Load current :150MA (no more than). - ✹✹ Thread Diameter: 12MM ; thread length: 32MM；Load current :150MA (no more than). - ✹✹ Output : NPN three lines Output state normally open (NO). - ✹✹ Detect objects: metal material; Product Material: Metal; Parts: Copper plastic components; PBT External leads:1.2m (standard, others according to customer requirements); Output indication:LED (red). - ✹✹ Package Content : 2 x Hall Effect Sensor. ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #655,923 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #472 in Inductive Proximity Sensors | | Customer Reviews | 3.7 out of 5 stars 24 Reviews | ## Images ![2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - Image 1](https://m.media-amazon.com/images/I/61ny7svIBzL.jpg) ![2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - Image 2](https://m.media-amazon.com/images/I/614J6068wOL.jpg) ![2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - Image 3](https://m.media-amazon.com/images/I/51kJ9E0a5XL.jpg) ![2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - Image 4](https://m.media-amazon.com/images/I/51dLAvebHbL.jpg) ![2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - Image 5](https://m.media-amazon.com/images/I/51W7g4FtGhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ They work great! *by A***R on September 26, 2020* Very pleased with my purchase. Using them as non-contact end switches for a robot. They work very well with an arduino. ### ⭐ DOA or wired incorrectly *by B***N on August 24, 2021* The diagram on the sticker (attached to the cord) doesn't match how it functions. After getting the LED indicator to light (and change when a magnet is near), it seems there's only a tiny spot about 7mm down one side that actually triggers the sensor.

(More chinese junk from amazon) would have returned but needed the ones that worked and had to cut wire to fit. My loss amazons gain, again. ## Frequently Bought Together - 2PCS DC5-30V NJK-5002C 10mm Hall Effect Switch Proximity Sensor Inductive Switch NPN NO (Normally Open) - HiLetgo 2pcs NJK-5002C Hall Effect Sensor Proximity Switch NPN 3-Wires Normally Open - AEDIKO 4pcs DC 5V Relay Module 1 Channel Relay Switch Relay Board with Optocoupler Isolation Support High or Low Level Trigger --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/179471307-2pcs-dc5-30v-njk-5002c-10mm-hall-effect-switch-proximity](https://www.desertcart.co.za/products/179471307-2pcs-dc5-30v-njk-5002c-10mm-hall-effect-switch-proximity) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-12*
