With a lightweight design and a dual pack offering, it's perfect for both hobbyists and professionals looking to enhance their projects. ## Description Description: Type: KY-040 Rotary Decoder Encoder. Operating Voltage: 5V. One round number of pulse: 20. Width: 19mm/0.75 Inches. Length: 30mm/ 1.18 Inches. Height: 28mm/1.10 Inches. Material of Knob Cap: Aluminium Alloy. Diameter of Knob Cap: 14mm/ 0.55 Inches. Height of Knob Cap: 17mm/ 0.67Inches. Package:2 PCS. Pin description: CLK - equivalent to output A in regular encoder. DT - equivalent to output B in regular encoder. GND - equivalent to output C in regular encoder. SW - reset switch. + (VCC) - positive supply to the unit. The KY-040 rotary encoder is a 360 degree rotary input device (i.e. a control knob) that provides an indication of how much the knob has been rotated AND which direction it is rotating in. It is a great device for stepper and servo motor control. You can also use it to control devices like digital potentiometers. It is ideal for navigating menus on a display or taking inputs such as numbers or text characters. The range of input can be easily defined and mapped in software. A push button switch is built into this encoder. If you push on the shaft, the normally open switch "SW" will close. This can be used as an On/Off switch, to change control functions, ranges, selecting a menu item or entering a number. The "D" shaft of the encoder can be fitted with a knob for using it in a product. ## Features - Type: KY-040 Rotary Decoder Encoder. - Operating Voltage: 5V. One round number of pulse: 20. - Size: 30x19x28mm/1.18x0.75x1.10 Inches(LxWxH). Package:2 PCS. - Unlike rotary potentiometer count, the rotation counts are not limited. - With the button on the rotary encoder can be reset to its initial state, that starts counting from 0. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand Name | Tegg | | Package Dimensions | 8.89 x 6.6 x 3.3 cm; 91 g | | Item model number | KY040-WKC-2 | | Manufacturer | Tegg | | Item Weight | 91 g | ## Images ![2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - Image 1](https://m.media-amazon.com/images/I/61w21cBTrZL.jpg) ![2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - Image 2](https://m.media-amazon.com/images/I/61XVhl7HZAL.jpg) ![2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - Image 3](https://m.media-amazon.com/images/I/611n6DzJbDL.jpg) ![2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - Image 4](https://m.media-amazon.com/images/I/61ZzU89emTL.jpg) ![2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - Image 5](https://m.media-amazon.com/images/I/6142Y-PCNEL.jpg) ## Frequently Bought Together - Tegg 2 PCS KY-040 360 Degree Rotary Encoder Module Brick Sensor clickable Switch with Knob Cap for Arduino - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - EDGELEC 120pcs Breadboard Jumper Wires 10cm 15cm 20cm 30cm 40cm 50 cm 100cm Wire Length Optional Dupont Cable Assorted Kit Male to Female Male to Male Female to Female Multicolored Ribbon Cables --- ## 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.ni/products/464236781-2-pcs-ky-040-360-degree-rotary-encoder-module-brick](https://www.desertcart.ni/products/464236781-2-pcs-ky-040-360-degree-rotary-encoder-module-brick) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-04-23*
