Stripe Actuators BIMORPH

Character

Bilaminar, flexing actuators featuring:
large deflections
useful blocking forces
surfaces protected from environmental hazards
electrical leads / no leads
custom dimensions available
competitive pricing


Typical Applications

Use Stripe actuators in applications that demand sensitivity or a large response:
  Braille machines
  needle control in textile weaving
  accelerometers
  opening / closing valves
  small-volume pumping devices
  switching applications - touch switches - making / breaking electrical contact
  cooling devices for electronics (no electromagnetic noise)

Custom Design and Engineering Services
If the dimensions or performance characteristics of standard Stripe actuators do not fit your needs, we can custom-manufacture these actuators to your specifications. Before you request custom products, however, we recommend you evaluate standard Stripe actuators for your application by varying the free length, the method of mounting, and/or the applied voltage.


Deflections and blocking forces measured at maximum driving voltage in direction of polarization..
