1.6/5.6 (L9) PCB Connectors are compact RF coaxial connectors designed for direct mounting onto printed circuit boards, providing a fixed interface between the board-level circuit and external coaxial cable. Built on the 1.6/5.6 DIN interface standard, this connector series maintains stable 75Ω impedance and is engineered for space-constrained board layouts commonly found in video processing modules, CCTV equipment, and telecommunication transmission circuits. 1.6/5.6 (L9) PCB Connectors are typically soldered directly onto the board through-hole or surface pads, forming a mechanically fixed and electrically stable connection point for signal input or output.
Compared with cable-mount or panel-mount connectors, 1.6/5.6 (L9) PCB Connectors integrate directly into the board assembly process, eliminating the need for a separate cable segment between the board and the connector interface. This mounting method reduces signal path length and associated insertion loss, which is beneficial in compact video and RF circuit designs where board space and signal integrity are both important considerations. Contact components in this category are typically machined from brass or phosphor bronze and finished with gold or nickel plating to meet solderability and conductivity requirements.

Application Scenarios and Selection Points
1.6/5.6 (L9) PCB Connectors are applied in CCTV camera modules, video distribution boards, telecommunication transmission circuits, and other compact RF or video circuits where a direct board-level coaxial interface is required. When selecting a connector from this category, the following points are recommended for confirmation:
- Mounting orientation — straight or right-angle, based on the board layout and enclosure height
- Mounting method — through-hole or surface mount, matched to the board assembly process
- Impedance matching — 75Ω configuration confirmed against the video or data transmission system requirements
- Plating material — gold plating for improved solderability and conductivity, nickel plating for general durability
- Mechanical fixation requirement — flange-type PCB connectors recommended where additional panel support is needed
