Mil-Spec-Approved Circular Connectors and Commercial Equivalents
Power Connector (PCI), a Trexon company, is a leader in the design and development of standard and custom TacCom connectors. PCI offers an extensive range of products for the defense industry. Power Connector is a Defense Logistics Agency QPL manufacturer of MIL-DTL-55181 and MIL-DTL-55116 connectors which complement its other product offerings of custom filtered and un-filtered power connectors and audio connectors, adapters, dust covers and interconnect components for hand-held and mounted radio systems. PCI’s commitment to excellence and innovation is demonstrated by its top-notch equipment, stringent quality standards, and skillful, dedicated employees.
Smiths Interconnect MIL-DTL-38999 Filter Connectors are designed to meet or exceed all applicable requirements of Series I, II, III, and IV. Filter connectors are intermateable and interchangeable with the standard non-filtered connectors. They address EMI/RFI filtering, and transient protection to meet demanding HIRF and Lightning requirements. Smiths Interconnect’s design strategy for filter connectors is based on extensive experience with filter capacitor arrays and diodes and the understanding of the extreme environmental conditions that can cause a filter or diode to fail or cause a system dysfunction. This design strategy is built on the foundation of system reliability and the efficient use of available space. The capacitor array is protected from thermally induced mechanical stresses by a barrier located between the capacitor array surface and the epoxy filled region. This barrier isolates the epoxy and the ceramic array and prevents damage to the array from the expansion influence of the epoxy.
The JK06 Series from JAE is a waterproof circular connector developed for railway vehicles and related electronic equipment. The JK06 Series is designed in accordance with VG95234 specifications (contact arrangement is compatible with MIL-DTL-5015) and is also compliant with NFF61-030 (French standard for rolling stock) and EN50467 (European standard for railway applications, rolling stock). The JK06 Series is also ideally suited for use in other industrial equipment applications that require a rugged and secure connection.
