Frequently Asked Questions

What is the Autonics EC-4 encoder coupling used for?

The Autonics EC-4 plastic encoder coupling connects an encoder shaft to a motor or machine shaft, compensating for minor misalignment while transmitting rotary motion. It is commonly used in industrial automation, packaging, and material handling systems where precise position feedback is required.

What are the specifications of the Autonics EC-4 encoder coupling?

The Autonics EC-4 encoder coupling has a 21 mm outside diameter and is made of plastic. Its manufacturer part number is EC-4. This coupling is designed for light-duty encoder applications where electrical isolation and vibration damping are needed.

Where to buy the Autonics EC-4 encoder coupling worldwide?

3G Electric supplies the Autonics EC-4 encoder coupling to customers worldwide. As a global industrial sourcing partner, we handle full logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this part.

How to select the right Autonics encoder coupling for my application?

To select the correct Autonics encoder coupling, match the shaft diameters of your encoder and driven equipment, and verify the coupling’s outside diameter (21 mm for EC-4) and torque rating. Plastic couplings like the EC-4 suit low-torque, high-speed applications requiring electrical isolation.
