D-Sub connectors are ubiquitous with many applications, from consumer electronics and home appliances to computers and industrial machines. The type of D-Sub connector being discussed in this article is the DM53742-5126 model which is a 15-pin or 9-pin male D-subminiature connector. The DM53742-5126 connectors are designed for reliable and high-performance data transmission in both isolated and non-isolated applications.The DM53742-5126 has a D-shaped body with 9 or 15 pins arranged in an asymmetrical pattern. It employs a locking mechanism to ensure secure mating and the 9-pin connector has an interlocking design while the 15-pin connector has an insert locking mechanism. The interlocking design ensures a mate-resistant connection, while the insert locking mechanism prevents disconnection when the head of the corresponding mating plug is inserted. The connector has a 50% pre-load to ensure that contact pressure is maintained between the mating connector and the contact pins.The DM53742-5126 model also uses four (for the 9-pin version) or five (for the 15-pin version) contact rails which firmly hold the contact pins. Furthermore, the contact rails and contact pins are secured within the connector body by a silicone O-ring which provides an extra layer of protection and improves the electrical and EMI/EMC characteristics of the connection.The DM53742-5126 male D-sub connectors are suitable for applications that require a reliable connection and high-speed, low-noise data transmission. It is compatible with a wide variety of cable types including: multi-bus cables, flat cables, and shield cables. The connector is available in both through-hole and surface-mount versions, making it suitable for a variety of applications.The DM53742-5126 is suitable for a range of applications including industrial and medical equipment, gaming systems, and transportation systems. The connector is rated for 10,000 mating cycles and the contact parts are nickel-plated for corrosion resistance. The 9-pin version is also available in cable-mount and PCB-mount versions for easy installation.In addition, the contact buttons on the DM53742-5126 are compliant with the UL758 and UL3257 specifications. They have a maximum current rating of 0.5A per conductor and a relative humidity rating of 90%. Furthermore, the connectors have a voltage drop of <1V for high-speed transmission and a resistance of < 10mΩ for low-noise transmission.In conclusion, the DM53742-5126 male D-subminiature connector is a reliable, high-speed, low-noise D-shaped connector that is suitable for a variety of applications. The connector is available in 9-pin and 15-pin versions and is rated for 10,000 mating cycles. It has four or five contact rails, a 50% pre-load, and a silicone O-ring for EMI/EMC protection. The contact buttons are compliant with UL758 and UL3257 specifications and the connectors are available in both through-hole and surface-mount versions.
