It focuses on miniaturization and high density, with a pin pitch of only 0.80mm. It fits ultra-compact spaces like smartphones and smart wearables, often used with FPC cables to enable low-power signal transmission between the mainboard and miniature modules, meeting the lightweight needs of consumer electronics.

With high-precision connection as its core advantage, the pin pitch is precisely controlled at 1.00mm. It adopts an LCP high-temperature-resistant shell, suitable for devices with high requirements for signal stability such as UAV flight control boards and small medical detectors. It supports high-frequency and low-loss transmission to avoid data interference.

As a representative of general-purpose miniature specifications, it has a pin pitch of 1.27mm, balancing density and ease of operation. It is widely used in router modules, digital camera motherboards, and small PLC devices. It can be flexibly matched with single/double-row designs to meet the demand for synchronous transmission of multi-channel signals and low-voltage power supplies.

It belongs to the combined pitch specification, with a staggered pin layout of 1.27mm horizontally and 2.54mm vertically. It can expand connection channels in limited space, is suitable for industrial sensor modules and composite interfaces of test fixtures, supports mixed connection of board-to-board and board-to-wire, and improves interface utilization.

Focusing on medium-density industrial adaptation, it has a pin pitch of 2.00mm. Most shells are equipped with foolproof protrusions to prevent reverse insertion during automated assembly. It is commonly used in automotive electronic sub-control boards and smart home central control modules, with a temperature resistance range of -40℃~85℃, meeting the usage requirements in mild industrial environments.

It is the most universal standard specification, with a pin pitch of 2.54mm. It features mature technology and low cost, suitable for computer hard drives, printer motherboards, Arduino development boards, etc. It supports through-hole/SMD mounting methods and is compatible with most standard pin headers and IDC cables on the market.

Focusing on industrial-grade strong stability, it has a pin pitch of 3.96mm. The pins are thick with a large contact area, suitable for high-power devices such as industrial frequency converters, motor control boxes, and photovoltaic combiner boxes. It can transmit large-current low-voltage signals, and the shell has a latch design to prevent detachment due to vibration.

It belongs to the large-pitch heavy-duty specification, with a pin pitch of 5.08mm. Mostly single-row through-hole type, it is suitable for distribution box terminals, power interfaces of large testing equipment, and electric tool control boards. It supports high-current transmission (usually over 5A), with large insertion force and reliable connection, suitable for frequent operation scenarios in industrial fields.
