Rainswitch 1000 R GI: Easy rain detection via digital input

News of 09 April 2026

Reliable rain detection for a wide range of systems

In many applications, rain is required as a switching signal. The new Rainswitch 1000 R GI rain sensor provides a simple and versatile solution for this purpose. The sensor reliably detects precipitation and reports the status via a potential-free contact.

Integration is straightforward via a digital input, while the connected system handles further processing. This allows the rain sensor to be flexibly integrated into a wide range of applications – from smart home solutions and roof window controls to PLC or smoke and heat exhaust systems, as well as an addition to KNX projects.

Presented at Light + Building 2026, Rainswitch 1000 R GI is now available in the Elsner Online Shop.
