Wire-to-board connectors are essential components for establishing reliable and efficient electrical connections between wires or cables and a printed circuit board (PCB) without the permanent nature of soldering. These connectors are designed to be disconnectable, allowing for easy assembly, maintenance, and replacement of components. The following outlines common JST wire-to-board connector types, providing a guide for understanding the variety and applications of these widely adopted solutions across industries including electronics and automotive.
The JST SUR connector is a compact, 0.8 mm pitch wire-to-board insulation displacement connector (IDC), notable as the world’s first of its kind. It features a low-profile design and high contact reliability, requiring no crimping. Commonly used in high-density electronics, it excels in applications like laptops, smartphones, and wearable devices, where space is limited. Its heat-resistant housing supports reflow soldering, making it ideal for automated PCB assembly in consumer electronics and miniature digital products.
The JST SH connector, the world’s first 1.0 mm pitch crimp-style wire-to-board connector, boasts a compact, low-profile design. Its housing lance system ensures smooth contact insertion with smaller wires, while the high-pressure contact design delivers reliable, assured connections. Rated for 1.0 A and 50 V, this space-saving connector excels in high-density applications like wearables, laptops, drones, and medical devices, offering excellent performance and dependability in compact electronics.
The JST ACH connector is designed for DC power supply, offering a compact and low-profile build. Its 1.2mm pitch and small size (1.4mm height, 4.3mm width) make it suitable for space-limited applications. It features a locking mechanism for secure connections. This makes it ideal for LED lamps and small electronic devices needing reliable power in tight spaces.
The JST GH connector is a 1.25 mm pitch, wire-to-board connector designed for high-density applications. Featuring a secure locking mechanism and low insertion force, it ensures reliable, easy mating. Its compact, low-profile design suits small electronics. It’s widely used in devices like LCDs, PDPs, notebooks, and drones, where space-saving and dependable connections are critical.
The JST GHD connector is a compact, double-row wire-to-board solution designed for high-density PCB mounting. Its small size and reliable locking mechanism make it ideal for space-constrained electronics. Commonly used in flat-panel TVs, AV equipment, and other consumer devices, it ensures secure connections despite its miniature footprint. The GHD’s ease of use and durability cater to automated assembly processes, making it a top choice for manufacturers seeking efficiency and performance in tight layouts.
The JST ZH connector is a compact, low-profile component widely used in consumer electronics, industrial controls, medical equipment, and hobbyist projects. Its small size suits space-limited applications, while its reliable design and compatibility boost its versatility. From household appliances to industrial automation, it supports critical electrical connections in numerous electronic products.
The JST ZPD connector is a wire-to-board solution tailored for high-density PCB designs, featuring a dual-row structure and a secure lock mechanism. It offers low insertion force and a smooth mating experience, ensuring dependable connections. With excellent resistance to prying during insertion and extraction, plus a suction area for automated assembly, it’s ideal for applications like wearables, medical devices, and industrial equipment needing reliable, compact connectivity.
The JST ZE connector, a 1.5 mm pitch wire-to-board solution, excels in high-density PCB designs with its solid locking feature. It offers low insertion force and a tactile click for easy, reliable mating. The secure lock and large outer design ensure confidence in connection and release, while the housing prevents mismating. Exceptionally simple to assemble, it’s ideal for applications like consumer electronics, automotive systems, and industrial controls.
The JST PH connector is a low-profile, wire-to-board solution with a space-saving design, boasting a mounting height of 8 mm and a slim 4.5 mm width in its top-entry form. Its boxed-shaped shrouded header ensures high reliability, making it ideal for high-density PCBs in compact electronic equipment. Offering excellent functionality for PCB mounting, it’s widely used in applications like consumer electronics and small devices. SMT headers are available from 2 to 16 positions.
The JST PUD connector, a 2.0 mm pitch, dual-row wire-to-board solution, features a robust locking mechanism for reliable contact under vibration and stress. Its design ensures low insertion force and high precision alignment between housing and header, simplifying board mounting. With high-reliability contacts, easy operation, and optional boss headers for polarization, it’s ideal for automotive systems, industrial controls, and consumer electronics needing secure, efficient connections.
The JST XH connector is a highly reliable, versatile wire-to-board solution with a 2.5 mm pitch and a low-profile assembled height of 9.8 mm, perfect for space-sensitive designs. It features an original double-leaf contact design for secure connections, a box-shaped shrouded header, and an optional boss variant. Commonly used in home automation systems, LED lighting, and small appliances, it ensures dependable performance.
The JST VH connector is a small, field-proven solution for printed circuit boards, offering reliability and a large current carrying capacity. Its versatile design supports a wide range of signal, power supply, and output circuits, making it a trusted choice in consumer electronics. Common applications include power supplies in appliances, industrial equipment, and automotive systems, where its robust performance excels.
However, JST does not offer an SMT version of the VH series. In contrast, LDZY Electronics provides both straight and right-angle SMT versions, expanding options for surface-mount applications.
The JST LEB connector, tailored for LED lighting, boasts a low-profile height of 2.7 mm, optimizing space in compact designs. It supports horizontal PCB connections, incorporating a misalignment absorption mechanism (pitch direction only) to handle parallel setups and thermal expansion. High-pressure fork-type contacts ensure stable performance despite PCB movement, while a prevention feature stops incorrect insertion. Compatible with crimp-type sockets, it shares PCB layouts with plug and receptacle types. Common applications include LED lighting systems, automotive displays, and compact electronics requiring reliable, space-saving connections
