	Clutch Engagement
	Your choices are...
	Noncontact		Devices use a noncontact technology such as a magnetic field or eddy currents to provide engagement and drive.
	Friction		Friction between contact surfaces transmits power. This is the most common configuration.
	Magnetic Particle		Magnetic particle products have a layer of fine particles between the stator and rotor. An input current to the stator coil creates a magnetic field that lines-up the particulate to provide load engagement (clutches) or slowing (brakes). The coupling torque is controlled directly by the magnetic field that is created by the input current. Magnetic particle brakes provide good control and a wide range of holding torque at any speed.
	Toothed		Toothed contact surfaces transmit power without slipping. No heat is generated. Devices are engaged only when stopped or running at a slow speed (< 20 rpm).
	Wrap Spring		Torque is transmitted from input to output by a coiled spring that wraps around the output element. The device is disengaged when the spring is uncoiled via a control tang at its end.
	Oil Shear		Drive engagement is achieved by the viscous shear of transmission fluid between the device's plates.
	Plate / Disc		The torque level is controlled by compression springs which force plates together.
	Ball Detent		Ball detent is a slip mechanism in which, upon overload, balls ride up out of seats to overcome springs or air pressure engagement.
	Roller Detent		Rollers, held in place by springs, wedge between the inner and outer races to engage the clutch.
	Pawl Detent		Pawl detent is a slip clutch mechanism in which, upon overload, the pawl overcomes spring or air pressure engagement and rotates out of its detent.
	Sprag		Sprags are steel wedges that tip in one direction to wedge between inner and outer races. They can be configured with either the inner or outer race as the input or output. Too much torque makes the sprags tip so much that contact is not maintained. Often, sprag clutches can transmit more torque than other designs of slip or overrunning clutches.
	Other		Other unlisted, specialized, or proprietary clutch engagement mechanisms.

	Spring Assistance:
	Your choices are...
	Spring Actuation / Engage		The device is spring-actuated and needs power to engage.
	Spring Return / Disengage		The spring provides return force and the device needs power to disengage.

	Magnetic Clutch Type (if applicable):
	Your choices are...
	Permanent Magnet		Permanent magnets can be used in different ways. Some are used to provide engagement or disengagement actuation force. Others provide the magnetic field for hysteresis. Since they do not use electrical power, permanent magnet clutches are often used in situations that require greater levels of safety.
	Electromagnetic		Electromagnetic clutches use a coil which, when energized, creates a magnetic field that pulls the armature toward the rotor. Once in mechanical contact, the rotor turns at the same rate as the armature and affects the drive. When unpowered, the armature retreats back to an air gap from the rotor.
	Hysteresis		Hysteresis uses noncontact magnetic fields to apply resistance or engage load rotation. Torque loading may be applied independently of shaft speed. The magnetic torque is frictionless because the magnetic flux field operates in the air gap between the rotor and the stationary poles. Brakes and clutches that use hysteresis are suitable for precision tensioning and holdback applications where close braking control is important, or when variable clutch engagement of a load is required.
	Eddy Current		Eddy current products use a magnetic field to induce eddy currents in the load. The load engagement, whether actuation (clutch) or slowing (brake), can be precisely controlled by controlling the magnetic field. Because no surfaces come into physical contact, there is no mechanical wear. Most eddy current devices are used in low-power applications.
	Other		Other unlisted, specialized, or proprietary electric clutch operations.

	Zero Backlash		There is no play or backlash during the engagement of the load and no load disengagement during a direction reversal.
	Washdown Capable		The housing is rated for washdown cleaning.
	Bi-directional		Devices can be set-up to rotate in either direction.
	Automatic Re-engagement		The clutch re-engages the load when the torque drops to an acceptable level.
	Slip Indication		Slip indication can move a pin radially when an overload occurs, or send an electrical signal to the drive motor.
