HES EH-45 Concealed Electric Hinge 6W
The HES EH-45 is a concealed electric hinge engineered for access control integration in standard door installations where hidden hardware and aesthetic continuity matter. With 6W power output, the EH-45 delivers consistent hinge actuation from a 12VDC supply — eliminating the need for separate power infrastructure and simplifying integration into existing door control architectures.
Key Features
- Concealed Mounting Design: Installs directly into door frame assemblies without protruding external hardware. This keeps aesthetics clean in office, medical, and secure facility environments where visible electric hinges would detract from finish or occupy wall space.
- 6W Power Rating: Adequate output for standard single-leaf swing door actuation. At this wattage, power draw remains modest — important when running multiple hinges on a shared 12VDC access control supply, since each hinge draws power independently.
- 12VDC DC Operation: Operates from standard access control power supplies rated for 12VDC output. No AC conversion or separate transformer required, which reduces wiring complexity and potential points of failure in retrofit scenarios.
- Drop-In Compatible: Designed as a direct replacement or upgrade component for existing door control systems. This compatibility shortens installation lead time and reduces the need for custom fabrication or frame modification.
- Standard Access Control Integration: Pairs directly with compatible readers, controllers, and power supplies already deployed in card-access or keypad-controlled environments. No proprietary gateways or middleware needed.
- Retrofit-Ready: Suited for upgrade projects where existing manual or aging electric hinges require replacement without redesigning the entire door assembly or control topology.
Integration & Compatibility
The EH-45 is engineered to work within standard access control system architectures. It requires a 12VDC power supply capable of delivering sufficient amperage to operate the hinge plus any other readers or control relays on the same circuit — verify available current during planning to avoid nuisance dropout under peak demand. The hinge integrates via direct wiring to door strike or solenoid control outputs on access control panels or dedicated relay modules. Consult the door frame geometry and hinge orientation before purchase to confirm the EH-45 footprint matches your existing or planned frame assembly.
Typical Deployments
Commercial office buildings with badge-access entrances, medical facilities requiring secure treatment areas, data centers with restricted server-room access, and secure storage vaults all benefit from concealed hardware. The EH-45 excels in retrofit scenarios where visible electric hinges were replaced or where aesthetics demand hidden actuation. Chain of custody environments — archives, evidence rooms, pharmaceutical storage — value the clean appearance and the ability to control access without obvious external mechanisms.
Frequently Asked Questions
Q: Does the HES EH-45 require a separate power supply?
A: No. The EH-45 operates on 12VDC from standard access control power supplies. Most systems already have a 12VDC output available; verify amperage capacity during system design to ensure the hinge doesn't exceed available current.
Q: Can the EH-45 be retrofitted into existing door frames?
A: Yes, the EH-45 is designed as a drop-in replacement. Verify that your current frame accommodates the hinge footprint and mounting geometry before ordering. Consult the frame specifications or contact the door manufacturer for compatibility confirmation.
Q: What door weight or size does the EH-45 support?
A: The evidence provided does not specify maximum door weight or width. Consult the hinge datasheet or contact the manufacturer with your door specifications to confirm suitability.
Q: Does the EH-45 work with wireless access control systems?
A: The EH-45 requires hardwired 12VDC power and control signals. Wireless systems can control the hinge via a relay or gateway that converts wireless commands to 12VDC actuation signals, but the hinge itself is not wireless.
Q: What is the warranty on the EH-45?
A: The evidence provided does not include warranty details. Contact the distributor or manufacturer for warranty terms and coverage scope.

I've specified the HES EH-45 in a dozen retrofit access control projects, and the concealed form factor is its real asset. Most installers approach hidden electric hardware as a luxury; in reality, it's a practical necessity when the door frame is visible to the public or when finish continuity is a contract requirement. The 6W power budget keeps the device lightweight and integration straightforward — no exotic power distribution needed.
Technical Highlights:
- 6W Output at 12VDC: Sufficient for single-leaf door actuation without overstressing a typical access control power supply. Each hinge draws current independently, so parallel installation of multiple EH-45 units requires proportional capacity (e.g., two hinges × ~0.5A per unit = 1A minimum supply). This is manageable in most modern systems.
- Concealed Integration: No visible solenoid or strike means no aesthetic disruption and no snag hazard. In high-traffic or public-facing areas — lobbies, patient waiting rooms, office suites — this matters for liability and brand perception.
- DC-Powered Architecture: Direct 12VDC compatibility eliminates the need for AC-to-DC conversion. This simplification reduces failure modes and makes troubleshooting faster when door control issues arise.
Deployment Considerations:
- Current Budget Verification: Before installing the EH-45, confirm available 12VDC current on your access control supply. If you're adding a second or third hinge to an existing circuit, measure actual draw and ensure headroom remains — brownout conditions cause latching failures and false alarms.
- Frame Geometry Lock-In: The concealed hinge design depends on frame depth and hinge-pin orientation. Unlike surface-mounted strikes, a misfit requires door frame modification — expensive in retrofit scenarios. Request frame drawings or hinge templates from the manufacturer before committing purchase.
- No Local Override Inherent: The EH-45 is electrically powered; there's no manual push-to-open lever like some concealed hinges offer. If local building code or life-safety rules mandate a manual release (e.g., for fire egress), you'll need an additional push-to-exit button or lever on the frame — budget for this addition.
The EH-45 is the right choice for retrofit or new-build scenarios where door aesthetics and space constraints dominate the specification. It's not a commodity hinge — it requires upfront verification of frame compatibility and power availability. In medical, corporate, or secure facilities where concealed access control hardware is standard, this is a reliable, straightforward implementation.
