Insertion/Extraction tools to handle MHF® I (4 pads receptacle)
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.
Adapters for plugs and receptacles
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. |
SI Test boards for signal integrity performance measurement
Signal Integrity testing, measures and analyzes the extent to which high-speed signals maintain their integrity when transmitted through a connector.
