Contacts for Hi-Rel Connectors: Comparing Technologies

Contact design is critical to the performance of any connector — especially for devices that must function in harsh environments where extremes of temperature, shock, and vibration are to be encountered. Yet there are many different contact styles, and each supplier will claim an advantage. This article aims to set out clearly and concisely the merits and drawbacks of each of the main styles.

High-Speed Backplane Connector System

Samtec (New Albany, IN) has expanded its ExaMAX® High-Speed Backplane Connector System optimized for high-density and high-speed performance. The ExaMAX® header and right-angle receptacle system (EBTM/EBTF-RA Series) is optimized for speeds up to 28 Gbps on a 2.00 mm column pitch or 56 Gbps on a 3.00 mm column pitch. For 28 Gbps performance, this system meets and exceeds OIF-CEI-28G-LR specifications. Return loss compliance is achieved in both 85 Ω and 100 Ω systems due to targeting the 92 Ω specifications and controlling reflections at all geometry transitions within the connector.

Magnetic Encoders

POSITAL (Hamilton, NJ) introduced new models of IXARC magnetic encoders that combine incremental and absolute rotation measurement capabilities in a single, compact package. Absolute encoders provide a control system with a report of the rotational angle and rotation count at a specific point in time; incremental encoders provide a signal pulse each time the encoder shaft rotates by a specified angle. The hybrid encoders are based on the company’s magnetic measurement technology, and offer shock, dust, and moisture resistance. The hybrid incremental and absolute rotary encoders have communications interfaces that support both measurement modes: RS-422, HTL, or TTL for incremental readings; and SSI for absolute measurements. Available multi-turn versions can count up to 64,000 revolutions, while incremental measurements have resolutions as high as 16,384 pulses per revolution.

Planetary Gearbox

GAM (Mount Prospect, IL) offers the SPH inline planetary gearbox with helical gears for dynamic and cyclic applications, as well highspeed and continuous duty applications. It is available in six frame sizes with nominal torque ratings from 15 to 900 Nm. The face width of the gears provides more tooth contact and greater overall torque density. The gears are case-hardened, which imparts strength deeper into the gear. With several output configurations available, machine integration is simplified.

Clutches

U.S. Tsubaki Power Transmission, LLC (Wheeling, IL) announced Cam Clutch unidirectional/ mechanical clutches that lock the inner and outer races through the locking action of cams, transmitting torque in one direction of rotation while overrunning in the other. The cams are made of alloy steel, and the races are made of alloy steel with high surface hardness and core toughness. They are precision-ground to provide concentricity and surface finish for accurate cam rotation.
