## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=SEN0347:1` (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/SEN0347:1.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 is a pair of photoelectric switches with a detection distance of up to 1.5m and a fast and stable response time of less than 1ms. The module consists of a transmitter and a receiver. The transmitter contains an infrared diode that can emit infrared rays with strong penetration, thereby ensuring that the sensor can achieve stable signal reception regardless of weather, which greatly improves its measurement accuracy.

The module has a small size of 22.4\*11.2\*8.3mm and can be easily installed in a narrow space; It can work well within a temperature range of -20°C ~ 65°C, which can be used in both indoor and outdoor environments.

This switch uses a DC voltage of 9-24V, which can be widely used in machinery automation, automobile anti-theft and other industries for detection, counting, gate passing, or other industrial automation sensing conditions, and can also be used in intelligent robot competition for speed detection and timing, etc.
