DB25 Male To Female Extension Cable
PCM Cable Co., Ltd. is one of the leading db25 male to female extension cable manufacturers and suppliers in China. Welcome to wholesale high quality customized products at discount price from our factory. Contact us for quotation and free sample.
Premier Cable PCM-0968 is a DB25 Male to Female Extension Cable developed for industrial systems where existing D-Sub ports need additional reach, easier rear-panel access, or routing between equipment cabinets.
Featuring one standard 25-pin D-Sub male connector and one DB25 female connector, PCM-0968 extends an existing DB25 interface to a more accessible location without changing the original connector gender at the remote end.
Unlike general-purpose DB25 cords, PCM-0968 is positioned for industrial automation, DAQ, CNC motion control, and ATE applications. Its male-to-female extension architecture allows multiple I/O, control, feedback, or communication circuits to be relocated as one organized cable assembly, reducing field rewiring during system upgrades and equipment rearrangement.

Product Features
● DB25 Male-to-Female Linear Layout
Symmetrical 25-pin matrix utilizes true 1-to-1 pinouts to establish a seamless hardware-level linear relay for underlying buses.
● Dense Braid-Plus-Foil Multi-Shielding Network
High-coverage copper braid covers metallic Mylar wraps to forge a low-impedance closed anti-noise continuous network against high-frequency spikes.
● Knurled Thumbscrews & Integrated Hex Nut Hardware
Outfitted with extended thumbscrews on male and hex locking nuts on female to allow versatile inline couplings or chassis flush-mounting.
● Micro-Inch Wear-Resistant Gold-Plated Receptacles
Contact blades undergo a precision micro-inch heavy gold-plating line, ensuring zero contact resistance drift after thousands of mating cycles.
Core Application Scenarios
Industrial Through-Wall Routing
Designed for laboratory test rooms, industrial enclosures, automation cabinets, and enclosed production areas, this DB25 extension cable routes existing interfaces through panels, partitions, or cable channels to accessible operating zones. The male-to-female architecture supports centralized serial/parallel communication, multi-channel I/O, control, and feedback signals without changing the original interface format. Shielded construction also helps reduce EMI/RFI coupling in electrically noisy industrial environments, improving connection stability and maintenance efficiency across separated equipment areas.
ATE Semiconductor Test Fixtures
Suitable for IC handlers, semiconductor ATE platforms, large-scale functional testers, burn-in racks, and automated test fixtures, this DB25 cable extends the host or controller interface to the frequently accessed fixture side. Operators can connect and disconnect the extension end during DUT or fixture changes instead of repeatedly mating the costly tester-board connector, helping reduce connector wear, pin damage, and maintenance risk. It also brings multiple trigger, control, status, and test signals closer to the workstation for faster fixture changes, troubleshooting, and production-line servicing.
Frequently Asked Questions
Q1: Ordinary repeater extension cables often slip at the connection point due to worker pulling orvibration; how does this PCM-0968 male-female extension cable maintain locking?
A1： This is precisely the technical emphasis behind our stable connection matrixand core advantages. Low-cost alternative male-female cords lack structural lockinghardware. As Premier Cable's newly developed product, the PCM-0968 deploys aphysical dual-locking mechanism at the inline relay node utilizing a knurledthumbscrews & integrated hex nut hardware system. Once mated, pulling forcesand rotational stresses are entirely diffused by the steel face brackets and our hermeticovermolded backshell manufacturing process backshells, isolating interior solderpoints. This configuration holds internal leaf nodes immobile during heavy manualhandling or constant floor vibration cycles to maintain zero-dropout reliability.
Q2: After extending the dense 25-pin cable, how can we ensure that signals across all channels do notsuffer severe intermodulation and insertion loss under long-distance transmission?
A2：Our fundamental focus revolves around solving long-distance microwavesignal attenuation and adjacent signal cross-talk. Because extending 25-pin matricestriggers immense capacitive and inductive parasitic leaks that prompt packet loss,Premier Cable implements optimized characteristic impedance balance andconsistency calibration algorithms. We select premium low-resistance oxygen-freecopper conductors laid out via calculated, staggered geometric pitch twisting to balancemutual electromagnetic fields. Furthermore, both connection faces undergo 360-degreeshielding braid-to-shell welding to establish a robust dense braid-plus-foil multi-shielding network. This closed-loop shield intercepts factory transient spikes, ensuringhigh signal fidelity and crisp pulse edge retention across long extension lengths forzero-drop metrics
Q3: Why is it recommended to choose shielded versions for industrial environments?
A3:Industrial environments contain VFDs, motors, relays, and switching supplies. Shielding helps reduceEMI/RFI coupling into internal signal circuits.
