Ten DB9 RS-232 adapters for serial projects

This kit supplies ten DB9 male connectors built for RS-232 serial communication. Each unit uses copper contacts and ships in a plastic case for organisation. The parts suit hobbyists, technicians and engineers who need to add or repair legacy COM ports on custom boards or industrial equipment. No drivers are included; the adapters provide the physical interface only.

Sustained signal integrity over copper pins

Copper contacts maintain consistent conductivity during long data sessions without the resistance drift seen in cheaper alloys. The fixed pin layout prevents intermittent disconnects when cables are routed inside enclosures. Builders who require hot-plug cycles or ruggedised locking shells should verify those features separately, as this pack offers straight-through male plugs only.

Questions about this item

How much heat does the 9 Pin copper COM adapter generate when running all day?

The DB9 male connector is a passive copper interface with no active components, so it produces no measurable heat during continuous operation.

What existing port or header must my system already have for this RS232 adapter to work?

You need a free RS232 serial header on the motherboard or an expansion bracket that provides a DB9 male connection for the 10 included adapters.
