Product Details

Engineering Features	Technical Advantages	Customer Benefits
High Power-to-Size Ratio	Rated for 10.5A and 600V within a compact 3.81mm pitch footprint.	Optimize System Layout: Allows for significant space savings on the PCB/Panel without sacrificing power delivery, perfect for miniaturized industrial controllers.
Advanced KY Keying Design	Features unique mechanical alignment slots specifically for the KY configuration.	Eliminate Installation Errors: Ensures that only matching headers can be connected, preventing catastrophic electrical damage caused by incorrect cross-mating in complex wiring.
Robust Locking Mechanism	Integrated secure latch that provides a definitive tactile “click” during mating.	Zero Maintenance Downtime: Prevents accidental disconnection under high-vibration environments (e.g., CNC machines, robotics), ensuring constant signal and power integrity.
Wide Gauge Compatibility	Supports a versatile wire range from 28 AWG for signals to 14 AWG for power.	Inventory Cost Reduction: Standardize your connector stock across different departments by using one series for both signal and medium-power applications.

Q1: What terminals are required for the F32FSS-05V-KY housing?

A: This housing is compatible with JST JFA-J300 series crimp contacts. You should select terminals based on your wire gauge (AWG 14-28). Common models include the SF3F-71GF-P2.0 (gold-plated) for optimal conductivity and corrosion resistance.

Q2: What is the significance of the “KY” suffix?

A: The “KY” suffix indicates a specific Keying Type. JST J300 series connectors often come in multiple keying options (A, B, C, etc.) to allow multiple connectors of the same size to be used on one board without the risk of plugging them into the wrong header.

Q3: Can I use this connector for 220V AC industrial applications?

A: Yes, absolutely. With a rating of 600V AC/DC, the F32FSS-05V-KY is well-equipped for standard 220V/380V industrial power systems, provided the current draw does not exceed 10.5A per contact.
