Technology	Electromechanical wrap spring clutch
Low Wattage	The EC25LL requires only 2.5 watts of power for engagement
High Torque, Small Package Size	The EC25LL provides 2.83 N-m (25 lb-in) of total load over a life of 1 million actuations with an outside diameter of about 30 mm (1.2 inches), and a shaft length of about 30 mm (1.2 inches). Part weight is 83 g (0.184 lbs). It also provides approximately 60 million bearing revolutions for typical applications. 2 - 10 times the bearing life of a standard EC25.
Rapid Acceleration	After spring wrap-down, the EC25LL will accelerate loads from zero to full speed in less than 3 milliseconds.
Consistent Performance	Engagement is made with virtually no slippage and disengagement is almost instantaneous.
Power Source	All Reell clutches operate on either filtered or unfiltered dc power. The use of filtered power is recommended for better life at high speed.
Operating Parameters	EC25LL performance is best within the following conditions: 0°- 40° C (32°-104° F) 100-800 rpm typical, 1400 rpm max. Minimum load friction torque 0.05 N-m (6.0 oz-in) plus customer input bearing torque.

Single Direction	Wrap spring clutches provide torque only in the direction in which they wrap down. This allows for overrunning.
Relative High Shock	Due to the EC25LL's rapid acceleration, system inertia effects can be significant. In some applications an in-line slip device may be used for shock absorption. Please contact a Reell Sales Representative for more information regarding this option.
Engagement Relative to Speed	The EC25LL relies on relative motion between the input and output for engagement. Thus, the slower the speed, the longer the time until engagement.
