Exploring Haptic Actuators: Diverse Sizes and Force Levels

The latest haptic actuators are revolutionizing the way we interact with technology, delivering high pulse and vibration capability to provide clear, high definition tactile feedback. These actuators are designed for a variety of applications, including LC displays, touchscreens, touch switches, and button control panels for human-machine interfaces (HMI) in automotive and commercial settings.

Available in four different sizes ranging from 29 by 21 mm to 44 by 37 mm, these cutting-edge devices offer variable force output of up to 120 N. Their compact, two-piece construction with mounting holes allows for easy installation and direct application of force. With a fast response time of just 5 ms and the ability to operate at voltages from 8 V to 16 V, these actuators can produce high definition haptic effects that are perfect for noisy environments where audio cues may not be sufficient.

The automotive grade IHPT1411AFELR73ABA is AEC-Q200 qualified and ideal for use in automotive dashboards and center consoles, providing tactile feedback for electronic shift transmissions, steering wheels, seats, and other in-vehicle controls. Other models like the IHPT1207AGELR39AB0, IHPT1710ACEL1R2AB0, IHPT1411AFELR73AB0, and IHPT1614ACEL2R7BB0 find applications in factory automation, consumer appliances, medical devices, and more. However, due to licensing restrictions, these actuators are not available for gaming applications.

One of the key advantages of the IHPT series is its low nominal 12 V operation, eliminating the need for additional high voltage circuitry required by other technologies. This not only reduces costs but also results in a more compact design with higher force density. The actuators come bundled with Immersion licenses, streamlining the design-in process and further lowering costs by eliminating the need for a separate license to implement sophisticated haptic effects.

These haptic actuators can drive a 0.5 kg load to 6 g of acceleration with a 12-V, 5 ms pulse. With features like RoHS compliance, halogen-free materials, and Vishay Green certification, they offer high reliability and environmental friendliness. Vishay also provides customization options for the actuators, allowing for tailoring to specific design requirements in terms of size, shape, core material, windings, terminations, and performance.
