Safe and reliable connections are essential in many industrial sectors. The PUSH IN technology saves a lot of time and guarantees maximum contact reliability, plus, it is particularly convenient to use: You take a stripped solid or fine-stranded conductor with a crimped-on ferrule, insert it into the clamping point up to the stop, and the safe and gas-tight connection is complete. Very simple and without any tools.
Compared to tension clamp connections, PUSH IN saves up to 50% of the wiring time because you simply insert the conductor into the terminal point to make a connection.
Wiring is exclusively and easily accessible from the front. You don’t need a tool to open the clamping point, so both your hands remain free. For loosening, you use a normal screwdriver.
Once wired, the spring ensures constant contact force over decades. The PUSH IN connection is easy to handle, even for automatic wiring machines, and is therefore ideally equipped for the future.
With PUSH IN connection solutions, you no longer need a screwdriver to opened the terminal points. Instead, you simply plug the conductor into the terminal point. This saves time. PUSH IN connections are particularly suitable for solid conductors, for stranded conductors, and for fine-stranded conductors with crimped-on ferrules. Furthermore, ultrasonically welded conductors can also be connected. The times shown refer to the conductor connection operation. All connection types can be used with or without ferrules.
In principle you can distinguish between two types of connection: Spring connection technology and screw connection technology. Both can be divided into several sub-categories and have specific characteristics:
Spring connections, which include the PUSH IN and the tension clamp connection, enable a maintenance-free and gas-tight connection as well as a permanently shake-proof and vibration-resistant connection.
Screw connections, which include the clamping yoke and bolt connections, are particularly suitable for connections with large conductor cross-sections. Weidmuller is one of the few well-known manufacturers that has all the standard connection types in their portfolio. All connection technologies are available from a single source.
PUSH IN connections provide safety in almost every application. Due to the fact that most of them have been tested beyond the standard norm, they can also be used in sensitive areas and harsh environments. These include traffic engineering, process engineering, energy supply, or ship building. Every day, PUSH IN technology faces many challenges in machines and systems around the globe. In short: with PUSH IN, you as a user are always on the safe side!
The PUSH IN connection technology separates the mechanical from the electrical function. As a result, it operates according to the same basic principle as the proven clamping yoke and tension clamp connection technologies. High-quality materials ensure consistent contact quality.
Rectangular crimped ferrules can be inserted very conveniently into a PUSH IN connection. Trapezoidal crimping forms according to EN 60947-1 are particularly suitable for compact device connections.
The optimal combination of crimp density and volume, the WM crimp delivers the best pull out forces from the terminal while simultaneously ensuring a gas tight crimp.
The square form matches the shape of the clamp in the terminal, with the correct orientation this ensures an even better hold of the ferrule.
Universal crimp die ensures failure free processing in the workshop.
Symmetrical Crimp form allows insertion in any orientation, perfectly suited for automated wiring of the cabinet.
In order to optimally exploit all the advantages of the PUSH IN connection technology, we offer the best basis. In accordance with the motto “consistent from the field to the control system” Weidmuller provides a complete PUSH IN product range covering control systems, relay modules, terminal blocks, surge protection, and sensor/actuator cabling in the field. The standardized operation makes it as easy as possible for switch cabinet builders to work productively.
Even the component design benefits from PUSH IN
The consistent component design provides the user with a clearly arranged system that is particularly easy to maintain. Due to the integrated test taps, you can carry out all maintenance and test tasks as well as troubleshooting much more easily, safely, and quickly.
The wiring for PUSH IN solutions is exclusively from the front. This is a clear advantage in relation to screw connections, where the conductor entry and actuating element are at a 90° angle – with side openings that are often difficult to access.
A normal screwdriver is sufficient to release the conductor. Operation and conductor entry are optically and physically separated from each other. The pusher provides additional protection against accidental contact.
The integrated test tap is suitable for all common measuring tips (DigiCheck, Duspol, multimeter). In contrast to measuring on a screw or tension spring, the user can operate the measuring device with both hands free.
In all PUSH IN products, accessories such as cross-connection channels, separator areas, holders for strip markers, etc. are consistently designed. This allows uniform, fast, and error-free installation.
The modern and uniform design of the PUSH IN products already offers many advantages in wiring and testing. But tool-less connection and a consistent design are also important for the automated assembly and wiring processes of the future. These factors are already taken into account in our PUSH IN products. For example, the housing contour of our A-Series modular terminal blocks is already designed for automatic mounting rail assembly. The straight edges provide a secure hold for the gripper of a robot arm. PUSH IN connections are therefore easier to handle than other connection methods, even for automatic wiring machines.
Conformity to standards and consistently high quality of all electronic components are among the factors that are decisive for success in product development. We have an accredited test laboratory and the corresponding approval certificates, with which we prove the high quality level of Weidmuller’s PUSH IN connection technology. We go beyond the prescribed framework of type tests and carry out the following tests, among others, to ensure the safety of our connection solutions.
