VISHAY INTERTECHNOLOGY Custom Magnetics IHPT-1411AF-AB0  customizable haptic feedback actuator is suitable for touchscreens, joysticks and touch switch panels in commercial applications. Offering a compact, two-piece construction with mounting holes for easy installation and direct application of force, device delivers high impulse pulse and vibration capability for clear tactile feedback in noisy environments or anywhere a mechanical response to action is desired. With an operating temperature range to +105 °C, this haptic feedback actuator is ideal for rugged environments. The electromagnetic device converts electrical energy into a mechanical pulse or vibration for touch-based interaction that can be varied by power amplitude and duty cycle of the input voltage. The haptic coil assembly, when energized by a DC voltage pulse, creates a magnetic field that attracts the mounted dynamic core piece. When deenergized, the core piece is returned back to its original position by the customer-supplied spring assembly.
