ITT Cannon MKJ1 Connectors & CLIK Cordsets

Introduction

ITT Cannon MKJ1 connectors and CLIK cordsets are miniature circular interconnect solutions designed for demanding aerospace, defense, and other harsh-environment systems. They combine compact packaging with rugged environmental protection, reliable contact performance, and multiple termination choices.

Part Description

The MKJ1 product family consists of military-grade miniature circular connectors and compatible CLIK cordsets from ITT Cannon. These connectors use double-start ACME threads to support quick, secure coupling while helping maintain reliable mechanical retention in high-vibration applications.

MKJ1 connectors use size #23 contacts rated for a continuous current of 5 A. Available contact termination styles include crimp, solder-cup, and PC-tail options, allowing the connector to be integrated into wire harnesses, hand-wired assemblies, and printed circuit board designs.

Designed for harsh conditions, the family provides IP67 sealing against dust and temporary water immersion. It also offers resistance to shock and vibration and supports an operating temperature range of -65°C to +175°C. These characteristics make MKJ1 connectors suitable for compact systems where environmental durability and connection reliability are critical.
