PIT – Push-in terminal blocks with plug forces reduced by 50 percent enable the direct tool-free insertion of cables starting at 0.34 mmÂ².
Advantages Unlock new Fields of Application
The advantages of this direct plug technology open up new fields of application for the terminal, such as sensor wiring in mechanical and plant engineering. The advantages also have an effect here. Like the other connection technologies from Phoenix Contact, the PIT also enables a secure, gas-tight and vibration-resistant connection.
The cable is disconnected by pressing the integrated latch. The latch’s surface is designed so that it can be operated with any screwdriver – slot, Phillips or other “pointed” tools of various sizes. Even the pressure of a ballpoint pen is enough to disconnect a cable.
The signal-coloured latch enables clear identification of the PIT terminal point. The service area and wire feeds are clearly separated so that for each terminal point the user only finds a single position for the feeding the wire. Among the numerous connection technologies on the market, PIT rises above the rest because the technology is self explanatory in its application. This prevents wiring errors caused by wrong cable connections.
For Cables between 0.14 and 4 mmÂ²
Fully-isolated operation is an advantage in terms of safety. Working under pressure contravenes both norms and accident prevention regulations, but it still occurs in real life. Measurement, testing and rewiring during ongoing operation can also happen. The PIT latch enables safe contact protection and its isolation material keeps the internal contact elements separate from the service tool. This prevents direct contact between tools and current-carrying parts.
PIT accommodates rigid or finely stranded cables from 0.14 to 4 mmÂ². Finely stranded cables that have not been pre-assembled can be connected through the simple use of the latch. The generously designed cable feed trough prevents the cable from fanning out. An integrated spring stop protects the contact and reliably restricts the spring path.
The PIT’s design is compact and straight, and cables are connected on the front side. A double function shaft in the middle of the terminal enables the cross-connection of potentials with plug-in bridges or for testing purposes.
A System with Uniform Accessories
The PIT terminal blocks form a fundamental component of the "CLIPLINE complete" terminal block system (see sidebar). Like other series, such as screw, spring-cage, quick and bolt connections, PIT uses the same complete line of accessories, such as plug-in bridges, testing equipment and labelling. This significantly reduces the cost of part storage. The compatibility of these systems also extends to other overlapping areas. For example, 10, 16 and 35 mmÂ² feeds can be done with screw or spring-cage connectors, and the distribution of potentials can be performed with push-in technology or a fast connection system.
