The 17272 foot grounder provides contact with the ESD floor both under the foot's sole as well as the heel area, providing a more continuous and reliable path-to-ground. These foot grounder is 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. Made from non-marring three layer high visibility yellow reversible static dissipative rubber with a black conductive inner layer. The 17272 is 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 10^7 ohm per ANSI/ESD STM 97.1 floor materials and footwear-resistance measurement in combination with a person, and significantly under < 100V tested per ANSI/ESD STM 97.2 - floor materials and footwear voltage measurement in combination with a person. - Unique design requires no fastening system, flexible material that stretches over most shoes for quick and easy installation. Contact points on foot's sole and heel area, charge generation is generally lower than conventional heel straps due to the continuous path to ground throughout walking motion. Neoprene rubber with no exposed carbon will not mar shoes or floors - reducing maintenance costs of touching up on floors. 18 Inch long, 8 conductive strand nylon polyester grounding tab, additional conductive material provides reliable connection with operator's sweat-layer. 1 megohm series resistor to protect operator from accidental contact with equipment line voltage. Date coded, provides lot traceability to ensure quality control and tracking information.
