Automotive Grade Haptic Feedback Actuator offers High Force Density and HD Capability for Touch-Based Interaction

Vishay Intertechnology has introduced a new customizable haptic feedback actuator IHPT-1411AF-ABA that features a compact, two-piece construction with mounting holes for easy installation and direct application of force. It is an electromagnetic device that converts electrical energy into a mechanical pulse or vibration for touch-based interaction that can be controlled by varying the input voltage amplitude and duty cycle. This device will be used in automotive dashboards, center consoles, and touch screens for human-machine interfaces and can provide tactile feedback electronic shift transmissions, steering wheels, seats, and other in-vehicle controls.

This device features a fast response time of < 5 ms that can be utilized to produce multiple high definition (HD) haptic effects with operating voltages up to 16V. With an operating temperature range to +105˚C, this device’s low 12V operation eliminates the need for the additional high voltage supplies required by other technologies and can drive a 0.5 kg load to 6 g of acceleration with a 12 V, 5 ms pulse. Moreover, its simple bobbin and core components allow designers to layout a return spring configuration that can be incorporated into the display mounting, eliminating the need for additional housing.

Features

• Solenoid construction provides high impulse vibration for clear tactile feedback in noisy environments

• This IHPT device can drive up to a 0.5 kg load to 6 g’s of acceleration with a 12 V, 5 ms pulse using Vishay’s spring return test fixture

• Standard lead termination is dipped 100 % tin solder; customer-specific connectors available upon request

• Compact, two-piece construction with mounting holes; stationary “U” core and moving “I-bar” for easyL implementation in touch screen or touch button application

• AEC-Q200 qualified

Applications

• Automotive dashboards, touch screens, and center consoles

• Physical feedback for electronic shift transmissions, steering wheels, seats, control panels

• Touch screens for human-machine interfaces

Availability

Samples and production quantities of the new haptic feedback actuator are now available with lead times of 12 weeks.
