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.

Legal guarantee

Harmonised EU legal guarantee notice

Minimum two-year legal guarantee protection for goods sold in the European Union.

Consumers can claim their rights under the legal guarantee of conformity, for example if goods:

  • do not match the description;
  • do not function as intended.

Sellers are liable for any lack of conformity which existed when the goods were delivered, and which becomes apparent within the legal guarantee period. Sellers in such a situation are required to offer:

  • free repair or free replacement;
  • in some cases, a price reduction or full reimbursement.

Some countries have a longer legal guarantee period. For second-hand goods, a shorter period may apply, but not less than one year.

What to do if you receive non-conforming goods:

  1. Contact the seller as soon as possible to report the issue;
  2. Provide proof of purchase, such as a receipt, invoice, or bank statement.

Sellers and producers may also offer commercial guarantees, which apply independently from the legal guarantee. For example, you may see this GARAN label representing a commercial guarantee of durability offered by the producer at no additional cost and covering the entire good.

For more information on your rights in a specific country, visit the page below or ask the seller. https://europa.eu/youreurope/guarantees
