Is this input susceptible to noise?** A: Welcome to TOPENS. TC147 Wired Push Button uses 2 x 22 AWG wire. Usually the extension wire does not exceed 5 meters (16 feet), well-shielded wire can reach 50 meters (164 feet). There was once a customer saying that he used a 100 meter wire (328 feet), but generally we do not recommend our customers to connect that far, as it is easy to have interference.
