EFB ELEKTRONIK E-57/50 MO 50-Pin Right-Angle Centronics Male Connector for Octopus Cables

In server rooms and industrial data closets, technicians often need to build custom octopus cables for SCSI-1 peripheral interconnections. The EFB ELEKTRONIK E-57/50 MO Centronics connector is the right choice for such tasks. This 50-pin male connector features a right-angle (90°) cable exit, making it ideal for tight spaces behind equipment racks or inside enclosures. Its solder termination allows for reliable, permanent connections, while the metal shell provides shielding against electromagnetic interference. Whether you're fabricating a multi-device SCSI cable or repairing an existing harness, this connector ensures a secure and durable link.

Key specifications

• Connector type: Centronics, 50-pin male
• Orientation: Right-angle (90°) for space-saving cable routing
• Termination: Solder cups for robust wire attachment
• Material: PBT housing, copper alloy contacts with gold flash over nickel
• Electrical ratings: 1 A per contact, 250 V AC, insulation resistance >1000 MΩ
• Operating temperature: -25°C to +85°C
• Shielding: Metal shell for EMI protection
• Compatibility: SCSI-1 and similar 50-pin Centronics interfaces

Why choose it

This connector is engineered for reliability in data communication and peripheral interconnection. The right-angle design reduces strain on the cable and allows for neat cable management in confined spaces. Gold flash contacts ensure low contact resistance and long-term corrosion resistance. The PBT housing withstands mechanical stress and high temperatures, making it suitable for industrial environments. Its solder termination provides a permanent, vibration-resistant connection, essential for mission-critical systems.

Ideal use cases

• Building custom octopus cables for SCSI-1 peripherals
• Repairing or extending legacy Centronics 50-pin cables
• Industrial automation and data acquisition systems
• Test and measurement equipment interconnects
• Server and storage device connections in tight racks

Good to know

The E-57 series from EFB ELEKTRONIK is known for its quality and compatibility. This connector is a cable-mount component, meaning it is designed to be soldered directly to wires, not mounted on a PCB. It is not a complete cable assembly; you will need appropriate 50-conductor cable and soldering skills. The metal shell provides grounding and shielding, but ensure proper cable shield termination for optimal performance. For high-volume production, consider using a crimp version if available, but for prototyping and repairs, solder termination is often preferred.
