## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09233:1` (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/CE09233:1.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

This sensor is perfect for robotics projects.

Inside the U-shaped plastic housing, there is an infrared LED and photodiode, an object will break the beam allowing it to be detected.

The SIG wire is pulled low (GND) without anything in the beam of the sensor, when broken the signal goes high (Vcc).

We've found that fast-moving or transparent objects doesn't fully turn on the sensor, be sure to test beforehand!

### Specifications

- Supply Voltage: 3.3 - 5 V
- Output: 0-Vcc, Logic HIGH (Vcc) When the beam is broken, pulled down otherwise
- Dimensions: 36 x 11 mm
- Mounting Holes: 3mm diameter, 38mm apart
- Space inside sensor: 4 x 8 mm (WxH)
- Connector: JST-XH
