Distributor Johnson Matthey

Signal is proud to distribute the piezoelectric actuators manufactured by Johnson Matthey Piezo Products GmbH, for electronic needle selection on circular knitting machines.

Johnson Matthey Piezo Products GmbH, located in Germany, has spent over 50 years developing and producing piezoelectric ceramics, piezo components and piezo modules in accordance with individual requirements specified by customers world-wide.

These products have been in use for many years and are available in two product lines:

Available in two models and compliant with the most diffused textile fieldbus standard: Siemens© and WAC© Bus (RECAM type).

Applied on many types of circular knitting machines, these actuators are suitable for electronic needle selection systems with a high number of working feeds (large diameter machines) as well as for medium size and sock machines.

Product features

  • 3-wires technology prevents depolarization over time.
  • Fast and repeatable response time; typical flaps switching time is 2,5 ms, complete process is 4,4ms.
  • A wide range of flap profiles are available on catalogue; specific flap profiles can be machined on customer drawings, using high-tensile steel.
  • Field replaceable parts (ceramics, flaps, electronic if any) for all actuator models.
  • One row flaps or two row flaps for 3-way knit technique selection.
  • Flap pitch: fine 3.2, standard 4 mm and 5 mm (special).
  • All metal housing.

All products use piezo ceramic technology that minimizes size and allows for fast working speeds with minimum consumption of energy and no heating.

Johnson Matthey manufactures piezo ceramics internally using proprietary technology, developing top of the range products that have minimal footprint and low power consumption,
