www.ittcannon.com Dimensions shown in inches (mm) Specifications and dimensions subject to change BMini Circular The Challenge ITT has a long history of providing standard and custom MIL-DTL-38999 connectors which meet the most stringent military requirements. ITT’s major military and commercial accounts recently approached us requesting that we take our proven high reliabilty designs and shrink them to decrease weight and size while maintaining the connectors robust environmental performance and high reliability. Along with these requests, ICS received substantial commentary from other markets including Medical, Industrial, and Space, requesting a similar, miniature circular product. The ITT Solution … ITT took on the challenge, driving innovation in mating capabilities and contacts to reduce size and weight while maintaining the high level of quality customers have come to expect from ITT over 90 years of engineering excellence. ITT collated a substantial amount of industry VOC from top tier military and commercial accounts. This feedback arrived from industry leading ICS customers, pioneering products in their fields including satellites & missiles, test and medical equipment, and tactical battlefield gear. Using this information and leveraging our historical product expertise, ITT engineered a product meeting our customers defined mix of Design, Functionality, and Flexibility. The result of this process represents our innovative new product line, Trinity. Offering three coupling methodologies {threaded, bayonet, and breakaway} and a highly engineered design, this innovative product reduces weight and size without sacrificing robust environme ntal performance or reliability. ITT ICS is proud to introduce our exciting new Trinity product line, engineered to the stringent qu ality standards for which ITT is world renown. Pogo pin/pad technology. Touch pad contacts increase ease of cleanability, highly desireable in harsh environments. Split tine contact design provides proven reliability in harsh environments Double start threads prevent thread damage and allow full connector mating in 1.5 turns. Durable design ideal for harsh shock and vibration environments. Intergral band platform allows direct attachment of cable shield to connector. Master key and 2 secondary keys allow multiple clocking positions MKJ connector provides significant size and weight reduction while providing electrical and mechanical characteristics of larger connectors Connector uses size 23 contacts accepting #22 to #28 wire. Contact spacing is reduced to 0.076 inches providing a compact yet robust package. Breakaway design incorporates a simple push/pull mating mechanism allowing quick connector disconnect.

B-31www.ittcannon.com Dimensions shown in inches (mm) Specifications and dimensions subject to change BMini Circular MKJ Series Connectors Technical overview The Trinity MKJ family of mini circular connectors provides 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 MKJ series connector’s shell s and jam nuts are available in high quality aluminum alloy or corrosion resistant steel per AMS-QQ-S 763. The MKJ series comes with rear accessory thread or integral band platform for direct attachment of cable shield and overmold. The MKJ series of connectors come with a variety of coupling mechanisms: threaded, breakaway, and bayonet. In addition, a Pogo Pin technology utilizing ITT’s uni que 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 in-line, jam nut, front mount, and square flange mount, and flange mount. The MKJ0, MKJ1, MKJ3, MKJ4, and MKJ5 feature a master key and 2 secondary keys for positive mating with 4 clocking positions available. The MKJ0 conn ec- tor is ideal for everyday operations where size and weight are at a premium. The MJK1 connector uses a double start thread coupling with 1/1/2 turns for a full mate and is ideal for harsh shock and vibration environments. The MKJ3 connector can be fully mated in a 1/4 turn. The MKJ4 connector provides a quick push to mate / pull to unmate disconnect mechanism for fast breakaway connections . The MKJ5 connector utilizes a triple start thread and is fully mated in 1 turn, and is an ideal connector for harsh shock and vibration environments and offers an internal coupling ratchet mechanism along with an EMI grounding spring.

B-33www.ittcannon.com Dimensions shown in inches (mm) Specifications and dimensions subject to change BMini Circular Electrical specifications for the connector 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 - #28 AWG wire and allow the contact spacing to be reduced down to 0.076 inches. The connector’s Fortron dielectric insulating material can accom- modate from 3 to 85 contacts in various shell sizes. This high density packaging, along with a reduced wall thickness and scoop, allows a dramatic decrease in size and weight of the MKJ connector while retaining the approximate mechanical and electrical characteristics of heavier and larger Military Standard Enviromental connectors. The connector is capable of operating between -55 degrees Celsius and +150 degrees Celsius and can be mated up to 2,000 cycles. Maximum electrical current is 5 Amps and maximum voltage at sea level is 500 VAC RMS. Max. Voltage
