Connector 7-16 DIN female straight 50 Ω Telegärtner J01121A0177 coaxial

Telegärtner 7-16 DIN female straight 50 Ω connector J01121A0177 is a panel/bulkhead style coaxial interface designed for 50 ohm RF systems. The straight female 7-16 body provides a robust mechanical coupling and low-reflection electrical connection intended for use with antennas, transmitters, base station equipment and RF distribution networks. The connector features a standard 7-16 coupling geometry to mate with compatible male counterparts and is intended for installations requiring a strong, repeatable interface and controlled impedance.

Advantages

This straight 7-16 DIN female connector offers mechanical strength and reliable electrical contact in high-power and dense RF environments. Designed for 50 Ω systems, it supports low VSWR and stable impedance which helps maintain signal integrity. The bulkhead/panel mounting style simplifies integration into racks, enclosures and antenna panels and provides a resilient connection point for routine service and reconfiguration.

Suitable for

• Telecommunications base stations and remote radio heads
• Broadcast transmitters and distribution systems
• Mobile network equipment and antenna feeders
• RF test benches and measurement setups requiring 50 Ω interfaces

When it may not be suitable

This connector is designed specifically for 50 Ω RF applications and the 7-16 DIN coupling; it is not suitable for systems that require other impedances such as 75 Ω or for coax interfaces that use different connector families (e.g., N-type, BNC, SMA). It may also be unnecessary for very low-power consumer equipment where compact miniature connectors are preferred.

Key specifications

• Impedance: 50 Ω
• Connector type: 7-16 DIN female, straight, bulkhead/panel mount
• Coupling: 7-16 screw coupling for secure mechanical connection
• Application: RF/antenna interfaces, transmission and distribution
• Durability: designed for repeated mate/unmate cycles and robust field use

How to use

Install the connector into a prepared panel cut-out and secure it using the provided mounting hardware or the panel’s fastening method. Ensure the mating male 7-16 connector is clean and free of debris before coupling. Align the coupling threads and tighten by hand, then use the appropriate torque procedure if specified by the installation practice to ensure reliable mechanical and electrical contact. Follow standard RF grounding and cable assembly practices when connecting coaxial cables to this bulkhead connector.

What to consider before purchase

• Confirm system impedance is 50 Ω and that mating components use the 7-16 DIN interface
• Verify panel cut-out dimensions and mounting style are compatible with bulkhead installation
• Check environmental and power-handling requirements for your RF installation

Usage recommendations

For reliable performance, use this Telegärtner 7-16 DIN female connector with properly prepared 50 Ω coax and compatible male 7-16 plugs, maintain clean contacts, and follow torque and grounding guidelines during installation to preserve low VSWR and long service life.
