The inductive series ISDT is a heavy duty, IP65 rated displacement transducer featuring high accuracy and extremely long life. Internal electronics facilitate simple field integration by supplying a proportional analog output that requires no further signal conditioning. Input voltage can either be 24 V or ±15 V. Internal shaft (armature) spring return acts to maintain shaft in the extended position. Available in cable or connector version. Standard version features IP65 protection, IP67 protection is optional.
