| Actuator Configuration: | |||
| Your choices are... | |||
| Stack | Piezoelectric stack actuators are manufactured by stacking up piezoelectric disks or plates. These disks are electrically connected. The stack axis is the axis of the linear motion. When a voltage is applied, the thickness of the layers increases and thereby the total stack lengthens. | ||
| Tube | Piezoelectric tube actuators are monolithic devices that contract laterally and longitudinally when a voltage is applied between the inner and outer electrodes. With quadrature electrodes the tubes can be operated as XY scanners. | ||
| Disk | A disk actuator is a device in the shape of a planar disk. | ||
| Ring | Ring actuators are disk actuators with a center bore. This makes the actuator axis accessible for optical, mechanical, or electrical purposes. | ||
| Other | Other unlisted, specialized or proprietary configurations, such as block, disk, bender, bimorph, etc. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| |||
| Ultrasonic Operation? | Ultrasonic actuators are specifically designed to produce strokes of several micrometers at ultrasonic (>20kHz) frequencies. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
| |||
| Electrical Connectors | |||
| Your choices are... | |||
| DB-9 | Similar in appearance to a CAPITOL D, D-subminiature connectors are generally referred to by the number of pins or sockets they have. For example DB-9, DB-25, etc. The design of these connectors varies little between manufacturers, except for the color of the shell. | ||
| BNC | The BNC is essentially a miniature version of the C connector that is a Bayonet version of the N connector. BNC connectors are available in both 50 and 75 ohm versions; both versions will mate together. The 50 ohm designs operate up to a frequency of 4 GHz. BNC connectors are used in many applications, some of which are flexible networks, instrumentation, and computer peripheral interconnections. | ||
| Two wires AWG26 | Two 15.9-mils diameter (AWG26) wires. | ||
| Two wires AWG30 | Two 10.0-mils diameter (AWG30) wires. | ||
| LEMO™ Connector | LEMO® is a precision push-pull locking connector for demanding applications. LEMO is a registered trademark of LEMO. | ||
| Other | Other unlisted, specialized, or proprietary connector types. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||

|
| ||
| Maximum Displacement: | The maximum elongation (normally specified in μm) that the actuator will produce when the maximum operating voltage is applied. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Blocked Force: | Blocked force is the maximum force (normally specified in Newton, N) that the actuator will produce when the maximum operating voltage is applied. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Maximum Operating Voltage: | The maximum voltage that can be applied to the actuator without impairing its functionality. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Stiffness: | Stiffness is a term used to describe the force needed to achieve a certain deformation or deflection of a structure. For piezoelectric actuators it is the force needed to elongate the device by certain amount. It is normally specified in terms of Newton per μm, or N/μm. | ||
| Search Logic: | All matching products will have a value greater than or equal to the specified value. | ||
| |||
| Resonance Frequency: | Resonance is the frequency at which the actuator responds with maximum output amplitude. | ||
| Search Logic: | User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria. | ||
| |||
| Capacitance: | The capacitance that the actuator exhibits. The capacitance is a function of the excitation voltage frequency. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||

| Length: | The length of the actuator. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
| |||
| Diameter or Height: | The inner diameter in ring or tube actuator and the outer diameter for disk actuators. The height in other configurations. | ||
| Search Logic: | All matching products will have a value less than or equal to the specified value. | ||
