JST ACHF Series Connectors, Custom Wire Harness
JST ACHF Connector Introduction
Many applications in various industries, such as consumer electronics, automotive, and telecommunications, require wire-to-board connectors that are not only sub-miniature in size but also offer engineers design flexibility. The ACHF series wire-to-board connectors perfectly meet these requirements.
These connectors have a pitch of 1.2mm (.047”), which allows for compact designs without compromising performance. Molded from a 94V0 heat-resistant material in black color, they can withstand high temperatures and ensure reliable operation even in demanding environments.
One notable feature of the ACHF series is their surface mount technology (SMT) compatibility. This means that they can be easily mounted onto printed circuit boards using automated assembly processes, saving time and effort during production.
Additionally, these connectors are polarized to prevent incorrect mating and ensure proper electrical connections. They also come with a secure friction locking feature that provides added stability once connected.
Another advantage of the ACHF series is their low profile design with a height of only 1.43mm (.056”). This slim profile allows for space-saving installations while maintaining excellent electrical performance.
Furthermore, these wire-to-board connectors are designed as a top entry but side-feed type, making them suitable for various power supply applications. With a power supply circuit rating of 2.5A and a signal circuit rating of 1.0A, they can handle both high-power and low-power signals effectively.
The ACHF series wire-to-board connectors offer engineers an ideal solution when it comes to sub-miniature size requirements combined with design flexibility. Their compact size, heat resistance capabilities, SMT compatibility, polarization feature, and secure friction locking make them highly versatile for use across different industries where reliable electrical connections are crucial.
