## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=PRT-18582:1` (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/PRT-18582:1.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 IR proximity contactless button makes for a good replacement for typical push buttons in situations where touching the button isn't required or desirable (especially in this day and age). This button includes a built in microcontroller to handle interference or noise, a red/blue status LED gives the user visual feedback that a "touch" has been registered, and two potentiometers on the back of the device allow you to adjust the read range from 3-15cm and adjust the "open time" from 0.5 to 20 seconds. All this is encased in a Fire/IR resistant package that easily mounts through most panels and surfaces.

- Built-in micro controller for decoding infrared signal to avoid interference from the noise.
- Bi-color status LED (Power on: Red/ Proximity: Blue).
- Adjustable proximity range: 3~15cm (Default: 15 cm)
- Support adjustable opening time 0.5~20 Sec. (Default: 0.5 Sec.) or latched ON or OFF output.
- Polycarbonate fire & UV proof material enclosure.
- 39.7mm Diameter (full dimensions in datasheet)
