95278-401A20 rectangular connectors, headers, and male pins are designed to provide quick and easy electrical connections between multiple components or wires. They are used in a wide range of applications, from industrial assembly to automotive, electrical, computer, communications, and consumer electronics.

Product Overview

95278-401A20 headers are compact 1.08 inch-wide rectangular components that feature two rows of staggered gold-plated contact terminals with 20 positions (10 per row). The 1.4-mm pitch includes a locking latch pin to ensure secure mating. The lock pin also prevents accidental unmating. The headers are available in either surface-mount or through-hole configurations, and are compatible with the AMPMODU Mod II™ system.

The connectors are designed for a maximum 11-amp system current. The contact plating is RoHS-compliant matte tin over nickel. The headers are shielded with an anti-EMI housing to minimize interference. They are UL 94V-0-certified, UL-recognized (E482253), and CSA-certified (LR111717). The operating temperatures range from -55 to +105°C (with a 30-minute peak of +110°C).

Application Field and Working Principle

95278-401A20 rectangular connectors are well-suited for a multitude of applications, such as assembly, automotive, circular, medical, office, and telecom applications. The connectors are also well-suited for ground and board-to-board applications. The headers provide reliable connections when mating to PC boards, cables, and other components. They also enable easier installation of a few components or many components during assembly.

The connector’s design includes a faraday cage effect, which helps minimize electromagnetic interference (EMI). The two rows of contact terminals are staggered, which increases the spacing and allows for a more secure connection. The gold contacts reduce wear and allow for higher speed and repeat data transmission.

The locking latch pin on the male pins help ensure that the two connectors remain securely connected. The pin also prevents accidental unmating. The latch pin is equipped with a secure release mechanism to ensure quick and safe connection and disconnection. The connector’s design also allows for easy cleaning and maintenance. The headers’ RoHS-compliant matte tin over nickel plating provides good electrical contact and corrosion resistance.

Advantages

95278-401A20 rectangular connectors, headers, and male pins offer many benefits. They are reliable and secure, and the pin spacing increases contact stability. The gold contacts reduce wear and provide higher speeds and repeat data transmission. The faraday cage effect minimizes EMI, which ensures that electrical signals remain clean and interference-free. The connectors are UL, CSA, and RoHS-compliant and are rated for up to 11-amp systems.

The headers also feature easy installation and maintenance. They can be safely mounted to board assembled or preassembled. The locking latch pin helps ensure secure connection, and the pin also prevents accidental unmating. Additionally, the connector’s RoHS-compliant matte tin over nickel plating provides good electrical contact and corrosion resistance.
