Review: It won't work if you don't adjust the sensitivity! - I got a panel tach that came with a magnetic pick up. I made sure to match specs (npn no) same as that one and used this instead. It works brilliantly! Best part is I use it for indoor blower speeds and you don't even have to paint the blower metal black. Just stick on the reflective tape and go! I verified accuracy with a quality tool and it is spot on, only off by .4 rpms when at 180. I have used it up to 1100 rpms and it's able to go much higher. The whole project cost me like $30.00 as I used a transformer I had kicking around and a metal box to put the components and display in, as well as a power cord. Review: Works well - Good construction, lightweight and easy to install. Works well for my application. ## Features - Inductive type: diffuse reflection; Induction distance: 30cm adjustable; Working voltage: 6-36V both can The positive, blue, black, black, black. - Product Name : Photoelectric Switch;Sending Light : Infrared Rays;Model : E3F-DS30C4;Detection Way : Diffuse Type Inductive type: diffuse reflection; Induction distance: 30cm adjustable; - Output Form : 3 Wires;Voltage : DC 6-36V;Output State : NPN NO - Body Size : 2.3x 6.9cm/0.9" x 2.7'' (Max.D*L); Thread diameter: 18mm; Material : Plastic, Alloy;Color : Black, Orange - Cable Length : 1.2m / 47'';Weight : 57g;Package Content : 1 x Photoelectric Switch ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.2 out of 5 stars 45 Reviews | ## Images ![Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - Image 1](https://m.media-amazon.com/images/I/61nBFxkDEiL.jpg) ![Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - Image 2](https://m.media-amazon.com/images/I/71qQlgQs97L.jpg) ![Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - Image 3](https://m.media-amazon.com/images/I/61nxzlWkXZL.jpg) ![Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - Image 4](https://m.media-amazon.com/images/I/71vh162jExL.jpg) ![Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - Image 5](https://m.media-amazon.com/images/I/61ns+ZXQoaL.jpg) ## Questions & Answers **Q: What is the maximum rpm this sensor can handle? fyi, i need something that can go as high as 40,000 rpm.** A: The specs state 2.5 ms reset time. According to my calculations, 40,000 rpm with one reflective strip equates to a reset time of less than 1.5 ms. Therefore it would not be expected to work. **Q: Pero traslucidas podra ver es para vidrio sin color** A: Action indication: red LED Detectable objects: ≧Φ18mm opaque objects Detection distance: 30cm Distance adjustable range: 5-30cm **Q: Does the npn no version need a pull up or pull down resistor? what value?** A: This is just an inductive switch and has no other effect **Q: What is the adjustment screw for? is the 30cm mentioned the minimum or maximum range? what does the red led tell you?** A: The maximum sensing distance is 30cm, the red probe is PMMA light transmission mirror, the response is more sensitive ## Customer Reviews ### ⭐⭐⭐⭐⭐ It won't work if you don't adjust the sensitivity! *by C***E on September 7, 2019* I got a panel tach that came with a magnetic pick up.

Works well for my application. ### ⭐⭐⭐⭐⭐ Dust collector sensor. *by A***. on November 13, 2021* Worked better than a more expensive sensor on DIY dust level sensor. I made a level sensor on my Oneida dust deputy that sits on my festool vacuum. This sensor was perfect. I was able to adjust the distance to the 4" I needed with room to adjust closer or farther. My gamble paid off and I purchased 2 more for spare parts just in case. ## Frequently Bought Together - Taiss/photoelectric Sensor 30 cm Adjustable M18 Diffuse photoelectric Switch Sensor Optical Three Lines NPN NO (Normally Open) Proximity Switch 6-36VDC E3F-DS30C4 - 24V 1A AC Adapter Power Supply 100-240V AC to DC 24Volts 1A 24W Converter Transformer Switching Power Supply with 5.5mmx2.5mm Plug for LED Strip Light CCTV Camera DC Pump, Black - Baomain Warning Lamp LTE-5061 Industrial DC 24V LED Flash Strobe Light Red --- ## 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.uk/products/71018398-taiss-photoelectric-sensor-30-cm-adjustable-m18-diffuse-photoelectric-switch](https://www.desertcart.co.uk/products/71018398-taiss-photoelectric-sensor-30-cm-adjustable-m18-diffuse-photoelectric-switch) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
