YLCONNECTOR 4.5mm pitch / Disconnectable Crimp style Wire-to-wire connectors

Category: Connectors, Electronics, Jst Mfg Co Ltd

Overview

The datasheet primarily introduces the specifications and assembly details of YLCONNECTOR 4.5mm pitch, a series of disconnectable crimp style wire-to-wire connectors designed for varied electrical applications. The connectors are designed for a current rating of up to 10A AC or DC (2A with retainers mounted), a voltage rating of up to 300V AC or DC, and a temperature range from -25°C to +90°C. Initial contact resistance is specified at 7mΩ max, with a rise to 10mΩ max after environmental testing. Moreover, an insulation resistance of 1000MΩ min and a withstanding voltage of 1,500V AC for one minute are detailed, ensuring the connectors’ reliability and safety in use.

Electrical Specifications and Features

The connectors support wires ranging from AWG #26 to #16 or 0.13 to 1.25mm² and can be used with panels having a thickness from 0.7 to 2.0mm. It’s noted that the current rating of the connectors is subject to variation based on the number of circuits and wire sizes utilized. Another key feature is the introduction of the retainer for enhanced protection against improper insertion or disconnection. Details about the housing lance, inner-housing lock, and panel lock construction are included to provide guidance on usage and security.

Applicable Standards and Environmental Compliance

The datasheet states compliance with RoHS directives, ensuring the connectors abide by the latest environmental regulations. Additionally, JST (Japan Solderless Terminal) recognition and certification are cited, with designations E60389, LR20812, and R9351052, indicating the product meets the necessary quality and safety standards.

Physical Characteristics

Components such as the inner lock, retainer, and housing lance are depicted to elaborate on the physical attributes and functional aspects. However, it makes a special note that secondary retainers cannot be used with the largest wire gauge size (AWG #16).

Installation Guidelines

An important segment of the datasheet furnishes detailed panel layout and assembly layout instructions, inclusive of the model numbers of the connectors, corresponding circuit counts, and dimensions in mm. It provides guidance on the panel thickness compatibility per circuit housing and emphasizes that punch holes made in the panels for connector insertion should be free of any burrs. The user is also advised to consider the panel’s strength when creating multiple punch holes, and to ensure insertion is from the same side as the punched hole.

Connector Dimensions

Lastly, a table illustrates specific dimensions for connectors with varying numbers of circuits, clearly displaying the dimensional requirements to accommodate different configurations of connector assemblies, including those that involve retainers.
