Description
The GEL 176/177 absolute linear scale are available in various
configurations. The GEL 176 linear scale is a ring type sensor with an external
magnet. Four different magnets are available to fit any application. The GEL 177
linear scale are available either with external magnet or in a slide version.
The slide version features a swivel joint for easy mounting eliminating
misalignment errors. Both models are using a magnetic sensing principle. Six
different outputs are available; 0...10V and 10...0V, 0...20mA, 4...20mA,
20...0mA, 20...4mA and SSI output. The Synchronous Serial Interface (SSI)
features 25-bit Gray code - industry standard for digital outputs. Designed for
use in harsh environments, the GEL 176 features IP65 protection, the GEL 177
features IP67 protection. Measuring lengths from 50 up to 2000 mm is available
in 50 mm increments.
