{"product_id":"surface-mount-rotary-encoder-ec11j","title":"Surface Mount Rotary Encoder - EC11J","description":"\u003cp\u003eFor projects that need a rotary encoder but need to keep it single-sided or need to avoid interrupting traces or devices on the other side, here's an all-SMT rotary encoder! It's a high-quality 30-detents encoder from Alps, with detents and a nice feel. There's a nice smooth bushing for placement in a box.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKnob not included\u003c\/strong\u003e,\u003cspan\u003e \u003c\/span\u003ebut you can pick one up here. \u003c\/p\u003e\n\u003cp\u003eThis encoder also has a push-button built into it so you can press onto the knob to close a separate switch. One side has a 3 pad connector (ground and two coding pins) and the other side has two pads for a normally open switch. There are also 6 large mechanical pads for making a strong physical connection: best to use a ground plane with 6 open pads so that there's a solid sheet to protect against the encoding shearing off.\u003c\/p\u003e\n\u003cp\u003eRotary encoders are useful as rotation sensors or selectors and look similar to potentiometers. However they are not like potentiometers at all, so it's important to realize the difference! These rotary encoders rotate all the way around continuously and are divided up into 30 'segments'. Each segment has a clicky feeling to it, and each movement clockwise or counter-clockwise causes the two switches to open and close. There is no way to know what the current 'position' is - instead you would use a microcontroller to count how many 'clicks' left or right it has been turned. If you need to detect rotational 'position' a potentiometer would be a better choice.\u003c\/p\u003e\n\u003cp\u003e\u003ciframe width=\"560\" height=\"315\" src=\"\/\/www.youtube.com\/embed\/LlV2xzXUYgA?start=100\" title=\"YouTube video player\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"allowfullscreen\"\u003e\u003c\/iframe\u003e\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e15mm long flat shaft\u003c\/li\u003e\n\u003cli\u003e30 detents\u003c\/li\u003e\n\u003cli\u003ePress-switch travel: 1.5mm\u003c\/li\u003e\n\u003cli\u003eOperating life: 100,000 cycles\u003c\/li\u003e\n\u003cli\u003eOperating temperature range: -40℃ to +85℃\u003c\/li\u003e\n\u003cli\u003e10mA 5V DC\u003c\/li\u003e\n\u003cli\u003eOutput signal: A, B, 2-phase output\u003c\/li\u003e\n\u003cli\u003eMaximum\/minimum operating current (resistive load): 10mA\/1mA\u003c\/li\u003e\n\u003cli\u003eInsulation resistance: 100MΩ min. 250V DC\u003c\/li\u003e\n\u003cli\u003eWithstand voltage: 300V AC for 1 minute or 360V AC for 1s\u003c\/li\u003e\n\u003cli\u003eDetent torque:\n\u003cul\u003e\n\u003cli\u003e12±5mN·m (initial stage)\u003c\/li\u003e\n\u003cli\u003e10±4mN·m (after reflow)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eShaft push and pull strength: 100N\u003c\/li\u003e\n\u003cli\u003eJourney: 0.5±0.3mm\u003c\/li\u003e\n\u003cli\u003eAction force: 5±2N\u003c\/li\u003e\n\u003cli\u003eRoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDatasheet\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43643728461885,"sku":"vyp1789692729932","price":4.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0658\/9716\/8957\/files\/surface-mount-rotary-encoder---ec11j_1.jpg?v=1789692735","url":"https:\/\/laser-engraved-clasp.shop\/products\/surface-mount-rotary-encoder-ec11j","provider":"My Store","version":"1.0","type":"link"}
