## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0447:1` (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/SEN0447:1.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

Unlike the inductive proximity switch that can only detect metals, the capacitive proximity sensors can be used to detect all non-metallic objects with static electricity besides metal objects.

With a power supply range of 10~30V, this capacitive proximity sensor features an adjustable detection range from 1~10mm and an indicator for feeding back device status in real-time. Fully enclosed by a PBT plastic shell, the sensor meets IP67 waterproof and dustproof rating, which can be applied to both outdoor and indoor projects. In addition, it has small temperature drift and high detection accuracy and can be used in scenes such as mechanical automation, security equipment, and object detection.

The standard detection object of the switch factory is 20\*20\*1mm pure iron block. The detection distance is greatly affected by the size, thickness, and conductivity of the detected object. The larger and thicker the detected object, the better the conductivity, the longer the product detection distance, and vice versa.
