EP CONNECTOR SERIES
Interface type
Emboss Tape
3.5EP Type R
• 3.5mm in diameter. Connector for 4-circuit plug
(EIAJ RC-5325A-compliant plug)
• Normal close, Independent switch
The plug with different GND position is also
available by adopting the plug and the block
electricity switch function.
• Round shape
This connector shape is available for round
shape of adoption chassis.
• Adopting two contact points terminal
2 contact points terminal for the GND/MIC
terminal is adopted to reduce the electrical
resistance.
3.5EP SLANT3 Type
• 3.5mm in diameter. Connector for 4-circuit plug
(EIAJ RC-5325A-compliant plug)
• Normal close, Independent switch
The plug with different GND position is also
available by adopting the plug and the block
electricity switch function.
• Insertion and withdrawal forces of plug
Lock pin is adopted to improve insertion force
feeling and to strengthen withdrawal force of
plug.
• Biotechnology resin
Resin produced by partially using the plant-
based raw material for the housing material is
adopted.
