Plug-in terminal blocks
Powerful contact and touch-proof connection – these are the clever features of plug-in terminal blocks.
-
Sensor/actuator terminal blocks
Signal level, potential distribution, and protective conductor function combined in one terminal block – the best solution for control engineering.
-
Test disconnect terminal blocks
Design measuring transducer circuits inexpensively according to your own requirements. Plug-in solutions provide additional technical advantages.
When components are subjected to strong vibrations – in the rail industry, in wind turbine generators or in machine building – this requires maximum contact reliability. The spring-cage connection gives you a constant connection: the spring-cage always exerts the same force on the conductor, regardless of the influence of the user.
Your advantages
- No restriction on cross sections when using conductors with ferrules
- Low logistics costs, thanks to uniform accessories
- Comprehensive range of accessories: standardized for bridging, testing, and marking
- Terminal blocks with spring-cages are a part of the COMPLETE line system
Spring-loaded conductor connection
The spring-cage connection from Phoenix Contact is extremely user friendly, thanks to its front connection:
- Open the terminal point with a standard screwdriver.
- Insert the conductor into the clamping space and remove the screwdriver. The conductor makes contact automatically.
A large connection space in an extremely compact design – these are further advantages of the patented spring-cage technology. They allow you to wire conductors with a nominal cross section either with or without ferrules. You can clamp all types of copper wires up to 35 mm² without pretreatment.
Double function shaft
Connect up to 50 terminal blocks in just one step – with 2- to 50-pos. bridges.
And that's not all: two potentials can be routed in parallel through a terminal point in the double function shaft. Simply disconnect individual contact tabs from the standard bridge, and bridging between non-adjacent terminal blocks is established. The contact points can also be marked.
