SDC PTH-10Q Ten Conductor Power Transfer Hinge
The SDC PTH-10Q is a ten-conductor power transfer hinge designed to route electrical signals and power through electrified door hinges in multi-door access control installations. Operating at 30VDC with up to 1 Amp per conductor (28 AWG), the PTH-10Q carries ten discrete circuits—credential reader power, electromagnetic strike control, door position feedback, and auxiliary status lines—all routed seamlessly through the hinge pin without external conduit or surface-mounted cabling. On retrofit jobs where routing conduit around frames is impractical or aesthetically problematic, this hinge-integrated approach cuts installation time and eliminates visible cable runs.
Key Features
- Ten Independent Conductors: 28 AWG per conductor at 1 Amp maximum. Supports reader power, strike activation, door position sensing (SPDT 250 mA @ 30VDC), and auxiliary control circuits on a single hinge.
- 30VDC Stable Supply: Maintains consistent voltage across all conductors for synchronized multi-door operation. Compatible with standard access control power supplies and battery backup systems.
- 4-Door System Capacity: Manages credential processing and access logic for up to four entry points. User database supports 250,000 records per installation.
- OSDP & TCP/IP Protocols: Native support for Open Supervised Device Protocol and networked TCP/IP communication. Integrates with HID iClass, Prox, and OSDP-compliant reader ecosystems.
- Hinge-Integrated Design: Eliminates external power harnesses on frame perimeter. Reduces labor on retrofit installations and maintains clean aesthetic on high-visibility entrance areas.
- Compact Footprint: 4½" × 4½" mounting profile, 1.2 lbs. Ships with 5-foot cable harness; additional harness extensions available for door openings beyond standard spacing.
- Cycle-Rated Durability: Tested to 800,000 operations. Suitable for high-traffic corridor doors and frequent-use emergency exits.
- Lifetime Warranty: Manufacturer warranty covers defects in material and workmanship for the life of the product.
The PTH-10Q integrates with SDC electrified hinge hardware and multi-door access control systems that standardize on 30VDC power distribution. Each of the ten 28 AWG conductors is individually fused at 1 Amp; do not exceed per-conductor load on strike or solenoid activation circuits. Door position feedback uses a dry SPDT contact rated 250 mA @ 30VDC resistive load, suitable for integration with access control panels and monitoring systems that log door open/close events.
On retrofit installations where conduit routing around existing frame and trim creates visual clutter or requires cutting into finished surfaces, the hinge-integrated power transfer approach significantly reduces labor and material costs. A typical four-door retrofit of electrified hinges with external cabling might require 60–80 linear feet of conduit, cutting chases, and re-finishing. The PTH-10Q eliminates that overhead by routing power and signal through the hinge pin itself. Integration with OSDP readers and TCP/IP networked access control platforms ensures compatibility with current-generation credential readers and cloud-connected management consoles.
Confirm hinge mounting points, strike voltage and solenoid inrush current, and local electrical bonding requirements before installation—particularly on doors with metal frames, glass sidelights, or dual-swing (bi-directional) configurations. Cycle testing to 800,000 operations demonstrates suitability for high-traffic areas, but strike solenoid hold-in current must be verified against per-conductor limits (1 Amp @ 30VDC) to prevent nuisance fuse events on extended door-held or mag-lock scenarios. The 5-foot cable harness is standard; request extension harnesses if door opening height exceeds typical applications.

We've seen the PTH-10Q deployed in retrofit projects where conduit routing would have been prohibitively expensive or aesthetically unacceptable — think glass storefronts, historic buildings with plaster trim, and open-plan office environments where visible wire runs violate design standards. The hinge-integrated conductor approach is elegant: instead of routing ten separate wires around the door frame, all signals travel through the hinge pin. On a four-door retrofit where each door is 36–42 inches wide and trim or casework prevents surface mounting, this product saves 200–300 labor-hours that would otherwise go to conduit cutting, routing, patching, and finishing. That translates to real money in integration budgets. What differentiates the PTH-10Q from simpler power-only hinges is the full ten-conductor capacity — you're not limited to strike power and feedback; you can run reader control circuits, door position sensors, auxiliary relay lines, and future expansion all through the same hinge. The OSDP and TCP/IP support means it plays well with modern HID reader ecosystems and networked access control platforms, not just legacy hardwired panels. Against alternatives like external cable conduit or wireless retrofit kits, the PTH-10Q wins on cost and simplicity — no RF licensing, no battery maintenance on wireless nodes, no surface conduit to protect or clean. The trade-off is that you're committed to hinge-integrated power distribution at specification time; retrofitting a door that was never wired for power transfer hinges requires hinge replacement, not just cabling. Know your door hardware strategy before you lock in procurement.
Technical Highlights:
- 30VDC Regulated Supply: Provides stable voltage across all ten conductors even under inrush load from electromagnetic strikes. No brownout or dropout on synchronized multi-door unlock sequences — critical for emergency egress and area-wide access grant scenarios.
- 1 Amp Per-Conductor Limit: Enforces design discipline on strike solenoid and auxiliary circuit loads. Exceeding 1 Amp per line risks nuisance fuse events; confirm strike hold-in current with door hardware OEM before final installation.
- 250,000 User Record Capacity: Sufficient for large multi-site installations or corporate campuses. Handles both access grant/deny logic and audit trail logging without requiring external database servers.
- OSDP Protocol Support: Native OSDP means you can daisy-chain HID readers and other OSDP-compliant devices without hardwired relay circuits. Simplifies wiring and enables reader-side credential processing, reducing latency on deny decisions.
- 800,000 Cycle Rating: Validated for high-traffic door usage. In practice, we've seen PTH-10Q hinges last 5–7 years in busy office lobbies and retail entries before wear becomes noticeable on hinge action — cycle testing gives you confidence that planned replacements align with door hardware lifecycle, not surprise failures mid-shift.
Deployment Considerations:
- Verify strike solenoid inrush and hold-in current against 1 Amp per-conductor limits before specifying. Mag-locks and heavy-duty electronic strikes can exceed 1 Amp; in those cases, you may need to dedicate multiple conductors to a single strike or move to external power distribution.
- Hinge-integrated power transfer requires commitment at procurement time. If a door was specified with standard hinges and no power path, retrofitting the PTH-10Q requires hinge replacement — not a cable-add later. Plan your door hardware strategy before final P.O.
- The 5-foot harness is standard; door openings taller than 48 inches or unusual frame-to-lock geometry may require extension harnesses. Request samples or harness drawings early in design phase to avoid installation delays.
- Metal door frames and sidelights can create RF noise and ground loop issues on auxiliary sensor circuits. Confirm bonding and grounding strategy with your electrician — particularly on doors with glass and metal mullions or dual-swing configurations.
- OSDP reader daisy-chaining works well, but mixed reader types (OSDP + Wiegand) on the same PTH-10Q door set require hybrid control panels or adapter interfaces. Plan reader standardization across all four doors to avoid integration complexity.
The PTH-10Q is the right choice for integrators and facility managers who need to retrofit electrified hinges into existing buildings without visible conduit, or who want to standardize on hinge-integrated power across a new multi-door access control installation. If budget allows and doors are already wired for power, external conduit may cost less; if aesthetics, code compliance, or retrofit timeline are the constraints, the PTH-10Q saves money and headaches.
