D-configuration Connectors for Digital Broadcasting Equipment
DXLM Series
Accepts panel thickness up to 3 mm
DXM Series
(Panel thickness up to 1.6 mm thick)
DXLM Series
Features
1. Increased range of the mounting panel thickness
Extension of the mating and locking area by 1.5 mm has
allowed the DXLM Series to be mounted on panels up to
3mm thick.
2. Effective protection against electrostatic discharge
Unique Hirose Electric design makes reliable ground
connection in sequence, with metal shell first, then the
board circuit.
3. Temporary board holding feature
Deflecting force of the side protrusion of the insulator’s
posts against the walls of holes provides superior retention
to the board, preventing leaning forward during handling.
4. Superior stability and retention to the board
Solid metal grounding posts are soldered to the board.
This creates extremely strong retention to the board,
allowing the assembly to retain reliable connections, even
when large forces are applied when miss-mating or pulling.
5. RC-5237, EIAJ Standard
Conforms to the requirements for D-configuration
connector used in connections for digital image broadcast.
Applications
TV, STB, DVD, LCD TV and other equipment supporting digital
broadcasts
Effective protection against electrostatic discharge
