Amphenol GEC PowerLokTM power connectors have been added to TME’s product line.
This is a brand-new product from a well-known source that is mainly intended for manufacturers and electrical engineers working in the hybrid and electric vehicle sectors. Furthermore, the items displayed are appropriate for installations of renewable energy, particularly energy storage devices.
Although all introduced products belong to the same family, this offering should be divided into two groups:
PowerLok™ G2 plugs and sockets, and PowerLok™ 4.0 G2 connectors.
PowerLok G2
These products, illustrated in the photos in the table above (plugs), are high-performance electrical
connectors made using aluminum alloy. They can conduct currents up to 300A at a nominal voltage of 1kV
DC. They offer a wide range of configurations, including straight and angled versions. The assortment
includes both wire-mounted plugs (cross-sections up to 150mm2) and panel-mounted plugs. A single
connector can have 1, 2, or 3 pins. At the same time, the body design ensures complete insulation and
shielding of contacts to protect operators and minimize interference.
The main applications of these products are power trains in hybrid and fully electrified vehicles: in
passenger cars, trucks, buses, as well as agricultural machinery and off-road vehicles. Given such
demanding applications, the products are made to a protection class reaching IP67, i.e., high water
resistance and full dust tightness that could impair the conductivity of connections. Complete water
resistance is achieved when the connectors are mated.
PowerLok 4.0 G2
Unlike the connectors described above, the PowerLok™ 4.0 G2 sub-series is intended for powering
accessories and components in vehicles (sensors, actuators, servomechanisms, etc.). Their electrical
parameters are therefore slightly lower (currents 5…60A, wires up to 10mm2), but their bodies are also
smaller in size. Here too, high protection class reaching IP69 after connection is ensured. It is worth noting
that all PowerLok™ connectors also feature wide thermal tolerance and can operate in temperatures
ranging from -40°C to 125°C.
Self-locking PowerLok™ 4.0 G2 connectors have a more compact design.
