Weidm ller Presents FreeCon Contactless
Contactless power transmission - maintenance-free
and up to 240 W with high power density, maximum
efficiency. Thanks to FreeCon Contactless from
Weidmüller, customers who employ industrial robots
on their production lines can now avoid contact related
failures and cut maintenance costs considerably.
the line can obtain a far higher degree of efficiency
compared with comparable solutions that are available
on the market.
Burnt, bent or dirty contacts can often be the cause of
time consuming and costly production failures. This is
all the more true of applications that require frequent
plugging cycles. Certain models of industrial robots
performing frequent tool changes are prone to suffering
such system errors like this; the level of wear on moving
parts can be especially high.
In some scenarios industrial robots can perform
several hundred tool changes per day. In this regard,
conventional contacts are subjected to high levels of
wear. With FreeCon Contactless, customers will benefit
from a reliable and maintenance-free connection. The
process of charging driverless transport systems can
now also be automated via FreeCon Contactless. High
maintenance slip ring transmitters can be replaced too,
since it securely transmits power even in the case of
rotational movements.
FreeCon Contactless allows power to be transmitted
via an ‘air gap’ by means of an inductive resonance
coupling. This is a solution that’s completely wear-free
and especially efficient. By doubling the power density,
Unlike conventional plug-in connections, which only
provide IP 20 protection when unplugged and are
therefore unprotected, FreeCon Contactless offers IP
65 - permanently. FreeCon Contactless also enables
reliable and contactless transmission of up to 240 W
of power with compact dimensions and maximum
efficiency. The transmission can even be controlled via
PLC. It is therefore possible to switch 10 A directly via
the PLC without the need for further contactors. FreeCon
Contactless provides complete protection against
humidity and dirt.

One week, £65,000 saving with our Sinergy e-TRacKER
The client – a manufacturer of heating products – installed a Sinergy
e-TRacKER sub-metering unit to get an in-depth view of its energy usage
over one week. When the stats were examined the company discovered
its electricity meters were making incorrect readings. The matter was taken
up with the power supplier and a refund of £65,000 issued along with an
assurance that future bills would be correct.
The e-TRacKER, which took about 30 minutes to install between the Mains
supply cable and the Main Distribution Board, was removed after one week
and the statistics examined. The client, with the aid of the e-TRacKER,
identified that its electricity meters were reading incorrectly. They questioned
the billing data with their supplier and received a refund of £65,000.The
Sinergy e-TRacKER is a portable kWh meter allowing users to monitor
incoming power supply, specific circuits/equipment etc to show the pattern of
demand over an hour, day, week or month. The unit utilises non-invasive clipon transducer (CT) clamps that are quick to install and do not require power
being turned off. They are magnetic-backed so attach easily to switch boards
making them perfect for temporary monitoring.
e-TRacKER measures current from 10Amps to 2500Amps. The system offers
16 days of battery life or run s off mains supply. Other features include pulse
input, optional voltage connections, CT amps range indicator and EV-Trac
electrostatic phase identifier.
