2.54mm Pitch High Density Connector A1 and A2 Series Datasheet

Category: Connectors, Electronics, HIROSE Electric USA Inc

Overview

The datasheet provides information on the A1 and A2 Series High Density Connectors with a 2.54mm pitch, designed for space-efficient mounting and varied applications in electronic equipment such as computers and VTRs. The connectors are characterized by their high-density mounting capabilities, a wide range of contact variations, and compatibility with other series for diverse applications.

Key Features and Specifications

One of the main features of the A1 and A2 connector series is their high-density mounting configuration. The A1 series connectors can have 6 to 64 contacts, and the A2 series includes 20 different models with up to 20 contacts. The longitudinal alignment on a 2.54mm mesh board prevents idle space. The connectors are also compatible with the HIF3B series cable side and HIF3H receptacle, thereby ensuring versatility across various applications.

The electrical specifications highlight a current rating of 3A, with an operational temperature range of -55 to +85°C (Storage Temperature Range: -10 to +60 C) and a voltage rating of 200V AC. Additional specifications ensure robust performance, including an insulation resistance of 1000M ohms min, a withstanding voltage of 650V AC for 1 minute without flashover or breakdown, and a contact resistance of 15m ohms max. The connectors also boast a strong resistance to environmental factors such as vibration, humidity, temperature fluctuation, and soldering heat.

Material and Ordering Information

The insulators used in the connectors are made from PBT, with pin headers from Brass and crimping contacts from Phosphor bronze. Selective gold plating is applied to contacts for enhanced conductivity and corrosion resistance. A UL94V-0 rating signifies the material’s compliance with flammability standards. The ordering information provided outlines the coding system for series names, numbers, and contact counts, as well as pin header, crimping socket, and crimping contact options with different packaging types.

Applications

These high-density connectors are suitable for several types of electronic equipment, notably in the computing and video technology sectors.

Note on Conditions

Provided specifications cover not only operational conditions but also non-conducting states during storage, shipping, or transport, ensuring product maintenance over long periods before actual use.
