Insertion/Extraction tools and tweezers are ready for MHF® 4L

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.

 

Insertion/Extraction tools

 How to extract

MHF 4L_Insertion/Extraction tool

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

 

Insertion/Extraction tweezers

 How to extract

Insertion/Extraction tweezer_1

Closing the tool lightly, slide it to the end.

 Insertion/Extraction tweezer_2

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

 

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)
MHF_I&_LK_Rece_Standard

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.

 MHF_I&_LK_Rece_High_Cycle_Standard

The Standard type connects directly from the probe to the measuring instrument.

 MHF_I&_LK_Rece_High_Cycle_Narrow

The Narrow pitch type is designed with a tight pitch, allowing multiple probes to be aligned and measured simultaneously.

 MHF_I&_LK_Rece_High_Cycle_Detachable

The Detachable type allows the adapter and probe to be removed and replaced. The base adapter is compatible with all series.

 

SI Test board 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.
