2.5mm Pitch Board to Board Vertical Post Header
MDF14A Series
sFeatures
1. Service Efficiency Up contact and contact.
The post header is developed in the special design capable
of vertically connecting the board unnecessary for insertion
or extraction.
The post header can be connected in combination of the
receptacle with the plug at low cost.
2. Current Capacity [5A]
By adopting the 0.8mm round pin as the post pin, the pin
strength can be enhanced as well as the current capacity
can be maintained at 5A approximately.
3. Board Pre-fixed Mechanism
The kink process is provided for the board pre-fix process.
4. Pin Extraction Specification
The post header corresponds to individual pin extraction
specifications.
