This is a special 4mm vibration motor designed for low current / low power consumption. This motor is available with or without the PCB mounting bracket and is also available with a silicone rubber sleeve as well. For minimum orders of 1000 pieces we can add a connector on the end of the wires. NOTE: Although we do have samples of this motor in stock, our tooling for the PCB bracket needs to be replaced and there is currently no demand for this bracket to justify making a replacement tool. If you interested in using this configuration in your design please contact us to discuss this issue.    If you need this motor without the PCB bracket order S4Z08B037-452  ( 17mm  leads )
