Hirose Straight Surface PCB Socket, 4 Contacts, 1 Row, 2 mm Pitch, 12A, Board-to-Board/Wire-to-Board, Solder, Female DF59

The Hirose DF59-4S-2V(51) Straight Surface PCB Socket is an advanced board-to-board and wire-to-board connector designed to support demanding electrical applications. With 4 contacts in a single row and a fine 2 mm pitch, it provides a compact solution for edge and surface mounting of PCBs in industrial, lighting, and electronic systems.

This socket is engineered with a low profile mated height of 2.48 mm, making it ideal for designs where space constraints and shadow minimization are critical, including LED lighting modules and compact power electronics.

A robust swing lock mechanism combines both positive and friction locks, ensuring the header mating is secure against mechanical stress and cable pulls. The two-point contact design guarantees a reliable and consistent electrical connection while maintaining strong plug retention.

Supporting up to 12A current and 230V voltage, the DF59-4S-2V(51) socket is suitable for transmitting substantial power and signals across PCBs, enabling flexible integration in board-to-board and wire-to-board connector systems. The surface mount format simplifies automated production.

The housing is crafted from liquid crystal polymer, offering high durability, heat resistance, and dimensional stability under tough operating conditions. Brass contacts plated with gold optimize conductivity and protect against corrosion, delivering long-term performance.

Features a compact, PCB space-saving design for flexible layouts. Low profile mated height of 2.48 mm meets tight integration requirements. Secure swing lock mechanism prevents accidental unmating and ensures reliable mating.

Handles up to 12A and 230V for both signal and power connections. Wide temperature range from -40°C to 105°C for operation in diverse environments. Female contact gender, gold-plated brass for enhanced electrical performance.

Board-to-board and wire-to-board support increases design versatility.

This connector is primarily used in applications such as LED lighting arrays, battery connections, power supply modules, and small DC motor drives. The DF59 series also offers a ±0.5 mm floating function in XYZ directions, reducing thermal expansion stress and enabling multiple board-to-board connections with minimized component count.

The Hirose DF59-4S-2V(51) PCB socket is a preferred choice for engineers seeking high current capacity, compact footprint, and outstanding reliability in their electronics designs.
