KEL Corporation Introduces the FG Series Drawer Connectors

KEL Corporation, headquartered in Tama City, Tokyo, under the leadership of President Akira Kasuga, has officially launched its latest innovation: the FG Series, a range of 50A drawer connectors ideal for high-current applications. This new product caters specifically to the needs of connecting equipment batteries with the main units effectively and safely.

Overview of the FG Series Connectors

The FG Series connectors boast several advanced features designed for optimum performance:

• - Each power terminal can handle a maximum current of 50A, ensuring reliability for high-voltage applications.
• - By integrating two power terminals and six signal terminals into a single connector, KEL has successfully minimized the space requirement without sacrificing functionality.
• - A multi-point contact structure prevents buckling of the contacts, leading to increased reliability through stable contact force. Specifically, the power terminals have eight contact points, while signal terminals have two.
• - The connectors are equipped with a guiding mechanism that accommodates insertion errors by as much as ±3.5mm in the X direction and ±2.8mm in the Y direction, resulting in enhanced user experience during installation.
• - The design includes movable screw sections on the plug connector side, which allows for absorption in the XY directions of up to ±0.7mm, helping to facilitate easier connections.
• - Both the power terminal and signal terminal have effective mating lengths of 3.0mm and 2.4mm respectively, contributing to a high-reliability design that mitigates timing-related contact issues.

Detailed Specifications

FG01: Receptacle (Cable Side Connector)

• - Insulator Material: PBT (glass fiber reinforced) UL94V-0 Black
• - Contact Material: Copper alloy
• - Contact Finish: Nickel-plated base. Signal contacts feature gold plating at the contact area and nickel plating at the crimp area, while power contacts have gold plating at the solder area as well.

FG11: Plug (Cable Interconnection Connector)

• - Insulator Material: PA9T (glass fiber reinforced) UL94V-0 Black
• - Contact Material: Brass
• - Contact Finish: Nickel-plated base similar to FG01. Signal contacts are gold-plated and feature tin-plated tails, while power contacts have gold plating at the contact area and tin plating for soldering.

Performance Ratings

• - Rated Current: Signal contacts can handle 3.0A/1PIN (AWG#18/20) while power contacts are rated for 50A/1PIN (AWG#6) and 40A/1PIN (AWG#8).
• - Contact Resistance: Signal contacts have less than 10mΩ, while power contacts have less than 3mΩ.
• - Withstand Voltage: Signal contacts can endure AC1000V for 1 minute, and power contacts withstand AC2000V for 1 minute.
• - Insulation Resistance: Measured at DC500V, achieving above 1000MΩ.
• - Insertion and Removal Durability: Rated for 500 cycles.
• - Operating Temperature Range: Functionality maintained from -55℃ to +105℃.
• - Compatible Cables: Signal contacts can work with AWG#18/20 (cable outer diameter: Φ1.8~2.8mm), and power contacts are compatible with AWG#6/8.

Application Areas

These connectors are particularly suitable for various industrial markets, including:

• - Uninterruptible Power Supplies (UPS)
• - Lighting systems
• - Agricultural machinery
• - Construction equipment
• - Drones
