Exclusive Engineering Positioning

This component is a custom-matched alignment guide pin designed specifically for AIRMAX high-speed backplane systems, with a 2.40mm controlled bottom-board thickness as its core unique feature. It completely eliminates pin bending, signal attenuation and assembly rework caused by micro-alignment deviations, and adopts a substrate bottom-side mounting solution to resolve the pain point of cramped routing space on the top layer of PCBs.

Micron-Grade Dimensional Control System

All parameters are formulated in accordance with die-casting drawing standards, enabling full interchangeability and consistent batch production:

• Total length: 32.00±0.5mm; effective pin length: 28.95mm

• Core controlled dimension: 2.40mm (bottom-board compatible, no protrusion interference)

• Pin diameter: Φ5.55mm; step diameter: Φ6.50mm; flange diameter: Φ10.00mm

• Internal thread: M3.5×0.6; lead-in taper: 4.65°; anti-rotation groove: 1.50mm

• General tolerances: .X±0.35 / .XX±0.25 / .XXX±0.15; angle tolerances: 1°–3°

Material Strength & Long-Lasting Protective Performance

• High-pressure zinc alloy die-casting: Uniform structure with no weak points, stable dimensions under repeated thermal cycling

• Chromate conversion coating: Forms a dense oxidation barrier, adaptable to -55°C~125°C operating environments

• Flash-free smooth surface: Passes 6g ring gauge inspection, reduces mating wear and extends connector service life

• Breaking torque: ≥9.2Kgf.cm, resists vibration-induced loosening in harsh working conditions

All-In-One Locking Fastener Solution

Equipped with a full set of fasteners compliant with GB9074.4-88 standards, no additional parts procurement required:

• Matching components: M3.5×6 integrated screw (C1018) + SPCC flat washer + 65Mn spring washer

• Washer specifications: Flat washer 7.0×3.12×0.5mm; spring washer 5.88×3.18×0.9mm

• Drive type: PH NO.2# cross recess, recess depth 1.2–1.4mm, no slippage during assembly

• One-piece locking structure: Stable fastening, avoids assembly deviation caused by loose parts

Bottom-Mount Installation & Compatibility Design

• Exclusive bottom-side substrate mounting: Does not occupy top-layer PCB space, suitable for high-density backplane layouts

• Tapered lead-in structure: Reduces insertion force by approximately 30%, achieves smooth and low-loss mating

• Anti-rotation slot design: Locks with connector structure to prevent rotational misalignment during assembly

• Fully compatible with AIRMAX series connectors, ideal for telecom, data center and industrial control equipment

Compliance, Quality Inspection & Protective Packaging

• Meets RoHS environmental requirements, adapts to global market access standards

• Complies with enterprise standard Q/JYOY JC004, 100% verification of key parameters before shipment

• Packaging: Anti-static blister tray (uniform orientation) + PE bag + desiccant; 250pcs per carton

• Shipping protection: Cross-type PE film bundling + I-shaped carton sealing, moisture-proof and collision-resistant
