Press Release Summary:
Model EC20CB incorporates friction clutch within same package to stop loads when drive is disengaged. Suited toward applications where run-on is problematic, EC20CB measures 45 x 36 mm. Designed for 24 V systems, device utilizes friction disc brake to bring driven axes to standstill. Clutch has ~2.2 Nm rated torque, with braking torque of ~0.2 Nm.

New Wrap Spring Clutch has Braking Features
For fast stopping and holding of low friction loads
Santa Fe Springs, August 19, 2002: Well known for their high torque density and cost effective transmission devices, wrap spring clutches have taken on a new dimension with the introduction of the EC20CB from Densitron.
By incorporating a small friction clutch within the same package to stop the load when the drive is disengaged, the EC20CB is an absolute 'must' in applications where 'run-on' is a problem, such as in paper transport systems where the roller inertia causes rollers to run on when drive is disengaged.
Measuring approximately 45 x 36mm, the EC20CB has a very high torque density compared to motors of similar torque, and can fit into space constrained applications where a motor would take up too much volume.
Designed for 24V systems, the device comes into operation as the drive voltage to the clutch reduces. The clutch will disengage and then as the voltage drops further, the friction disc brake will engage to bring the driven axis to a standstill.
The clutch characteristic is similar to Densitron's standard EC20 clutch with approximately 2.2Nm rated torque. Braking torque is around 0.2Nm to bring the load to a standstill. When energized, the brake disengages and the clutch engages. When de-energized, the friction brake is applied to bring the load to a stop quickly and/or hold the load in position while the clutch is disengaged.
OEM prices start at under $28 each for 1,000 pieces. Delivery is from stock to 12 weeks ARO depending on availability.
