Electronic Connectors

Cylindrical push/pull connectors

Precision-engineered cylindrical push/pull connectors feature matte-chromated metal shells in different sizes. Inserts are made of various materials, including PEEK, LCP, PBT, and Teflon. Steam autoclaving is possible with connectors having PEEK or LCP inserts. A broad range of contact arrangements and contact styles offers the flexibility to address all design challenges. Contacts include signal, power, coaxial, fiber-optic, and air and fluid couplings. ODU-USA, 451 Constitution Ave., Unit A, Camarillo, CA 93012.

Microminiature connectors

A threaded metal housing is now available to fit all three shell sizes of a series of electronic connectors. The lightweight housings offer a high degree of durability and mechanical integrity. An O-ring is available to ensure a water-tight seal. Both the plastic-and metal-shell versions are polarized to prevent mismating. The units provide high reliability on a 0.050-in. centerline. They are suitable for medical applications requiring rugged durability and reliable performance. Omnetics Connector Corp., 7260 Commerce Circle E., Minneapolis, MN 55432.

Insulation displacement connectors

Disconnectable, insulation displacement connectors feature a 2.5-mm pitch and a height and width of only 11.3 x 4.1 mm. Their small size and low cost make them especially suited for high-density electronic equipment. These insulation displacement connectors are offered with 2 to 13 circuits of AWG #28-26-24 wire. Current rating is 2.0 A ac/dc at 250 V ac/dc. Contacts are phosphor bronze, tin plated. A metallic strain relief secures the wire to protect the IDC connection from vibration, impact, or other external forces. J.S.T. Corp., 1957 S. Lakeside Dr., Waukegan, IL 60085.

Circular connectors

A company designs, manufactures, and distributes an extensive selection of electronic connectors for applications in medical electronics. More than 30 intermatable sealed and unsealed body types are available for cable and panel mounting. Contact configurations include coaxial, triaxial, multipole, mixed, high-voltage, and thermocouple. Standard and custom designs are available. The connectors feature precision-machined shells of brass, stainless steel, or aluminum, as well as high-performance plastic-shell versions. W. W. Fischer Inc., 115 Perimeter Center Pl., Ste. 1060, Atlanta, GA 30346.

Waterproof connectors

A series of high-performance waterproof circular connectors have been developed for interfaces used with a variety of electronic equipment. The JR-W connectors are also corrosion resistant in order to be used even in adverse environments. Plated with black chromium, the connectors offer smooth connections provided by five guide points. Various shell sizes and core numbers are available. Hirose Electric Inc., 2688 Westhills Ct., Simi Valley, CA 93065.

Binding posts

Binding posts are available with a selection of red, white, blue, yellow, black, or green rings embedded in the thumb nuts to ensure ready circuit and polarity identification. The Custom Color Ring 5-Way binding posts feature gold-plated brass current-carrying parts that provide maximum conductivity and corrosion resistance. Miniature fluted-nut types are rated for 15 A, 1000 V working. Standard hex-nut and fluted-nut types are rated for 30 A, 1000 V working. Hex- and fluted-nut types with larger studs are also available. Warner Electric, 383 Middle St., Bristol, CT 06010.

Waterproof locking ac power connectors

Locking ac power connectors are designed for test and measurement, computer, lighting, and industrial applications. The PowerCon system consists of the NAC 3 FPA A-type for power inlets and the NAC 3 FPB B-type for power outlets. Each offers a three-pole connection system with contacts for live, neutral, and protective ground handling power up to 20 A/240 V. Design specifications include meeting the safety requirements of prevailing international and European standards. Neutrik USA, 195 Lehigh Ave., Lakewood, NJ 08701.

Zero-insertion-force connectors

High-density zero-insertion-force connectors offer a pinless configuration. They are used primarily in high-resolution cable arrays for diagnostic ultrasound applications. Available in up to 648 positions, low-inductance Interposer contacts connect to the instrument through printed wiring board technology. AMP Inc., P.O. Box 3608, Harrisburg, PA 17105.

Micro PCB terminal block

According to its manufacturer, a micropitch PCB terminal block with 2.54-mm pin spacing and a 6-mm height is the smallest screw-clamp terminal block available. Rated at 6 A, 125 V, the Model MPT 0.5 has a generous cross section of 0.5 mm² (#20 AWG) and is available in 2 to 12 positions. This terminal block can be used in any application where a wire needs to be brought to a PCB, and it will fit in applications where larger ones will not. Phoenix Contact Inc., P.O. Box 4100, Harrisburg, PA 17111.

Nine-position circular connector

A high-density cable-to-chassis and cable-to-cable nine-position connector is suitable for medical, process control, and test and measurement equipment. The compact plastic connector offers a 1.732-in. mating length and 0.512-in. OD with 1-A crimp or solder-cup contacts. The rugged Ultem housings and low-force contact system provide more than 10,000 mating cycles. Hypertronics Corp., 16 Brent Dr., Hudson, MA 01749.

Circular connectors

Circular connectors are available in single-, multi- or mixed-contact insert configurations including coaxial, triaxial, high-voltage, fiber-optic, fluidic/pneumatic, and thermocouple. They also feature a wide variety of shell styles including standard chrome-plated brass, environmentally sealed versions, and plastic or underwater threaded-type designs. Cable assemblies and custom designs are also available. LEMO USA Inc., P.O. Box 11488, Santa Rosa, CA 95401.
