JST 2.0mm Disconnectable Crimp Style Connectors

Category: Connectors, Electronics, Jst Mfg Co Ltd

Overview

The JST 2.0mm Disconnectable Crimp Style Connectors are designed for secure and reliable connections in various applications. They feature a 0.079″ pitch and are equipped with multiple mechanisms to ensure stability and continuity.

Key Features

A fundamental aspect of these connectors is their locking device, which is integrated into the housing. This feature plays a crucial role in preventing accidental disconnections that could potentially be caused by external forces such as the movement of wires during assembly or due to vibrations.

Ensuring reliable contacts is paramount, and the contacts in these connectors are designed with long dimples near the center. This design guarantees the maintenance of low voltage and low current circuit continuity, which remains robust across various conditions, including vibration and forceful separation attempts.

An insertion guide mechanism is incorporated into the header for effortless and firm housing insertion. Additionally, the top entry type headers can come with a polarizing boss to prevent mismating, and the availability of dual-row construction enables high-density mounting options.

Specifications

The connectors come with an impressive current rating of 3A AC or DC for wires sized AWG#22, and the voltage rating stands at 250V AC or DC. Moreover, they can operate within a temperature range of -25°C to +85°C, which includes the temperature rise when an electrical current is applied.

The contact resistance is specified as initially 10mΩ max, and it goes up to 20mΩ max after environmental testing. As for the insulation resistance, it is above 1000MΩ at the initial measurement. The connectors can also withstand voltages up to 800V AC for one minute.

These connectors are compatible with wires ranging from AWG #28 to #22 and can be mounted on PC boards with a thickness of 0.063 inches (6mm). It is also noted that customers should contact JST if a Lead-Free product is desired, and instructions are available at the end of the catalog under the section “General Instruction and Notice when using Terminals and Connectors.” For further details, contact JST.

Certifications

The JST 2.0mm Disconnectable Crimp Style Connectors are FU Recognized under E60389 and also certified under LR20812, ensuring compliance with relevant industry standards.
