Vishay Intertechnology has announced that it has added five new devices to its line-up of IHPT solenoid-based haptic actuators featuring Immersion Corporation licenses, offering additional sizes and force levels.
Providing 12V operation for LCD displays, touchscreens, touch switches, and button control panels for human-machine interfaces (HMI) in automotive and commercial applications, the actuators deliver high pulse and vibration capability for clear, high-definition (HD) tactile feedback.
Available in four sizes from 29mm x 21mm to 44mm x 37mm — with variable force output up to 120N — the devices feature a compact, two-piece construction with mounting holes for easy installation and direct application of force.
The actuators’ fast response time of 5ms — combined with their high mechanical force — allow them to produce HD haptic effects with operating voltages from 8V to 16V. Vishay says the IHPT actuators are ideal for rugged, noisy environments where audio tones may not be adequate to communicate actuation to the user. The devices feature a robust, rigid copper and iron core construction and high temperature operation to +105°C for high reliability in the most exacting of applications.
The automotive grade, AEC-Q200 qualified IHPT1411AFELR73ABA will be used in automotive dashboards and center consoles, and can provide tactile feedback for electronic shift transmissions, steering wheels, seats, and other in-vehicle controls.
The electromagnetic devices’ low nominal 12V operation eliminates the need for the additional high-voltage circuitry required by other technologies. As a result, the company states that its IHPT series can be implemented at a lower cost than competing technologies — including linear resonant, linear wideband, eccentric rotating mass, and piezo actuators — while reducing component height and delivering higher force density.
The devices come bundled with Immersion licenses, so the design-in process is streamlined and costs are lowered further by eliminating the need to purchase a separate license to implement sophisticated haptic effects.
