## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=FIT0770:1` (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/FIT0770:1.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 is a background suppression photoelectric switch with 15mm-350mm adjustable detection range (can be adjusted by the knob). Its response time is only 0.5ms, fast and stable. Adopting eco-friendly and durable ABS material, the sensor detection performance is not affected by color and background, and less affected by surface roughness. Moreover, it integrates reverse current protection, over current protection and over-voltage protection, safe and reliable to use.
