When inserting the battery pack the connector gets engaged by means of the battery terminals. Equipped with spring-loaded contacts the connector features a steady low contact resistance.


  • Housing: Sealed to IP67 (dust tight and protected against the effects of immersion) even when unmated or protected to IP23 without sealing
  • Spring-loaded contacts: Very low contact resistance, hohe high vibration and shock resistance
  • Customized versions: Various versions available concerning contact travel, contact arrangement, etc.


  • Telecommunications: Military, measurement and communications engineering, e.g. Light Field Radio (LFR), Multi Role Radio (MRR), police radio sets
  • Industrial electronics: industrial PC, portable systems for industrial purposes, e.g. industrial laptop
