MTMM-120-03-S-D-150 connectors are a type of rectangular connectors known as headers with male pins. It is commonly used in many industries such as consumer electronics, automotive, medical, military and aerospace, and automation control systems. It has an operating temperature range of -55C to +125C and is suitable for applications where low pressure and moisture are concerned.

The body of the MTMM-120-03-S-D-150 headers houses a metal, stamped male pin insert consisting of a single row of 120 pins. The pins are spaced 3mm apart with a total board height of 150mm. They provide the electrical connection between the board and the component and feature a low-stress contact spring. The contacts are plated with either tin in the pin area, or gold in the tail area. The housing is made up of a strong thermoplastic, typically either UL94V-0 or UL94V-2 rated material, and provides the required protection from possible environmental damage.

The MTMM-120-03-S-D-150 connectors are suitable for both through-hole and surface mount applications. For through-hole operations, the pins are inserted as a unit into the bore holes of the circuit board and held in place by an interference fit. For surface mount applications, the pins are pre-mounted onto the circuit board and held in place by moderately high pressure. The panel-mounted version also uses a single row of pins, but these pins are pre-assembled and mounted on the side of the connector housing that faces the panel.

In terms of operation, the MTMM-120-03-S-D-150 connectors are designed to contact with the board\'s microvias and establish an electrical connection. The signal pins of the connector are then soldered to the board with a soldering iron. The pins are then pressed into contact with the connector slightly, providing a secure connection. The other contacts of the connector are then pressed into contact with the pads of the board either by hand or with a vacuum tool.

The MTMM-120-03-S-D-150 connectors feature a guide pin, which ensures that the contacts are engaged in the correct place with the right amount of pressure and make the right electrical contact when mating. The pins also have a tapered contact tip which provides a highly reliable contact interface when mating with the board. The pins also feature a switchable locking mechanism which ensures that the contact stays securely and accurately in place.

Overall, MTMM-120-03-S-D-150 connectors are a reliable, robust and compact solution for many applications. They provide a secure electrical connection between circuits with minimal risk of breakdown or short circuits. The locking mechanism ensures that the pins remain in contact even under high vibration and shock and they are also suitable for use in high-frequency applications.
