ASTC0000 Product Manual

The ASTC0000 boosts magnetic pickup signals by a factor of more than 100, and provides an NPN Open-Collector pulse output. Low speed input sensitivity is 20 millivolts which permits operation at 1/50th of the 1-Volt Threshold Speeds listed in the Magnetic Pickup Specifications and Ordering Table. The unit is epoxy-encapsulated in a 3/4″ Dia. stainless steel shell, with overall dimensions of 0.9″ D X 4.5″ L including Neoprene strain-reliefs on each end. In installations where long signal runs are to be made it is advisable to keep the ASTC close to the magnetic pickup and make the longer cable run with the output from the ASTC0000. Input and output cables should not be run in conduit, cable troughs, or bundles with power or control voltage lines.
