Inertia Dynamics offers a full line of wrap spring clutches and brakes. Both electrically- and mechanically-actuated units are available in four standard models as well as custom designs for all your applications.
	Model ISC Clutches ISC shaft-mounted clutches feature high torque-to-size ratios and create positive engagement. They provide consistency, repeatability and long life. Engagement and disengagement are virtually instantaneous.
	SC Series Clutches Model SC clutches are mechanically-actuated. They can be used in overrunning, start/stop, and single revolution applications.
	DCB Series Clutches The DCB clutch/brake is designed to start and stop a load. It will stop the load in the same position without any cumulative error. The DCB will stop any load that is able to start. The control tangs are used to hold open the clutch or brake spring, which are wrapped in opposite directions. When the clutch and brake control tangs rotate with the input hub, the input hub and output shaft are engaged by the clutch spring. When the stop collar locks the control tang of the brake spring, it wraps down engaging the output shaft to the brake hub. The clutch spring unwraps at the same time, allowing the input hub to freely rotate.
