the only manufacturer in the world to offer highly flame-resistant TPE type AS-Interface cable with UL CL2 (Power Limited Circuit Cable) and CM (Communication cable) certification for the US and Canadian markets. These cables comply with the UL444, UL13, CSA-C22.2 No.214 standards as well as NEC Article 725. This cable thus provides the optimum conditions for international use in automation technology. The AS-Interface bus provides an efficient connection between simple, binary actuators and sensors (slaves) such as proximity switches, valves and light signalling units and the superordinate central control (master). The AS-Interface bus is an unshielded two-core ribbon cable. It transmits peripheral data and provides the sensors and actuators with energy. The AS-Interface bus allows simple and safe bonding between the components through penetration technology.
