The 47201 is a Dissipative Turntable made by Protektive Pak. Made right here in the USA. The 47201 is an ESD protective pad for use with ESD (Static) sensitive assemblies. Each turntable is constructed from durable, 1/4" thick conductive Crosslink Polyethylene Foam. Designed with a very low-profile, these turntables stand only 1" high from your work surface. They freely spin on the galvanized metal turntable. The 47200 has an Octagon shape and is 15 1/2" wide across each flat. Each pad has a weight capacity of 50lb (23Kg) and a Volume Resistance of 1 X 106 to < 1 X 10?per ohms per ANSI/STM11.12 Standards. The electrostatic charges are removed to the ground via the contact on the grounded work surface or via the ground cord attached to a ring terminal.
