The ASTC0000 is an Inline Amplifier for magnetic pickups and long cable runs. The ASTC boosts magnetic pickup signals by a factor of more than 100 and provides an NPN open-collector pulse output. Low speed input sensitivity is 20mV 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-inch diameter stainless steel shell, with overall dimensions of 0.9-inch (D) X 4.5-inch (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 ASTC. Input and output cables should not be run in conduit, cable troughs or bundles with power or control voltage lines.
