1.0mm Dual Row Pin Header, Single/Dual Insulator, 180°

Pin Header Connector

Pin header, a type of connector, English name: Pin Header.

This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to serve as a bridge in places where the circuit is blocked or between isolated circuits that are not connected, undertaking the task of current or signal transmission. It is usually used together with female headers to form board-to-board connections; or used together with electronic wire harness terminals to form board-to-wire connections; it can also be used independently for board-to-board connections.

Because different products require different specifications, pin headers also come in many models and specifications. According to the standard classification of pin header connectors in the electronics industry:

By pitch, they can be roughly divided into five categories: 2.54mm, 2.00mm, 1.27mm, 1.00mm, and 0.8mm. By number of rows, there are single-row pin headers, double-row pin headers, triple-row pin headers, etc.; by packaging usage, there are SMT (horizontal mount/vertical mount), DIP (straight/right-angle), etc.; according to installation method: 180° is represented by S, 90° is represented by W, and SMT is represented by T.

Number of rows: single row, double row, triple row, quadruple row, with a maximum of four rows.

Number of pins: 02to80

Pins: straight pins, right-angle pins, SMT; pin size.

Dimensions: overall dimensions length, width, thickness, row spacing.

Pitch: 0.8, 1.0, 1.27, 2.0, 2.54 pitch.

Material: refers to contact material and surface treatment, insulator material.

Packaging: blister pack, reel bag, bulk pack.

Materials: pin material: brass or phosphor bronze; insulator material: plastic UL94V-0.

Surface treatment: gold plating 0.8u, tin plating, nickel plating.

Processing technology: The pin header processing technology process is mainly: first process the pins with brass (or phosphor bronze) as required,

and first nickel plate and then gold plate as required, then use a mold to process the insulator part, and finally on special equipment according to the size

requirements insert the pins into the insulator.

Note: There are many factors affecting the price, and the most influential are usually gold plating, pin length, etc. [1]

The rectangular pin cross-section is 0.8×1.6mm, and the load current is 7.5A. The socket has at least two independent spring pieces and four contact points, and the socket structure can prevent incorrect insertion. The 254/I series square pin cross-section is 0.64×0.64mm. The above two types of pins adopt a blunt-edge corner design and can be applied in high-frequency technology fields. The contact part of the pin hole is gold-plated, providing corrosion resistance, low contact resistance, and high reliability. [2]
