Simplify the wiring of electrified commercial door hardware with the McKinney QC-C300P ElectroLynx Retrofit Cable.

Designed for retrofit and field-installed electrified openings, the QC-C300P provides a 38-inch, 12-conductor wiring harness with an ElectroLynx Molex connector on one end and pinned conductors on the opposite end.

The cable is typically installed between an ElectroLynx electrified hinge and the electrified lockset, exit device, or trim located inside the door.

ElectroLynx Quick-Connect System

ElectroLynx is ASSA ABLOY's universal quick-connect system for electrified door openings.

Instead of requiring installers to splice every connection directly at the hinge, compatible ElectroLynx hardware uses plug-style connections to simplify installation, servicing, and hardware replacement.

ElectroLynx technology is used across multiple ASSA ABLOY commercial hardware brands.

Typical Application

The QC-C300P is typically routed:

From the electrified hinge → through the door → to the lockset or exit-device trim

Common applications include:

• Electrified mortise locks

• Electrified cylindrical locks

• Electrified exit-device trim

• Access-control hardware

• Request-to-Exit devices

• Door-monitoring systems

• Electrified commercial door openings

38" Cable Length

Actual Cable Length: 38"

The 38" configuration is designed for common wiring runs from the hinge side of the door to electrified hardware installed farther into the door leaf.

McKinney offers other ElectroLynx retrofit cable lengths for different installation requirements.

Molex to Pinned Configuration

The P suffix is important when selecting this cable.

QC-C300P

• 38" cable

• 12 conductors

• Molex connector on one end

• Pinned conductors on the other end

QC-C300

• 38" cable

• 12 conductors

• Molex connectors on both ends

Choose QC-C300P when the field installation requires a quick-connect interface at one end and individual pinned connections at the opposite end.

Retrofit Applications

McKinney specifies ElectroLynx retrofit cables for openings where the door was not supplied from the factory with the ElectroLynx wiring harness already installed.

This makes the QC-C300P particularly useful for:

• Existing-door electrification

• Access-control upgrades

• Replacement door installations

• Electrified hardware retrofits

• Field-installed electric hinges

• Hardware conversions

• Service and repair applications

Compatible Hardware Systems

ElectroLynx technology is used on compatible electrified hardware from ASSA ABLOY brands including:

• McKinney

• Adams Rite

• Corbin Russwin

• HES

• Norton Rixson

• SARGENT

• Securitron

• Yale

Actual compatibility depends on the connectors, conductor requirements, and electrified hardware being installed.
