20' Optical Edge Coil Cord | 2-Wire Connection | Commercial Door Safety Edge Replacement | LiftMaster OES

Keep your commercial overhead door's monitored safety system operating properly with the LiftMaster OES-COIL 2-Wire Coil Cord, designed specifically for compatible LiftMaster Optical Edge Systems.

The flexible coiled cord provides the electrical connection between the optical edge junction box and the commercial door operator or switch, allowing the cord to extend and retract as the door travels.

Its coiled design helps reduce loose hanging wire, strain, and premature cable damage caused by repeated door movement, making it an ideal replacement for worn, stretched, broken, or intermittent optical-edge cords.

Optical Edge System Application

The LiftMaster Optical Edge System is a monitored entrapment-protection system designed for compatible commercial door operators.

The OES-COIL serves as the flexible wiring connection between the moving door-mounted optical edge components and the stationary operator wiring.

As the door opens and closes, the coiled cable expands and contracts to accommodate door travel while maintaining the electrical connection.

Why Replace a Damaged Coil Cord?

A damaged or failing coil cord can interfere with communication between the monitored sensing edge and commercial door operator.

Replacement may be necessary when the existing cord shows:

• Broken conductors

• Frayed insulation

• Excessive stretching

• Cuts or abrasion

• Intermittent safety-edge faults

• Damaged coil sections

• Unreliable edge communication

Replacing a damaged cord helps restore a dependable connection between the optical edge and operator.

Common Applications

Ideal for:

• Commercial sectional doors

• Rolling steel doors

• Warehouse doors

• Loading dock doors

• Distribution centers

• Manufacturing facilities

• Service garages

• Industrial facilities

• Commercial overhead doors

• Door operator repair and maintenance

Installation Note

Connect the OES-COIL according to the wiring instructions for the specific LiftMaster commercial operator and Optical Edge System.

After installation, the monitored edge and door operator should be tested to confirm proper entrapment-protection operation before the door is returned to service.
