Hirose DF40 Series Straight Surface PCB Header, 100 Contacts, 0.4 mm Pitch, 2 Row, Shrouded DF40

Hirose DF40 Series Straight Surface PCB Header, model DF40, provides a robust and high-density solution for board-to-board and board-to-FPC connections in electronic components. This connector features 100 contacts arranged in 2 rows with a fine 0.4 mm pitch, enabling compact and efficient circuit design.

The connector's housing is made from Liquid Crystal Polymer, which offers excellent durability and resistance to environmental factors. The contacts are manufactured from copper alloy with gold plating to ensure superior electrical conductivity and corrosion resistance.

This surface mount PCB header includes a shrouded design that protects delicate contacts from contamination and prevents electrical shorting. A locking mechanism with an audible click ensures reliable connections and prevents accidental disconnections during operation. Guide ribs assist in precise alignment by allowing a 0.33 mm self-alignment during mating, which improves assembly efficiency.

The DF40 connector has a reinforced structure enhanced by shock absorbing ribs, designed to withstand mechanical stresses such as impact and vibration, making it suitable for demanding industrial and commercial electronic applications. It operates reliably within a temperature range of -35°C to 85°C and supports a voltage rating of 30 V and a current rating of 300 mA.

High density design supporting 100 contacts at 0.4 mm pitch. Shrouded housing protects contacts from dust and debris. Constructed with Liquid Crystal Polymer housing and gold plated copper alloy contacts. Supports surface mount for board-to-board and board-to-FPC systems.

Locking mechanism with audible click ensures mating assurance and prevents accidental unmating. Guide ribs enable self-alignment with 0.33 mm tolerance during mating. Reinforced structure includes shock absorbing ribs to protect against vibration and impact.
