hello @kkl yes the sensors can be extended with common audio cables, the 50A sensors are 2.5 mm and the 200A sensors are 3.5 mm. We don’t recommend extending beyond 30ft.
Please post a link for these cable extensions if available. Everything I’ve found on Amazon are either 2.5mm male to 3.5mm female or they are 3 or 4-pole plugs (not the mono as recommended by @mark).
