# Slim Rubber Rotary Encoder Knob - 11.5mm x 14.5mm D-Shaft

**Type:** Product page · **SKU:** ADA5093 · **Brand:** [Adafruit](https://core-electronics.com.au/brands/adafruit-australia)
**Page:** https://core-electronics.com.au/slim-rubber-rotary-encoder-knob-11-5mm-x-14-5mm-d-shaft.html ([markdown](https://core-electronics.com.au/slim-rubber-rotary-encoder-knob-11-5mm-x-14-5mm-d-shaft.html.md))

Here's a new addition to our rotary-potentiometer-knob family. This knob has a nice soft-touch feel with an arrow on it, and its much 'slimmer' than the skirted knob we have been using, so good for compact layouts.

## Pricing

- **Price:** $1.55 (inc GST) — $1.41 AUD, exc GST
- **Quantity discounts:** 10+ $1.36 (exc GST) · 50+ $1.34 (exc GST)

## Availability & dispatch

- Available with a lead time — expect dispatch between Aug 18 and Aug 24.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=ADA5093:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/ADA5093:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

Here's a new addition to Adafruit's rotary-potentiometer-knob family. This knob has a nice soft-touch feel with an arrow on it, and its much 'slimmer' than the skirted knob Adafruit have been using, so good for compact layouts.

Note: This is just the knob. [Adafruit have a breadboard-friendly rotary encoder here.](https://core-electronics.com.au/rotary-encoder-extras.html)

Rotary 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 24 '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.

**Technical Specifications**

- Dimensions: 11.5mm x 14.5mm
- Diameter: 6mm
