172-E25-111-021

D-Sub connectors, or D-Subminiature connectors, are widely used in the electronics industries. They’re known for their excellent shielding performance, and they’re used in a variety of applications, from communication infrastructure to test and measurement equipment. The particular connector being discussed here is the 172-E25-111-021. It is a 25-pin connector with the option of either solder or pin headers, making it versatile enough for a variety of applications.

The 172-E25-111-021 has been specifically designed for use in applications such as data bus and communication protocols, as well as in applications requiring 10 Mbps data rates. The connector is capable of handling voltages up to 30V and current of up to 1.5A. The insulation resistance is also good, with a value of up to 500 M?@500V DC. It also has excellent EMC features, being able to shield against interference in the range of 0-400 MHz and up to 45 dB.

The connector also has good mechanical properties, with an operating temperature range of -55°C to +105°C. It has been designed to have good durability and reliability, and is able to withstand up to 500 mating cycles. The contact resistance is rated at less than 10m? and the contact retention force is rated at 10N.

The working principle of the 172-E25-111-021 is based on the principle of surface contact. The contact area consists of a female contact at one end and a male contact at the other. The two contacts are held together by a dielectric sleeve, and as they are pushed together, they are forced into contact with each other. This creates a reliable electrical connection. The contact area is also designed to provide a good mechanical connection, with a retention force of 10 N.

In conclusion, the 172-E25-111-021 is an excellent connector, ideal for situations where a reliable electrical connection is needed, such as in communication protocols and test and measurement equipment. It has excellent electrical and mechanical properties with good EMC characteristics, and is capable of withstanding up to 500 mating cycles. The working principle is based on the principle of surface contact, and the two contacts are held together by a dielectric sleeve.
