What Is a Micro DB25 Female to DB25 Male Cable ?
PCM-S-0790 Micro DB25 female to DB25 male cable is a multichannel shielded cable designed to connect different D Sub interface sizes. It uses a compact Micro DB25 female connector on one end and a standard DB25 male connector on the other, with 25 conductors providing corresponding signal transmission.
Unlike a simple adapter, it also provides cable distance and improved connection stability through shielding, a PVC jacket, molded strain relief and locking screws The standard length is 2 meters.
It is suitable for ATE, semiconductor testing, PLC, DCS, test fixtures and industrial automation, especially for equipment upgrades and systems combining Micro DB25 and standard DB25 interfaces.
Main Functions of a Micro DB25 Female to DB25 Male Cable
The Micro DB25 female to DB25 male cable is mainly used for 25-channel signal interconnection between Micro DB25 and standard DB25 equipment. Its 1:1 straight-through wiring provides direct multi-channel signal transmission while converting between the two interfaces.
The 28AWG multicore cable, foil, drain wire and braid shielding help reduce EMI, while molded PVC backshells and locking screws improve connection stability for ATE, semiconductor testing, PLC, DCS and industrial automation systems.
Common issues with Micro DB25 cables.
Vibration and maintenance may loosen connectors. Locking screws and molded strain relief improve connection stability and protection.
Core Product Value
PCM-S-0790
The core advantages of PCM-S-0790 can be summarized as:
◆ High Density Interface Conversion
Micro DB25 and standard DB25 interfaces are integrated into one cable, enabling direct connection between different 25pin formats while reducing extra adapters in high-density and space-limited systems.
◆ 25 Channel Straight Through Wiring
The 28AWG × 25C cable with 25-pin 1:1 wiring carries 25 signal channels while maintaining clear pin mapping, simplifying wiring, commissioning and troubleshooting.
◆ Shielding and Connection Protection
Foil Mylar, drain wire and braid shielding help reduce EMI, while locking screws and molded PVC backshells improve connector retention and mechanical protection.
◆ Easier System Maintenance
The finished cable can be installed, removed, tested and replaced independently without modifying equipment interfaces, making system upgrades, maintenance and spare-part management easier.
