At only 7 mm in diameter and 2.1 mm thick, Jinlong Machinery’s C0720B series is currently the smallest coin vibration motor on the market. It is available with either an FPC ( p/n C0720B001F) or wire leads (p/n C0720B015F). Versions with foam pads and without adhesive are also available. It was designed for devices requiring vibration alerts or haptic feedback. Because it produces a relatively low vibrational force of 0.4 G, this motor is best suited for use in light weight devices placed directly against the user’s skin. The motor has an operating voltage range of 2.7 to 3.3 V_DC. At 3 V the motors speed is 10,000 (minimum) RPM with an average current consumption of 48 mA. It utilizes a flexible printed circuit (FPC) which may be hot-bar soldered directly to the PCB. It may be driven by either DC voltage or a PWM signal. A driver IC is not required but may be used to produce various haptic effects. Custom FPC's, foam pads, or PSA are available for mass production orders.

If a higher vibrational force is required, please consider using one of Jinlong’s larger sized coin vibration motors. These motors range from 8 mm to 10 mm in diameter and can generate vibrational forces of up to 1.35 G.
