1.6/5.6

1.6/5.6 series (often called DIN 1.6/5.6) are a 75 Ω connector with a 1 GHz cutoff, covered by the DIN 47295 standard. 1.6/5.6 RF connectors are characterised by high mechanical and electrical stability. There are several subtypes featuring different coupling mechanisms, listed below. It should be noted however that not all manufacturers produce all subtypes.

• Type A - Screw-on mechanism with coupling nut
• Type C - Slide-on coupling with centering sleeve
• Type E - Snap-on coupling with retention clip
• Type F - Quick lock

History

The 1.6/5.6 connector series was introduced to the European telecommunications market in the late 1970s under the DIN 47295 and IEC 60169-13 standards to support an increasing demand for high density applications unsuitable for older connectors like BNC.

Applications

The 1.6/5.6 series is a miniature European design that permits dense connector packing, making them ideal solutions for applications where space limitation is a factor. With a 1 GHz maximum operating frequency, applications are limited to lower frequency 75 Ω radio transmissions such as CATV telecom, and CCTV distribution. The series is not particularly common due to the introduction of a 40% smaller 75 Ω 1.0/2.3 connector variant.
