How to Select the Right Pin Header Connector

Pin Header:The Essential Bridge in Electronics
Apin header connector,commonly known as apin header,is a fundamental component in modern electronics.It consists of a series of rigid metal pins arranged in single or double rows within an insulating plastic base,designed to mate with a socket Connector.

Key Selection Criteria for Pin Headers:
Pitch:Critical to match the mating connector's pitch,with common standards including1.27mm pin header,2.0mm Pin Header,2.54mm Pin Header,and5.08mm pin header.
Current/Voltage Rating:Determined by pin size and material.
Mounting Style:Choice between through-hole or surface-mount(SMT).
Mechanical&Environmental Needs:Consider locking features,polarization,and material specifications for harsh conditions.
