Johnstech International Corporation announced the release of its “Configurable Kelvin” Pad ROL 200K Series Contactor. Suitable for testing high power and precision analog devices that require very tight test guard-bands, this Kelvin solution delivers desirable mechanical and electronic performance and flexibility. The Pad ROL 200K features a solid force contact and dual touch sense design. This provides a high current, low resistance connection every time, regardless of device contact variations, according to the company. Two self-cleaning features help ensure the Pad ROL 200K delivers low and repeatable Kelvin contact resistance. Its oxide removal wipe action prevents surface debris from accumulating on the force contact tip. In addition, the contactor’s force and sense work in combination to remove debris buildup between the two contacts. This helps extend mean time between assists (MTBA) and contact life.
