ITT Cannon Trinity MKJ series miniature circular connectors

ITT Cannon has released the Trinity MKJ family of miniature circular connectors, which are claimed to provide approximate electrical and mechanical characteristics of larger and heavier Military Standard Environmental connectors while reducing weight up to 71% and size up to 52%.

All the connectors’ shells and jam nuts are available in high-quality aluminium alloy or corrosion-resistant steel per AMS-QQ-S 763. The connectors come with rear accessory thread or integral band platform for direct attachment of cable shield and overmould. In addition, a Pogo Pin technology that uses ITT’s spring probe pin/touch pad contact system is available.

The MKJ series receptacle comes with a variety of mounting options for both crimp and PCB contacts including inline, jam nut, front mount, square flange mount and flange mount.

The MKJ0, MKJ1 and MKJ3 have a master key and two secondary keys for positive mating with four clocking positions available. The MKJ0 connector is suitable for everyday operations where size and weight are at a premium.

The MKJ1 connector is suitable for harsh shock and vibration environments. The MKJ3 connector can be fully mated in a ¼ turn. The MKJ4 connector provides a quick push-to-mate/pull-to-unmate disconnect mechanism for fast breakaway connections.

The MKJ series of products uses size 23 pin and socket contacts with equivalent electrical performance of size 22 contacts. These smaller contacts accept #22 to #28 AWG wire and allow the contact spacing to be reduced down to 1.93 mm.

The connector’s LCP dielectric insulating material can accommodate from 3 to 85 contacts in various shell sizes. This high-density packaging, along with a reduced wall thickness and scoop, allows a decrease in size and weight while retaining the approximate mechanical and electrical characteristics of heavier and larger Military Standard Environmental connectors.

The connector is capable of operating between -55 and +150°C and can be mated up to 2000 cycles. Maximum electrical current is 5 A and maximum voltage at sea level is 500 VAC RMS.
