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.
