D-Sub connectors are a kind of electrical connector widely used in electronics, computing, and telecommunications equipment. The DDMZ-47X1S-N-A197 is one of these connectors that has specific applications and a precise working principle.

The DDMZ-47X1S-N-A197 is a miniature connector, measuring 7.6x11.9mm, and is designed for straightforward installation and secure connection in a number of applications. Most common among these are in instrumentation and communication devices, being an ideal solution in cases where space is limited and high density connection sockets are needed. This is suitable for positions in small telecoms, portable electronic equipment, medical devices, audio-visual systems, and even computer and data communications.

These connectors’ rated current is 2.5A, voltage is 250VAC, and the insulated temperature is −25°C to 85°C. The shell is made of brass, gold plated, and has self-latching and blind mate features for reliable connection; the contact pins are designed out of high-performance copper alloy and are hollow for easy installation. They have a rated dielectric strength of >1000Vrms, a life span of up to 5000 mating cycles, and a contact resistance of <3mΩ.

The DDMZ-47X1S-N-A197 has a relatively straightforward working principle. This device consists of two plugging pieces that are interconnected with an array of pins. These pins fit in a keyed connector system that allow only compatible connections and prevent any damage to the devices. Furthermore, they have an auxiliary screw and latch design that securely fasten the two connectors together and used to prevent contacts from separating during the course of the connection.

When plugged in, the corresponding pins from the connectors come in direct contact; thus allowing the electrical current to pass through the device. The barrel of the connectors make contact due to the pressure generated by the lock. The auxiliary screw is tightened to prevent any misalignment between the connectors and ensure the current is flowing through the appropriate pins. Through this mechanism, DDMZ-47X1S-N-A197 guarantees a reliable connection in a number of instrumentation and communication applications where space is limited.
