SCSI Connector 50 Pin

SCSI Connector 50 Pin

The 50-Pin SCSI (Small Computer System Interface) Connector is a high-density interconnection solution designed for parallel data transmission between computers and peripheral devices. Featuring a compact 1.27mm pitch with precision contacts, these connectors enable reliable communication for storage devices, servers, and industrial equipment requiring robust data transfer. Available in multiple configurations including Centronics type for legacy SCSI-1/SCSI-2 systems, Mini-Centronics for space-constrained applications, and ribbon cable versions for internal connections. The shielded metal shell provides excellent EMI/RFI protection for maintaining signal integrity in electrically noisy environments, while the rugged construction ensures reliable performance through thousands of mating cycles.

Product Selling Points

 

1. High-Density 50-Pin Design with 1.27mm Pitch
Features 50 positions packed at a compact 1.27mm (0.050 inch) pitch - maximizing I/O density in minimal board space. Perfect for industrial controls, test equipment, medical devices, communication systems, and applications requiring numerous signal connections in limited panel area.

2. Wide Voltage Range from 30V to 500V AC
Rated from 30V to 500V AC - accommodating both low-voltage signal transmission and higher-power applications. Contact resistance ≤30 mΩ and insulation resistance ≥1000 MΩ ensure reliable electrical performance across the entire voltage range.

3. Multiple Locking Mechanisms for Secure Retention
Choose from thumbscrew, latch, or friction lock mechanisms to suit your application's vibration and retention requirements. Thumbscrews provide maximum security for high-vibration environments, while latches and friction locks enable quick, tool-free mating and unmating.

4. Durable Shell Materials with Flexible Termination Options
Stainless steel or zinc alloy shell provides excellent mechanical strength and EMI shielding. Available in vertical or right-angle (90°) mounting orientations, with PCB through-hole or solder cup termination styles - offering design flexibility for both PCB-mounted and cable assembly applications.

Star Reviews From Customers

 

1.Michael Chen, Storage Systems Engineer, Data Center Solutions
"Standardized on 50-pin SCSI connectors for our legacy RAID array maintenance. The shielded metal shell eliminates EMI interference in dense server racks, and the gold-plated contacts maintain signal integrity through years of continuous operation. The thumbscrew lock ensures secure connections in high-vibration environments."


2.Sarah Wang, Industrial Controls Designer, Factory Automation
"Essential for our CNC machine interfaces. The right-angle PCB mount version enables clean routing in control cabinets, and the latch lock ensures connections stay secure under continuous machining vibration. The 1.27mm pitch provides the density we need for multiple signal lines in limited panel space."


3.Robert Zhang, Medical Imaging Specialist, Diagnostic Equipment
"Used in our MRI control systems for high-speed data transfer. The full metal shielding prevents interference with sensitive imaging equipment, and the durable construction withstands the demanding hospital environment. The 500V rating provides adequate safety margin for medical applications."
