Products for Inductive Energy and Data Transmission By Larry Robbins, President — Commercial Division, SMW Autoblok Corp.
W
ith contactless inductive coupler systems, SMW now offers the technolo-
gy to transmit energy and data, contact-free, between stationary and moving components via an air gap. SMW’s new full product range includes standard couplers as well as couplers for complex customer-specific designs. Standard couplers are axial
couplers with threaded fasteners commonly used in sensor tech- nology. With their method of fix- ing these are easy to install and are quickly integrated, due to their plug-and-play functionali- ty. The built-in LED display always notifies users of the sys- tem’s status. Radial couplers for rotary applications are available with diameters of up to 11.02 in. (280 mm) and large internal diameters.
Inductive Couplers An inductive coupler system
consists of a stationary coupler and a movable mobile coupler. By using such couplers in a sys- tem, power can be supplied to sensors, actuators, or control

wear- and maintenance-free and replaces traditional
transmission methods using cables, contacts or slip rings.
components and at the same time, any necessary data signals can be transmitted bidirectional- ly in analog or digital form. Transparent coupling of
entire fieldbuses such as CAN or Profibus is also possible. Another feature is the ability to transfer up to 1,500W of power at high band- widths for operating actuators. Inductive transmission technology is completely wear and mainte- nance-free and replaces tradition- al transmission methods using cables, contacts or slip rings. In automation applications
especially, cables and contacts are subject to very high wear and tear and this can, for example, lead to machine downtime due to broken cables. Inductive coupler systems are protected to IP67 and therefore can be used in harsh, demanding environmen- tal conditions; they are also insensitive to vibration. SMW’s newly developed
F280 inductive radial coupler transmits energy and data con- tact-free via an air gap of approx- imately 0.12 in. (3 mm) between its stationary and moving compo- nents. The inductive coupler sys- tem consists of a stationary cou- pler and a movable mobile cou- pler. The stationary coupler can,

for example, be incorporated into the machine or into set up sta- tions and the mobile coupler is incorporated on the pallet side.
Flexibility and Operational Safety
Power of up to 1,500W can
be transmitted between the sta- tionary and mobile couplers. In addition, two CAN bus channels and two digital signals can be
