MDM-25SH023M5

Introduction

The MDM-25SH023M5 is a D-Sub cable used for military and aerospaceapplications. It is a straight-mated connector that is frequently usedin power, signal, and data transmission applications, and is typicallyused for high-speed, high-power, and low-power applications.It features a 4-pin header, a lug, 2 contact pins, and an O-ring thathelps to keep the connector secure. This cable has a low insertionforce and is rated for a current range of 0.0125 Amp to 60 Amps(maximum). Additionally, it is capable of holding up to 10,000volts. It is also ideal for use in environments where vibration couldbe a factor, as it is designed to meet the requirements of MIL-S-83731.

Applications

The MDM-25SH023M5 is most commonly used in military and aerospace applications. It isused in applications such as connecting communications equipment,satellite data links, aircraft, ships, and ground stations. It is also used toconnect aircraft instruments to convey energy, control signals, andother information from one device to another.The cable is also suitable for use in industrial and civilianapplications where vibration, extreme environmental conditions, orhigh-power requirements are expected. These applications includeconnecting to power supplies, antennas, sensors, electric motors,transmitters, and other high-power or low-power applications.

Working Principle

The MDM-25SH023M5 is a straight-mated D-Sub cable that works on theprinciple of linear force. The contact pins create an electricalconnection when pressure is applied to them. The pin connections aresecured using an O-ring, which provides additional protection againstvibration or shock, while ensuring a solid electrical connection. Thisconnection is created by the interaction between the conductiveportion of the contacts and the non-conductive portion of the O-ring.The contact pins of the cable are spring-loaded and are designed toprovide better contact in the areas with high vibration or shock. Thespring-loaded contacts help to reduce contact resistance, which helpsto ensure a reliable connection.

Operating Temperature

The MDM-25SH023M5 is designed to be reliable and resilient in a wide variety of environments.It has an operating temperature range of -55°C to +125°C and can withstand a temperature shock of -55°Cand +85°C. Additionally, it is capable of withstanding up to 1,000 cycles of salt-spraytesting without deterioration of the contacts and O-ring.

Conclusion

The MDM-25SH023M5 is a straight-mated D-Sub cable used widely in the military and aerospaceindustries. It is designed for high-speed, high-power, and low-power applications and is suitedto environments where vibration, shock, extreme temperatures, and salt-spray are present. Thecable features a 4-pin header, a lug, 2 contact pins, and an O-ring for added security.
