The Leaded ROL ™ 200 by Johnstech's ® provides excellent electrical performance and proven mechanical reliability on Leaded Devices. Its production is consistent in contact resistance with an optimized electrical performance, a higher first pass yield that gives a less frequent cleaning. It also increases its mean time between assists because of its prolonged load board life. Its simple maintenance and rebuilding gives a typically backwards compatibility with leaded series 2 mm, improved overall equipment efficiency and lower overall cost of test. Leaded ROL ™ 200 contactors are also ideal for manual device evaluation, lab testing, prototyping and characterization.
