Pluggable Electrical Installations For Power & Signals

Pluggable Electrical Installations For Power & Signals

RST®20i6 (6-pin) and RST®20i7 (7-pin) connectors

As industry and building technologies continue to evolve through diverse applications, there are increasingly greater demands for fast and safe electrical installations for high-load applications. Wieland Electric is responsive to this demand by expanding our RST® CLASSIC portfolio to meet these needs. The new RST®20i6 (6-pin) and RST®20i7 (7-pin) connectors extend the versatility of electrical installations through increased functions. In addition, the connectors have an elevated Type 6P protection rating for outdoor use. An optional, integrated barrier seal prevents moisture from spreading along the cable system.

A comprehensive design philosophy, down to the last detail

Available in both screw and crimp connection technologies, the RST®20i6 and RST®20i7 connectors are capable of managing loads of up to 20A* and support conductors up to 2.5 mm². The RST®20i6 (6-pin) connector was developed specifically for dimmable emergency light applications, a key element in industrial safety. The RST®20i7 (7-pin) connector was developed as an ideal solution for combining polyphase systems with signals. Three codings ensure both mechanical and color-based differentiation between circuits, with an added safety feature that distinguishes between grounded and ungrounded wires. Mains and extra-low voltages (SELV) can be connected via internal insulation coordination inside a connector housing, with compact connectors allowing for high modularity and adaptability for dynamic application requirements. These models are provided in both straight or angular versions, as well as additional options compatible with all common cable diameters, including connectors with two cable inputs for through-wiring applications.

High Current, High Voltage Power Bus for Manufacturing, Conveying & Logistics

Podis PowerThe podis® power bus system provides decentralized and flexible power distribution for factories, airports and warehouses. With its unique design and connection technology, the podis® system is easy, fast, & safe to install and maintain. The new 5-core tray cable system provides higher load capacity to allow for more drives per segment and longer cable sections. Compared to other installations that require long cable lengths, the voltage drop along the bus is significantly reduced. The podis® power bus system is ideal for conveyors at airports, warehouses, distribution centres, and production plants.


  • Copper displacement connection technology
  • 6 mm2 (10 AWG) cable size
  • 5 core tray cable with all cores in one plane
  • Current load 32A
  • Voltage 600V CSA/UL

The podis® 5g6 connection system reduces installation labor by 70% or more by reducing the need for traditional point-to-point pipe and wire.  Waste is significantly reduced, and connection modules can be moved and reused as the cores of the bus cable remain intact and undamaged.  System changes are easily achieved as modules can be moved to different locations on the cable without the need to replace entire cable sections or loss of conductivity.
