Product Features
-
Half-Pitch D-Sub Structure:
Features a standard 1.27mm center pitch, significantly smaller than traditional D-Subs, enabling high-density parallel connections in restricted spaces.
-
Double-Row 34-Pin Precision Layout:
Utilizes a symmetrical dual-row design (34 pins each), ensuring orderly alignment and reducing mechanical stress during insertion to prevent misalignment.
-
D-Shaped Metal Shell Protection:
The classic D-sub interface offers mechanical polarization, while the rugged metal shield provides a physical barrier against impact.
-
High-Heat Grade PBT Insulator:
Constructed with reinforced PBT for superior electrical insulation and thermal stability, ensuring the base remains intact during soldering.
Core Application Scenarios
Legacy Mainframe Maintenance
The PCM-TAT-0003 68 Pin HPDB Connector is suitable for legacy mainframe systems, older servers and legacy storage maintenance applications. Many industrial, financial and research organizations continue to operate SCSI-based equipment that requires reliable replacement connectivity for system upgrades and data migration. Compatible with Wide SCSI applications, this HPDB Connector helps engineers connect legacy storage devices, backup systems and migration platforms, extending equipment lifetime while reducing modernization costs.
Medical Imaging & Diagnostic Equipment
The PCM-TAT-0003 68 Pin HPDB Connector can be used in large medical imaging systems, including CT scanners, MRI systems, medical data processing workstations and professional diagnostic equipment. Medical imaging platforms require reliable transmission of large amounts of image data and control signals. With its high-density parallel interface design, the HPDB 68 Pin Connector supports multi-channel data exchange between control units, acquisition modules and storage systems, helping medical equipment manufacturers achieve stable internal connectivity.
Core Performance Advantages
16-Bit Wide Bus Compatibility:
Specifically optimized for Wide SCSI protocols, delivering higher instantaneous data throughput than legacy 8-bit interfaces.
Omni-directional EMI Shielding:
When paired with metal backshells, it provides near-100% EMI protection, shielding mission-critical systems from RF interference.
Minimized Crosstalk Interference:
The internal pin configuration is optimized to suppress inter-channel interference during parallel high-speed signal transmission.
Long-term Electrical Contact Stability:
Thick gold plating on contacts ensures contact resistance remains minimal over years of uninterrupted service.
Frequently Asked Questions
Q1: Is HPDB 68 the same as what is commonly called an HD68 connector?
A1: Yes, HPDB 68 is often referred to as HD68 (High-Density 68) or SCSI-2 connector, denoting the same 1.27mm pitch D-style interface.
Q2: Can I solder 24AWG cable directly to it?
A2: Given the tight pitch, we recommend 28AWG or 30AWG wire. 24AWG may be too thick for these high-density solder buckets.
Q3: Does it support high-speed SCSI-3 Ultra modes?
A3: Yes, the electrical design supports protocols like SCSI-3 Ultra 160/320, provided that high-quality shielded cabling is used.
