The Miller Edge C182-12B Coil Cord - 18 Gauge - 2 Conductor - 12 ft. Expanded is a Miller Edge coil cord used to carry low-voltage sensing edge or control wiring across a moving door or gate point. This is not an operator logic board or a safety device by itself. It is the connection method between the moving edge assembly and the fixed control side of the system. Correct selection matters because a cord with the wrong conductor count, expanded length, jacket style, or monitoring configuration can create nuisance stops, open edge circuits, failed safety checks, or unsafe loose wiring during travel.
This item is compatible by wiring requirement, edge configuration, and installation layout rather than by one operator brand alone. It may be used with the following applications when the original system documentation supports the same conductor count, length, and connection style:
| Manufacturer | Miller Edge |
| Product Type | Coil Cord |
| Part Number | C182-12B |
| Wire Gauge | 18 AWG |
| Conductors | 2-conductor |
| Expanded Length / Cable Travel | 12 ft. expanded |
| Application | flexible connection between a Miller Edge sensing edge and a commercial door or gate operator control circuit |
| Mounting / Use Style | Moving door or gate edge to fixed operator/control wiring |
| Jacket / Enclosure | Polyurethane jacket |
| Compatible Operator Type | Commercial motorized doors and automated vehicular gates using compatible Miller Edge sensing edge circuits |
| Monitoring / Circuit Note | May be used on compatible 2-wire non-monitored or monitored edge circuits when the wiring diagram supports a 2-conductor cord. |
| Included Components | Coil cord only |
| Notes | Match conductor count, length, termination style, edge configuration, and operator/interface wiring diagram before replacing. |
These numbers are included to help identify the correct Miller Edge cord or related service part. Related numbers are not always direct replacements.
Use this part only where the system calls for a 2-conductor cord. A 2-wire edge may be non-monitored or monitored by a resistor or diode-capacitor configuration, but the cord alone does not define the monitoring method. The edge, plug, controller, and operator wiring determine the correct setup.
Sensing edge wiring is part of the safety system. Do not bypass edge inputs, monitored safety devices, or photo eyes to make an operator run. If the door or gate moves unexpectedly, reverses incorrectly, shows an edge fault, or has damaged wiring, have the system inspected by a qualified gate or commercial door technician.
The Miller Edge C182-12B is a 18 AWG, 2-conductor coil cord used as a flexible moving connection between a compatible sensing edge and a fixed operator, controller, interface module, or junction box.
No. It is for applications that require a 2-conductor cord with 12 ft. expanded. The edge configuration, monitoring method, operator input, and jacket requirement must match the original installation.
It may be used on select 2-wire monitored edge circuits such as resistor or diode-capacitor configurations when the Miller Edge/operator wiring diagram allows a 2-conductor coil cord.
A different C182 length may be acceptable only when the conductor count, jacket style, cord travel, door or gate movement, and terminal layout all fit the installation without stretching or dragging the cord.
The main risk is matching only the wire count while missing the expanded length, jacket type, monitoring configuration, or existing part number. Compare the original cord marking and parts diagram before replacement.
