ROL 200 Contactors are ideal for
Manual Device Evaluation, Lab Testing,
Prototyping and Characterization
• Designed to test to 20 GHz
• Reliable and repeatable results
The “rolling contact” design of the
ROL Contactor, which creates a
self-cleaning wipe action, provides
extensive Production Test benefits:
• Consistent Contact Resistance
• Optimized Electrical Performance
• Higher First Pass Yield
• Repeatable Site-to-Site Performance
• Longer MTBA (Mean Time Between
Assists)
• Prolonged Load Board Life
• Simple Maintenance & Rebuilding
• Improved OEE (Overall Equipment
Efficiency)
• Lower Overall Cost of Test
• Lab Performance correlates to
SL-VCMA
