Flex Positioner FP40 is designed as a low-cost positioner to hold solder-type, connector tips, and single-ended probes. With HDM1 adapter, it can hold USB microscopes from Dino-Lite. On a metallic surface, the switchable magnetic base can be switched on and off to keep the positioner firmly to its position or be moved or lifted to a new location with ease. On regular work bench, the steel base plate with anti-static rubber at the bottom can hold the positioner steadily.
