Rectangular Connectors - Headers, Male Pins - 3-1734493-2

3-1734493-2 rectangular connectors are useful for high-density board-to-board, cable-to-board, cable-to-cable and chassis-to-cable applications. A genderless header and receptacle combination come in 2 or 3-row versions with 0.5, 1.0, 1.5 and 2mm pin spacing. Whether you need to mate your interface or add external signals, 3-1734493-2 offers different versions to choose from.

Application Field

3-1734493-2 connectors are perfect for 1mm pitch, high-density board-to-board applications in telecom equipment, audio/visual equipment, and personal computers. Receptacle connectors provide the highest mechanical retention, longest insertion and extraction life cycles, and have a high resistance to water and dust.

Medical devices can also benefit from 3-1734493-2 header connectors, as they enable highly reliable connections with a high number of mating cycles. Headers with a lance terminal (also known as a terminal trap) allow for “shorting out” the contact pins during handling, preventing ESD damage. Whether you are connecting boards directly or mating wires through back panels, 3-1734493-2 connectors offer the reliable connections and secure mating required for medical applications.

With their secure latch design, 3-1734493-2 connectors can also be used in down-hole instrumentation applications. Their robust design ensures that electrical connections remain secure even in difficult environments.

Working Principle

The design and construction of 3-1734493-2 headers and receptacles feature standards that meet customer and commercial requirements for performance, economy, and durability. The anti-vibration design of the housing has a cross-breaking system that utilizes two independent mechanisms to prevent the housing from breaking open under heavy vibration.

The header’s contact pins are made of phosphor bronze and have 0.5, 1.0, 1.5 and 2mm pin spacing, depending on the series you need. Each pin is press-fit into the header body and soldered onto a circuit board. The receptacle contacts are made of phosphor bronze alloy and each contact is coated with an anti-corrosive finish to ensure long-term stability. The contacts also have a self-clinching feature that facilitates termination to PC boards.

The latch design of 3-1734493-2 connectors ensures that the housing is securely locked in place during connection. The latch comprises a lever arm and a locking pawl that ensure secure mating and unmating cycles. This latch design prevents accidental disengagement, providing dependable, secure connections.
