YOUR ADVANTAGES AT A GLANCE

SAVE TIME AND COSTS

Reduce installation and assembly time, and therefore also installation costs, by coupling and uncoupling quickly with the Plug&Play principle. Be faster than any screw or bayonet connection.

DURABLE AND REUSABLE

Create a long-term connection. Our connectors are intended to be used again and again, thanks to their robust design and our extremely high demands on the quality of the materials we choose.

FLEXIBLE AND EFFICIENT

Simplify modifications and maintenance with easy disassembly and pre-wired connectors – even during operation. Plug&Play means quick and safe coupling and uncoupling with little downtime.

COLOR CODING FOR ADDITIONAL PROTECTION

With mechanical coding and over 20 color options, RST® connectors make installation intuitive and error-free, even for less experienced users. Faulty wiring and troubleshooting are eliminated, whether for low-voltage, emergency power, or main power systems. Say goodbye to cable screw connections – the Plug&Play principle revolutionizes your electrical connections!

All variants and options can be found in our shop.

 This way: it's worth it.

IP-PROTECTION – ROBUST, STABLE AND RESISTANT

What you can expect 
from the RST® connector series 

Depending on the respective IP rating of the different RST® models, these round connectors excel in the following areas: 

  • Comprehensive protection against jets of water, including high-pressure and steam jets
  • Temporary and prolonged immersion
  • Complete protection against contact
  • Protection against foreign objects, such as dust deposits and dust ingress
  • High reliability to ensure a stable and continuous electronic connection
Detailed information on IP classes 65 to 69
IP 65        protected against contact, dust and splash water 
IP 66protected against contact, dust and splash water, strong jets of water
IP 67protected against contact, dust and splash water, strong jets of water, temporary submersion up to 30 minutes at a depth of 1 m
IP 68protected against contact, dust and splash water, strong jets of water, prolonged/permanent immersion in water upto 2 hours in 3 m depth
IP 69protected against contact, dust and splash water, strong jets of water, prolonged/permanent immersion as well as strong jets of water such as high-pressure and steam jets

HIGH STANDARDS YOU CAN TRUST

Our connectors are built to meet the highest standards of quality and durability. With decades of expertise, we continually refine and rigorously test our products in-house. For example, our IP68 connectors undergo two hours of testing at a depth of three meters and are subjected to high-pressure splash water tests. Additionally, mechanical stress tests, like IK impact resistance, ensure robust performance. This meticulous process guarantees reliability in every application.

INTERNAL WATERSTOP FOR EXTRA PROTECTION

Protect your devices from moisture and water infiltration with our advanced contact sealing technology. Temperature fluctuations, condensation, or faulty installations can lead to water ingress via the capillary effect. That’s why each contact in our connectors features its own seal, providing longitudinal watertightness and ensuring long-lasting safety for your cable installations.
