ESD ELASTIC WRIST STRAP

SPECIFICATIONS

1) WRIST BAND : Elastic adjustable and with conductive filament throughout the entire band length to ensure position skin contact and integrity of grounding. Conductive filament is made up of the conductive wrist strap of 20mm width 32 treat of acrye texture yarn.

2) COILDED CORD : PU(Polyurethene) cable. Coil cord 6ft, 8ft, 9ft,10ft, 12ft or 15ft

3) OUTER DIAMETER : 2.5 +/-0.1 MM

4) RESISTOR: 1 Meg Ohm ¼ watt (Crimped and soldered on top of the socket) +/-2%

5) INSULATION : Polyurethene

5) BANANA PLUG/SNAP BASE HOUSING: Moulded with strain relief and cord restrain. Fixed stainless steel swing copper alloy.

6) FEMALE SNAP : 10mm / 4mm
