It will send a signal every time the beam is broken thru a 3rd wire. You do have to have a counter or something attached to accept the signal **Q: what is the switching speed of the npn receiver?** A: The actual switching time is about 2-3 microseconds on the one I've bought, but the minimum "break" time it responds to reliably seems to be at about 10 milliseconds with a 10K load resistor. you could probably increase the sensitivity with a larger load resistor but I haven't tried. **Q: This product is not infrared!. it is red laser dot. do you have one that is really infrared (>800nm)?** A: I don't have one, sorry. Issue an open ended purchase order and I will develop one just for you. Thanks. ## Frequently Bought Together - Taiss/1 Pair photoelectric Switch 0-20M Through-Beam Reflection Optical Photoelectric Beam Sensor NPN NO photoelectric Sensor Switch 6-36V Proximity Switch with Infrared Ray Beam E3F-20DNL-Z-12MM - mxuteuk 2pcs JQX-13FL DC 12V Coil 8 Pin 10A DPDT LED Indicator Electromagnetic Power Relay, with Base, with DIN Rail Slotted Aluminum - Taiss/ 1 Pair Photoelectric Sensor M18 Infrared Ray Through-Beam Reflection Optical Photoelectric Switch Sensor NPN NO 6-36VDC Proximity Switch Inductive Distance 5M with mounting Bracket E3F-5DN1 --- ## 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.com.sa/products/162777862-1-pair-photoelectric-switch-0-20m-through-beam-reflection](https://www.desertcart.com.sa/products/162777862-1-pair-photoelectric-switch-0-20m-through-beam-reflection) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-07-18*
