Deltaco DEL-94 wire connector DB9ho-ho

The Deltaco DEL-94 wire connector DB9ho-ho is a DB9 female-to-female connector designed to provide a stable serial connection between devices that use a 9-pin D-sub interface. The connector is intended for signal and data transmission in computing and communication equipment, offering a compact inline solution for extending or joining DB9 cabling without soldering. The construction emphasizes contact alignment and mechanical security to maintain consistent electrical contact under normal operating conditions.

Advantages

The connector offers a straightforward method to couple two DB9 cables while preserving pin mapping and signal integrity. Its compact form factor reduces strain on connected cables and simplifies installation in confined spaces. The product is made to withstand repeated mating cycles and maintain reliable contact, which helps reduce intermittent connection issues often caused by loose or corroded terminals.

Suitable for

• Extending or joining RS-232 serial cables
• Connecting legacy computer peripherals such as mice, modems, or industrial controllers
• Field repairs and temporary cable extensions in workshops or server rooms
• Prototyping and testing serial communication links

Key specifications

• Connector type: DB9 female-to-female (9-pin D-sub)
• Contact arrangement: 9 contacts preserving standard RS-232 pinout
• Mechanical format: inline coupler for two DB9 cables
• Contact material: metal contacts for electrical conductivity
• Body material: durable insulating housing for mechanical protection

How to use

To use the DB9ho-ho connector, align each DB9 cable plug with the corresponding female ends and insert until the connectors seat fully. If the cables or devices use screw-locking thumbscrews, secure them to prevent accidental disconnection. Verify the pinout compatibility of the connected cables and devices before powering equipment to avoid signal conflicts. After installation, test the serial link using appropriate software or diagnostic tools to confirm proper communication.

Usage recommendations

Use the connector in dry indoor environments and avoid exposing it to excessive mechanical stress or corrosive conditions. Check contacts periodically for signs of wear or oxidation and replace the connector if connections become intermittent. For permanent or critical installations, consider using shielded cabling and properly grounded systems to minimize interference.
