Incremental Wire Rope Sensor Series S501D

In the wire sensor series S501D, the mechanical detection of linear movement is done by the pretensioned cable. Inside the sensor, the wire is wrapped on a drum which is tensioned by a helical spring. Pulling the cable, the linear movement is transformed into a rotated movement. An incremental encoder flanged on the drum converts the movement into counting pulses in TTL level. The encoder can be chosen between 500 or 1000 pulses per revolution. Depending on the drum diameter (three types are available) the resolution is between 2,5 or 10 pulses /mm. The flexible mechanical coupling of the wire construction makes the S501 suitable for application in which conventional linear transducers cannot be mounted to the measurement object. With an extended wire, the S501D sensor can be installed in appropriate distance in case of very rough environmental conditions. The robust construction in IP65 protection compliments the high price performance ratio of the S501D wire sensor.
