Locking/Unlocking and Insertion/Extraction tweezer to handle MHF® 4L LK

Hand Tools to operate locking/unlocking and insertion/extraction.

Unlocking, Extraction tweezer Narrow Pitch, Locking/Unlocking, Extraction tweezer
MHF_I_LK_Extraction_Tweezer

Unlock the lock and remove it while holding the plug.

 MHF_I_LK_Extraction_Narrow_Pitch

The narrow-pitch design enables unlocking as well as insertion and removal, making it suitable for work in confined spaces.

 

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.
