Description
Norcomp DB25 Female-to-Female Dual Connector 0.750" Spacing PCB Mount 178-025-512-571
This is a Norcomp 178-025-512-571 dual stacked DB25 female-to-female connector designed for PCB through-hole mounting. It pairs two DB25 (25-pin D-sub) female receptacles side by side in a single body, with a 0.750-inch center-to-center spacing between the two connectors and through-hole solder pins extending from the base for direct board mounting. The metal shell is nickel-plated. This configuration allows a single PCB footprint to provide two DB25 female ports — a compact solution for applications requiring dual RS-232 or parallel connections on one assembly.

Applications
DB25 D-sub connectors are a long-established standard in serial and parallel data interfacing, originally defined under the RS-232 and IEEE 1284 standards. The dual stacked PCB-mount format of this Norcomp part is used in equipment that needs to present two DB25 ports from a single board location — common in audio/video production gear, industrial controllers, test systems, and custom embedded hardware. The bag label on this lot identifies it as a part ordered by 360 Systems, a manufacturer known for professional digital audio devices, consistent with the original listing note about high-end sound equipment manufacturing. These connectors are still in active use today wherever RS-232 serial or 25-pin parallel interfaces are required on custom PCBs or repair/replacement work.
This Norcomp 178-025-512-571 DB25 female-to-female dual stacked connector is new old stock. The bag label (visible in photos) is dated February 2005 and shows a quantity of 25 pieces from a 360 Systems manufacturing lot. The connector itself is unused and shows no wear. It may be out of the original manufacturer's packaging. Listing is for a single dual-connector unit as shown in the photos. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
