R35K Board-to-FPC connector

Small, robust and powerful: New R35K single row connectors up to 3A with 49% space reduction.

Single row terminal for 49% mounting space reduction

Wearable devices has to be as small as possible. When it comes to connectors for batteries, side switches or various sensor modules, R35K series benefits from its single side terminal structure. Result is an incomparable easy wiring that saves up to 49% PCB space. Even in this small size R35K adapts the unique TOUGH CONTACT technology for highest device reliability.

Key features

  • 4 pins and 6 pins
  • Low profile, 0.6mm mated height
  • Power terminal 3A / pin contact
  • Signal terminal 0.3A / pin contact
  • 30V AC/DC
  • Double contact with a simple lock structure
  • High shock & vibration resistance

How to reduce board mounting area?

Downsizing while increasing performance at the same time is a key success factor for wearables, hearables and other smart devices. Compared to conventional connectors wit a double row structure, R35K series offers a space saving single row structure that enables wiring from one side. This saves up to 49% space and simplifies the routing on the PCB.
