D-Sub connectors are a type of connector widely used in a variety of applications for connecting signals and providing power to a device. MDM-31PSR-A174 is one such connector designed and manufactured for applications of low currents with improved contact protection. It features a snap-in mounting with quick and simple installation.
Applications
The MDM-31PSR-A174 has a wide range of applications in the fields of medical, automotive, industrial electronics, military, transport, computers and telecommunication. The connector is used extensively in applications involving RS-232 and related serial communication protocols, for connecting a host controller (e.g., computer or terminal), a peripheral device (e.g., a modem or printer) and a signal conversion device to transfer data reliably. It can also be used in automatic control process signals and applications requiring data acquisition like industrial robots, CNC equipment, power supplies and other systems.
Working Principle
The MDM-31PSR-A174 connector has a characteristic impedance of about 50 Ω. It uses two metal contact pins for high speed and low noise signal transmission. The SMT pin connectors are designed to reduce crosstalk, and the mating interface has anti-crack features for signal integrity. The contact system is held in place by a spacer that provides vertical stability and spring action. This design improves contact protection and prevents contact damage due to vibration.
The housing of the connector is made from rugged metal casing for reliable operation, and has a snap-lock closure to securely retain the mate. The connector has a dielectric strength of 500V and a humidity of 95 %. The construction and interface of the series are RoHS compliant.
Performance
The MDM-31PSR-A174 connector has a current rating of 1A/1A and a voltage rating of 250V/250V AC. The contact resistance is 5 mΩ and it has a minimum mating cycle of 500 cycles for reliable operations. The contact system ensures reliable operation up to temperatures of -25°C to +85°C. The connector has high levels of noise immunity with a range of 20~40 MHz. It meets requirements for electromagnetic compatibility (EMC) as per EN 60950. The connector meets the IEC standards of E61953-2 and the UL specifications of 94V0.
Conclusion
MDM-31PSR-A174 connector is designed for use in applications demanding low currents and good contact protection. It has wide range of applications in medical, automotive, industrial electronics, military, transport, computers and telecommunication. The connector is designed with two metal contact pins for reliable signal transmission across high speed and low-noise environments. It is also self-shielded and RoHS compliant, making it an ideal choice for applications requiring data acquisition and control. It is UL-approved and meets the requirements for EMC as per the IEC standards.
