Safedge™ Profiles
Description
The ability of the Safedge profile to out perform competition lies in
its innovative design. It uses a combination of non conductive
rubber and flexible wire cored conductive rubber bonded together
so it keeps bouncing back into shape even after repeated
compressions.
The Safedge profiles come in 3 different cushions factors: 5mm
(0.2in), 19mm (0.75in) and 41mm (1.6in). Cushion factor is the
distance the profile can be depressed after a signal has been
generated. The profiles are also offered with a sealing lip which is
designed to reduce drafts between the profile and opposing surface.
The profiles come in two different materials. Use the EPDM
material in the presence of conductive fluids. The NBR/CR material
performs better in the presence of oils. Review the chemical
resistance chart to help make the best choice of material. If in doubt,
a small sample of the profile should be tested for chemical resistance
before a final selection is made.
The Safedge profile has no rigid internal parts which can “break
through” or cause fatigue failures after prolonged use. The multi-
stranded copper wire core throughout the length of the strip insures
that there are no problems of resistance build up on long lengths.
