Inspection tools and SI test boards are essential for verifying that connectors are implemented as intended and perform as expected in actual applications. The use of dedicated insertion and extraction tools ensures secure operation and provides greater confidence during assembly and maintenance.

For plug inspection, Electrical Performance Check and Voltage/Continuity Check tools are provided.
Receptacle inspection tools, on the other hand, support Electrical performance check only.
The lineup includes various types to suit different applications, such as Standard series, High Cycle types with different durability ratings, and narrow-pitch types that enable operation on high-density PCB layouts.

Standard series	High Cycle Series
	Standard type	Narrow Pitch type	Detachable type
Durability: 500	Durability: 10,000	Durability: 10,000 (Probe), 100 (Cable)	Durability: 10,000 (Probe), 200,000 (Base)
Since the receptacle and the adapter are manually mated, the durability cycles are limited to 500. This type is best suited for inspection in small scale production environments, such as laboratories.	The Standard type connects directly from the probe to the measuring instrument.	The Narrow pitch type is designed with a tight pitch, allowing multiple probes to be aligned and measured simultaneously.	The Detachable type allows the adapter and probe to be removed and replaced. The base adapter is compatible with all series.

Signal Integrity testing, measures and analyzes the extent to which high-speed signals maintain their integrity when transmitted through a connector.

Due to the small size of the products and the need for appropriate connector mating, dedicated insertion and extraction tools help ensure safe operation and improve reliability during assembly and maintenance.

How to extract

Slide the tool until it reaches a stopper, lift vertically to the PCB surface.

How to extract

Closing the tool lightly, slide it to the end.

Clip the plug and pull the tool vertically from the receptacle to withdraw.
