Standard type
Features ––––––––––––––––––––––––
• Stackable
This connector is stackable in both directions.
• Low profile
This connector measures 8.5mm high after mounting. The
receptacle is 6.0mm high.
Grooved type
• High reliability
Each contact makes an electrical connection with its mating
header post at two points. This redundancy ensures continuity
even under adverse environmental conditions.
• Through style
The receptacle allows the mating post to pass completely
through and measures 6.0mm in height. It is suited for various
headers having posts measuring 6.0mm or more in height.
• Provides convenient test points
This is a two-circuit jumper connector
suited for changing or switching circuits
on printed circuit boards without using
DIP switches. It is compact and light, thus
can be mounted on printed circuit boards
without interfering with the placement of
other components. The connector is easy
to use, low in cost, and has a wide range
of applications in industrial and consumer
products.
Standard type
Grooved type
Provides extra test points where circuits can be checked without
the disassembly of components.
