The DS9100 Touch and Hold Probe Stampings' function is similar to the DS9098 iButton Retainer. An F5 MicroCan will fit completely into the DS9098, but the flange and about one-third of the can will extend out if pressed into the DS9100. As a probe, the DS9100A together with the coiled spring DS9100C allows reading iButtons on contact. With additional pressure, the stiff springs of the DS9100A's outer ring will deflect and grip the MicroCan sufficiently to provide a continuous contact to both the can rim (ground) and the can lid (data). If reading on contact is not required, the cantilever type center contact DS9100B can be used rather than the DS9100C. 1 of 2
