Configurable Kelvin Contactor New - Johnstech

NewConfigurable KelvinContactorLEADED ROL 200K (Kelvin) SERIES CONTACTORFor QFP, SO, SOT, and Other Leaded-Style ApplicationsUltimate Performance. Configurable Design.The Johnstech Leaded ROL 200K Series configurable Contactor is theultimate high performance engineering and production Kelvin solution. Idealfor high power and precision analog devices that require very tight test guardbands,this Kelvin solution delivers unprecedented mechanical and electricalperformance, flexibility and value.Solid Force Contact and Dual Touch Sense DesignThe Leaded ROL200K guarantees a perfect,high current, low resistance connection everytime. Its design is a unique combination of ourtraditional high current solid Leaded ROL 200Contact (the Force) and a dual touch, flexibleSense Contact that surrounds the Force onboth sides. This design ensures a good Kelvinconnection regardless of device variations.Self Cleaning Wipe ActionTwo self cleaning features ensure that the Leaded ROL200K deliversthe lowest and most repeatable Kelvin contact resistance available on themarket today. The Force Contacts include the oxide removal wipe action ofJohnstech’s patented ROL technology, which automatically prevents surfacedebris build-up on the Contact tip. In addition, the Force and Sense work incombination to remove debris between the two Contacts. These inherent wipefunctions provide long Mean Time Between Assists (MTBA) and Contact life,lowering the overall cost of test.Field Configurable DesignWith its unique configurable feature, the Leaded ROL200K Kelvin Contactorlowers overall acquisition cost and provides the ultimate in customer flexibilityand operating value. The “Kelvin Ready” design allows you to configureand reconfigure your Contactor for standard contacting, “Selective Kelvin”or full Kelvin testing. Parts can be tested with both Kelvin and non Kelvinrequirements.Why Kelvin?Kelvin measurements are theultimate connection for low level,low frequency measurements. In thefour-wire Kelvin bridge configuration(shown below), a current source isapplied with one pair of wires (Force),while the voltage is measured acrossthe DUT with the other two (Sense).By separating the Force and Sensecircuits, the current flowing throughthe Sense leads becomes negligible.As a result, the voltage accuracyis only limited by the internalimpedance of the voltmeter (typically10 to 100 MΩ). This gives an inherentvoltage accuracy of parts per million.RloadRcontactSense HISense LOForce HIForce LORcontactYour Contact For High Performance.
