## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=FIT0763:1` (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/FIT0763:1.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.)

## Description

These Inductive Ring Proximity sensors are designed to detect metal objects entering or passing through the ring. They operate on a 6-36V power supply and offer NPN output. The sensor features less than 1ms response time, high accuracy and stable performance, which could work well even in the detection of fast-moving small metal objects. It comes with onboard LED for indicating detection status(light up when metal object detected) and sensitivity adjustment knob(clockwise rotation to increase sensitivity). The sensor is sealed in a rugged and anti-rust house that is made of brass nickel-plated flame-retardant material. Moreover, they support a protection degree of IP66 and can withstand a temperature of -25°C ~ 65°C, which are able to meet your requirements both indoor and outdoor regardless of the weather.
