Hirose Miniature Waterproof Plastic Connectors

HR30 Series*

Hirose Electric HR30 Miniature Waterproof Plastic Connectors are rated IP67 for complete protection against dust and water penetration when submerged one meter deep for half hour. The HR30 connectors are short in length when fully terminated and mated and feature a built-in lock/release mechanism that securely locks the mated connectors while allowing a quick disconnect by simply pulling on the plug 's release collar. The Hirose Electric HR30 Miniature Waterproof Plastic Connectors are user friendly with molded-in grooves to prevent hand slippage, permanent colored alignment indicators, and multiple polarizing keys to protect from misalignment or insertion of the wrong connector.

HR30 Features
  • Small size - Short in length when fully terminated and mated.
  • Water and dust protected - IP67 protection rating: Complete protection against dust penetration and against water penetration when submerged 1 meter deep for half hour. Mated with corresponding connector or protective cap.
  • Simple pull lock release - Built-in lock/release mechanism securely locks mated connectors while allowing quick disconnection by simply pulling on the plug ’s release collar. Molded-in grooves prevent hand slippage when pulled. The round configuration of the collar allows easy side-by-side panel mounting and will not snag on objects when the cable is pulled-out.
  • Light weight, corrosion resistant - Glass reinforced thermoplastic compounds and noncorrosive components are used in all assemblies.
  • Contact protection and self-alignment - Multiple polarizing keys protect the contacts from mis-alignment or attempted insertion of the wrong connector , while assuring correct mating between the corresponding connectors.
  • Visual alignment indicators - Permanent alignment indicators in a contrasting color on all connectors aid in correct alignment and engagement.
  • Built-in cable strain relief

HR30 Applications

Test and measuring equipment, portable devices, instrumentation, industrial devices, recreational equipment, I/O applications and other applications requiring use of lightweight, corrosion resistant quick mate/ release cable connections.
