YLCONNECTOR 4.5mm Pitch Crimp Style Wire-to-Wire Connectors Datasheet

Category: Connectors, Electronics, Jst Mfg Co Ltd

Overview of YLCONNECTOR Wire-to-Wire Connectors

The YLCONNECTOR series features disconnectable 4.5mm pitch wire-to-wire crimp style connectors. With a maximum current rating of 10A AC/DC (2A when retainers are mounted) and voltage rating of 300V AC/DC, these connectors are designed to perform in a wide temperature range from -25°C to +90°C. The datasheet outlines specifications including a maximum initial contact resistance of 7mΩ, a maximum contact resistance of 10mΩ after environmental testing, and an insulation resistance of 1,000MΩ minimum. High durability is ensured with a withstanding voltage of 1,500V AC for one minute.

Applications and Compatibility

YLCONNECTOR is applicable for a wire range of AWG #26 to #16 (0.13mm² to 1.25mm²) and panel thicknesses from 0.7mm to 2.0mm. Additionally, the connectors meet RoHS compliance for reduced environmental impact. An informative note cautions that current ratings vary depending on the circuit count and wire size used.

Retention and Locking Features

The connectors are enhanced with retainers for extra protection against non-insertion or disconnection incidents. Other features include an inner-housing lock and housing lance for secure assembly. A secondary retainer option is available but cannot be used with the largest wire gauge (AWG #16).

Certifications and Standards

YLCONNECTOR connectors adhere to recognized standards, including E60389 and certifications such as LR20812 and R9351052, ensuring they meet industry quality and safety benchmarks.

Panel Layout and Connector Dimensions

Information for Panel Layout supports proper installation with detailed model numbers, dimensions, and recommended panel hole punching guides. Subsequent notes recommend burr removal for clean assembly and consideration of panel strength when creating multiple holes.

Contact and Material Specifications

Contact points are made from phosphor bronze with tin-plating subjected to reflow treatment. Various models of pin and socket contacts are detailed with their applicable wire sizes, insulation outer diameters, quantity per reel, and associated crimping equipment. Furthermore, specific product notes highlight the need to consult JST for special product requests and limitations on retainer usage with certain wire sizes and insulation diameters.

Connector Components and Positioning

The datasheet describes the design with contact position location numbers imprinted for accuracy in assembly. Both receptacle and plug housings are broken down, highlighting compatibility and application ease.

Note: All referenced features, specifications, and compatibility details are summarized directly from the first two pages of the datasheet for YLCONNECTOR 4.5mm pitch wire-to-wire crimp style connectors.
