Weidmüller RockStar®: SNAP IN Connector Revolutionises Wiring Of Heavy-duty Connectors

With SNAP IN, Weidmüller has revolutionised connection systems, bringing them to a new level. Flexible, stranded wires without crimped-on wire-end ferrules can be easily inserted into the open connection point and then "click" – that's all it takes to create a secure connection.
No tools are required. And the resulting connection can withstand harsh environmental conditions including heavy shaking and vibrations.
Innovative SNAP IN connection technology has been used for the first time in the RockStar® series of fixed-pole inserts and modules. Fixed-pole inserts with 6,10,16 and 24 poles are available (size 3, 4, 6 and 8) with a rated voltage of 500 V / 16 A. The new HDC inserts allow for quicker, easier, more reliable and more flexible wiring. Maintenance work is significantly quicker. The modular plug-in connector system RockStar® ModuPlug provides even more flexibility. With its range of different modules, it provides the user with multiple options for combining functions individually within an interface. The new SNAP IN connection technology not only serves to save valuable installation space, but the user also benefits from the enormous time savings during installation.
The RockStar® heavy-duty connector series are permanent fixtures within machinery and plant engineering, as well as in the railway and wind power industries. They also support the trend towards modularisation. Cross-model and cross-application inserts are available with various connection systems for screw, tension clamp, PUSH IN, crimp or axial screw connection.
Now, there are inserts that are equipped with the innovative, future-proof SNAP IN connection. Users can easily insert the stripped, flexible, stranded wire into the connection point for the first time, with no need to crimp on a wire-end ferrule. The open SNAP IN system is designed to close automatically as soon as the stripped wire has reached the correct position and the spring has triggered.
The operating principle is comparable to that of a mousetrap. The contact closes with a noticeable "click", holds the wire in place. The SNAP IN connector is easy to operate and guarantees a reliable and vibration-proof connection. Flexible, stranded wires of 1 to 2.5 mm2 can be connected quickly and reliably without crimped-on wire-end ferrules. And of course, it is still possible to use stranded conductors with wire-end ferrules and plastic collars with cross-sections ranging from 0.5 mm2 to 2.5 mm2 (AWG 20 to 16) with the SNAP IN connection system. The connected wires are released by activating the pusher using a standard screwdriver.
Every contact point for the HDC SNAP IN inserts and modules is also provided with a "measuring point", meaning that testing procedures can be carried out with a standard 2.0-mm test plug.
The fixed-pole HDC-HE SNAP IN inserts are available with 6, 10, 16 and 24 poles (size 3, 4, 6 and 8). The rated voltage is 500 V in accordance with DIN EN 61984, and 600 V AC/DC in accordance with UL/CSA. The rated current (DIN EN 61984) is 16 Amps. As stated before, the SNAP IN connection system provides a high level of reliability even under the harshest environmental conditions.
The plastic housing of the HDC-HE SNAP IN inserts consists of the PC glass-fibre reinforced insulating material PA 66/6. The plastic is UL-listed and approved for railway use. The flammability rating in accordance with UL 94 is V-0. The inserts can be easily inserted at temperatures ranging from -40°C to 125°C. They are plug-compatible with existing HDC-HE inserts with crimp, screw, tension clamp and PUSH IN connection systems.
In addition to the new 5-pole RockStar® ModuPlug modules of size 1 with a rated voltage of 400 V (DIN EN 61984) or 600 V (UL/CSA), Weidmüller also offers a completely new module design for pluggable solutions in the IP20 environment. Especially for distribution solutions on the otherwise unused inside of the control cabinet, these new, one- and three-level ModuPlug modules with SNAP IN connection and rated voltage of 250 V (DIN EN 61984) or 600 V (UL/CSA) open up unimagined possibilities for using space, for example in low-voltage switchgear.
