Compact, versatile wire-to-board connectors suited to high-vibration environments

October 2, 2025

Issue 7 2025

The Hirose KW30 series 100 V connectors feature a robust construction with contacts which offer high mechanical stability. Design features ensure correct mating and minimize the risk of damage to the receptacle when assembled.

The KW30 series wire-to-board connectors from Hirose have a robust construction which can withstand the strong vibrations experienced in harsh industrial environments. 

 

These connectors have been tested for tolerance of vibrations at frequencies up to 2,000 Hz. The rib design of the connectors ensures secure mating, while a two-point contact and clipping design on the receptacle, and a box-shaped plug crimp contact which resists catching or deformation, help to ensure excellent contact stability.  

 

The positive locks on the KW30 series prevent incomplete mating, mis-insertion and receptacle damage. When mated correctly, there is a clear tactile click. The connector also offers enhanced signal performance and contact durability thanks to its gold plated contacts. 

 

The KW30 series comes in a compact package featuring a contact pitch of 1 mm as standard, or 2 mm for the two-position version. The connectors are available in straight and right-angle configurations, and accept cables ranging in size from 28 to 32 AWG.
