ASO´s Safety contact mat ASK is designed for safeguarding sections of hazardous areas where working machinery may present a potential danger. Pressure on the mat triggers a control signal to immediately stop a device thereby averting any potentially dangerous situations. The quick-action signal is sent via a surface area switch design that is totally encased in polyurethane to insure impermeability to moisture. Optional surface materials such as aluminium, stainless steel or oil resistant coverings are available to ensure precise installation. In special cases these contact mats may be used as switch mats in applications such as controlling on automatic door.
