17272 Datasheet, PDF (1/1 Pages) List of Unclassifed Manufacturers – Full Coverage Non-Marring Foot Grounder

Description:
A
The 17270, 17271, 17272, and 17273 Foot Grounders provide contact with the ESD
floor both under the foot’s sole as well as the heel area, providing a more continuous
Listing #90P1
and reliable path-to-ground. These foot grounders are easier to install than most foot
grounders and are designed for use on standard shoes. The snug, reliable fit can be
easily adjusted to fit the individual wearer. These foot grounders are made from non-marring
three layer high visibility yellow reversible static dissipative rubber with a black conductive inner
layer. The 17270, 17271, 17272, and 17273 are all UL listed. It is a suitable ESD footwear
component in Flooring - Footwear System meeting ANSI/ESD S20.20 when used as the primary
grounding method. It meets <3.5 x 10E7 ohms per ANSI/ESD STM 97.1 Floor Materials and
Footwear-Resistance Measurement in Combination with a Person, and significantly under <100
volts tested per ANSI/ESD STM 97.2 - Floor Materials and Footwear Voltage Measurement in

Our UL listed foot grounders are rated at 250 VAC. It is not recommended to use them where exposure to
line voltages above 250 VAC is possible. Caution: The foot grounder is for ESD control. It will not reduce or
increase your risk of receiving electric shock when using or working on electrical equipment.
