Mini connector / in-line, 4-pin,

The THB.391.A4A mini connector is a 4-pin circular connector from Binder’s TH391 series, featuring a compact in-line design. This design allows for a particularly space-saving installation and is ideal for applications where several signals need to be transmitted in parallel.

The 4-pin configuration enables the transmission of stereo audio signals with separate earth connections, composite video signals with additional control lines, or the distribution of several independent signals via a single compact connector. The mini design significantly reduces the space required and facilitates integration into confined installation spaces.

Electrical connections are made via soldered or crimped terminals, which ensure a durable and vibration-resistant connection. The in-line design allows for continuous cable routing without any lateral spacing, which is particularly advantageous in cable entries and distribution boxes.

Typical applications include audio-visual installations, multimedia technology, conference room systems, industrial camera systems, signal distribution in control systems, and mobile entertainment systems, where compact and reliable multi-point connections are required.
