## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0116:1` (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/SEN0116:1.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

Introduction

 This encoder is matched with 2wd miniQ Robot chassis. AB two-phase pulse wave,measured by two infrared reflective sensor. These two sensor pulse waveform is close to a phase difference of 90 degrees, through the AB two-phase lead and lag of the waveform judged wheel forward rotation or the reverse. You can install it on the motor bracket or mini robot chassis to do the PID and position control. Note: Please short current R4 when working in 3.3V Specification - Working Voltage:3.3V or 5V
- Working Current:<14mA @5V
- Pulse Output:12 per revolution
- Compatibility:42mm x 19mm wheel
