SHG-TT Incremental Linear Encoder
Position Sensors & Encoders
The SHG-TT is Sensata | Newall's most popular incremental encoder and is compatible with most major brands of PLC and CNC controls. The SHG-TT provides a differential quadrature output at TTL levels. The periodic reference mark is typically used for homing purposes.
The design of these linear encoders allow installment in almost any position, unlike glass-scale linear encoders, which usually need to be installed with the lip seal facing downwards to prevent contamination. Self-aligning fixing brackets allow virtually effortless scale mounting, needing only a single hole for each set of brackets.
