Vszerda DB9 RS232 serial cable adapter with case and long bolts

SKU CH-X5RG-0Y5D9

DB9 male-to-female adapter with screw terminals, insulated ABS case and long mounting bolts

  • Solderless wiring with screw terminals for 12-24AWG cable
  • Insulated ABS+PC case with anti-slip finish protects connections
  • Male DB9 plug with nickel-plated copper pins for RS232 links
  • Multiple cable-entry holes from .2 to .4 inch diameter
  • Compact 58 x 35 x 21 mm footprint fits tight panels

DB9 RS232 Screw-Terminal Adapter

This DB9 breakout adapter converts a standard 9-pin serial port to screw terminals for solderless wiring. It ships new in a protective ABS-PC case with long mounting bolts and three dust covers. The copper-base contacts are nickel-plated for reliable signal continuity across industrial and legacy equipment.

Installers needing quick field termination

Technicians maintaining RS232 links on PLCs, CNC machines or legacy networking gear will appreciate the tool-free screw clamps accepting 12-24 AWG solid or stranded wire. The compact 58 x 35 x 21 mm footprint fits tight panels, while the 5-10 mm cable-entry options suit various jacket diameters. Users requiring gender changers, right-angle profiles or IDC insulation-displacement contacts should consider other form factors.

Solderless screw-terminal block for 12-24 AWG

The decisive spec is the solderless screw-terminal block that accepts 12-24 AWG conductors directly onto nickel-plated copper pins. This eliminates crimping tools and solder joints, allowing rapid rewiring in the field while maintaining a secure gas-tight connection rated for repeated mate cycles.

Questions about this item

What is the maximum wire gauge the screw terminals can accept?

The screw terminals accept wires from 12 to 24 AWG according to the product name, while the detailed information lists a 26 to 16 AWG range.

How much heat does the adapter generate during continuous RS232 communication?

The adapter is a passive copper and brass assembly with no active components, so it produces no measurable heat during normal serial data transmission.

Does the DB9 adapter require any external power supply or driver installation to operate?

No external power or driver is needed; the unit is a purely mechanical solderless breakout that connects the DB9 pins directly to the screw terminals.
