Microminiature Circular - .050" Contact Spacing MICRO-K microminiature circular connectors are rugged yet lightweight - and meet or exceed the applicable requirements of MILDTL-83513. Applications include biomedical, instrumentation and miniature black boxes. Standard MIK connectors are available in two shell sizes accommodating two contact arrangements pre-wired to your specific requirements. MIK: Accommodate up to 55 contacts on .050 (1.27) centers (equivalent to 420 contacts per square inch). Five keyway polarization prevents cross plugging. The threaded coupling nuts provide strong, reliable coupling. MIK receptacles can be either front or back panel mounted; in back mounting applications, panel thickness of up to 3/32" can be used on the larger sizes. Maximum temperature range - 55C to + 125C. MICRO-K radios, military gun sights, airborne landing systems and medical equipment. Maximum temperature range - 55C to +125C. MIKM: Similar to our MIK, except has a steel shell and receptacle for improved ruggedness and RFI resistance. It accommodates up to 85 twist pin contacts. Maximum temperature range - 55C to + 125 C. MIKQ: A quick disconnect metal shell and receptacle version that can be instantaneously disconnected yet provides a solid lock when engaged. Applications include commercial TV cameras, portable Specifications STANDARD MATERIAL AND FINISHES ELECTRO/MECHANICAL FEATURES MIK MIKM MIKQ Thermoplastic Stainless Steel Brass Stainless Steel Passivated Stainless Steel Passivated Brass, Electroless Nickel Plated* Insulator Glass-reinforced Thermoplastic Glass-reinforced Thermoplastic Glass-reinforced Thermoplastic Contacts 50 Microinch Gold Plated Copper Alloy 50 Microinch Gold Plated Copper Alloy 50 Microinch Gold Plated Copper Alloy Shell Coupling Nut MIK No. of Contacts Wire Size 7,55 #24 AWG thru #32 AWG Contact Termination Crimp Contact Rating 3 Amps Couping Threaded Polarization Keyways Contact Spacing .050 (1.27) Centers Shell Styles 0-Wall Mtg. 6-Straight Plug *For plug only Electrodeposited for receptacle.
