Pin-in-Pin Magnetic and Floating Pin Double Cylinder Lock

The pin-in-pin double cylinder features a solid brass construction and an advanced hybrid pin tumbler mechanism combining 5×2 telescopic pins (Φ4.0 mm outer and Φ2.0 mm inner), 1 magnetic pin, and 1 floating pin. Operating with dimple keys, it is certified according to the EN 1303 standard and tested for a durability of 100,000 cycles. Standard physical configurations include anti-drilling pins in the housing and plug, along with specialized anti-picking structures on driver pins 3 and 4. Available for commercial B2B procurement with optional master key systems.

Core Configurations & Applications

Hardware Specifications

  • Triple-Action Pin Architecture: Features 5 external key pins (Φ4.0 mm) paired with 5 internal key pins (Φ2.0 mm), 1 magnetic pin, and 1 floating pin, operating against 5 driver pins (Φ4.0 mm). The pin step is 0.5 mm, with pin lengths of 5.2, 5.65, 6.15, and 6.65 mm. The driver pin hole diameter is calibrated to Φ4.2 mm.
  • Multi-Point Anti-Picking Protection: Incorporates combination spool key pins, complemented by driver pins #3 and #4 engineered with dedicated anti-picking structures.
  • Anti-Drilling Components: Standard physical anti-drilling pins installed in the housing (1 pin per side, Φ1.5 x 15 mm) and in the brass plug (1 pin per side, Φ1.5 x 4 mm).
  • Clutch and Gear Mechanism: Incorporates a powder metallurgy iron-based clutch and an optional 10-teeth gear.
  • Active Interaction Dimple Keys: Supplied with 5 dimple keys with H11 plastic heads, selectable in nickel silver or full brass, featuring embedded magnetic elements and active floating elements to align with internal pins.

Primary Application Environments

  • High-Security Commercial Entrances: Designed for critical perimeter doors requiring double-sided key operation with simultaneous mechanical, magnetic, and floating pin verification.
  • Critical Infrastructure & Server Rooms: Suitable for access control points requiring strict physical key duplication protection.
  • Institutional Facilities: Applicable for institutional complexes requiring integration into structured Master Key Systems or staged construction key setups.

Optional Configurations & Key Systems

Optional Hardware Features

Based on project specifications, the following options can be added:

  • Construction Key Option: Keying configuration enabling temporary contractor access during construction, disabled upon first use of the master/owner key.
  • Anti-Bumping: Optional internal pin configuration.
  • Anti-Snap (Sacrificial Cut): Optional grooved design specifying breaking points.
  • Anti-Breaking: Optional reinforced structural additions.
  • Double-Entry Function: Optional mechanism allowing external key operation while a key is engaged on the inside.

Keying Platforms

  • Keyed Different (KD): Each lock cylinder operates with an independent set of keys.
  • Keyed Alike (KA): Multiple cylinders operate with a single key.
  • Master Key System (MKS): Multi-tier master key configurations for facility management.

B2B Procurement & Export Terms

  • Minimum Order Quantity (MOQ): Please consult our commercial department for specific finish, length, and upgrade combinations.
  • Production Lead Time: Dependent on order volume and master keying specifications (typically 30 to 45 days).
  • Samples: Physical cylinder prototypes are available for fitment testing and evaluation.
  • Incoterms & Shipping: FOB Ningbo, Shanghai, or Tianjin. Packaged in standard industrial cartons.
  • Technical Data: 2D and 3D CAD files are available for OEM partners to assist with lockcase integration.

Manufacturing Information

Beijing Oupuoptic Instrument Co., Ltd. was founded in Tongzhou District, Beijing, in 2001. In 2019, the company expanded operations by establishing Zhejiang Guocheng Technology Co., Ltd. in Zhejiang province, which includes a dedicated lock cylinder manufacturing facility.

  • Manufacturing Facility: A 5,000-square-meter facility equipped for lock cylinder and hardware production.
  • Workforce: Supported by a dedicated team of over 100 professionals.
  • Quality System: Operations are conducted under the ISO9001 international quality system certification.
  • Product Focus: The lock factory specializes in independent research, product design, and the precision manufacturing of European and American standard lock cylinders.

Frequently Asked Questions

The cylinder utilizes a triple locking principle. The lock plug can only rotate when the dimple key aligns the concentric inner and outer telescopic pins (5 pairs) at the shear line, interacts with the internal magnetic pin via the key’s magnetic element, and correctly actuates the active floating pin simultaneously.

Standard hardware includes physical anti-drilling pins in both the housing (Φ1.5 x 15 mm) and plug (Φ1.5 x 4 mm), combination spool key pins, and specialized anti-picking driver pins (#3 and #4).

No. Physical anti-drilling pins, combination spool key pins, and the hybrid pin mechanism are standard. Anti-snap (sacrificial cuts), anti-bumping, anti-breaking, and construction key systems are available as optional configurations upon request.

Yes, the 5×2 telescopic, magnetic, and floating pin configuration supports Master Key Systems. Contact our engineering department with your keying matrix for specifications.
