THE PT5600 model string encoders from Celesco consist of industrial rotary encoders mated to Celesco's durable linear cable reels.

String encoders are commonly utilised when the end user needs a linear measurement, but requires a signal output provided by a high resolution incremental or absolute encoder.

Available from IDM Instruments , the PT5600 model string encoder provides the user with a variety of linear measurement ranges from 10 to 250 inches, as well as four different measurement cable directions.

The encoder can utilise any type of incremental or absolute encoder, including many well known encoder brands. The PT5600 units support the common 2.0 and 2.5 inch square flange mount encoder mounts, as well as the 60mm face mount encoders; other sized encoder mountings are also available.

The encoders provide all the common digital outputs, such as quadrature, 5V line driver, universal line driver, SSI, and Devicenet.

The PT5600 consists of a cable spool that is coupled to the encoder shaft: the spool translates the linear cable motion into the rotary motion of the encoder. The design results in eight inches of linear measurement per encoder shaft turn.

The industrial-grade devices stand up to harsh and challenging environments. The robust design of the encoders makes them suitable for applications such as die cast, valve positioning, material testing, and stage positioning.

The systems have been engineered for reliability and provide quick, easy, and trouble-free installation, where cable alignment is not a critical parameter.
