RSF Electronics - LIA SERIES

Exposed Linear Encoder with Signal Control

Easy mounting as a result of large mounting tolerances
Insensitive to contamination due to dual optical sensors
High traversing speed
Integrated subdividing electronics in the encoder head or in the 15-pin D-sub connector
Up to times 100 interpolation (before quadrature)
"True" Reference Mark (accurate and repeatable from both traversing directions)
Dynamic Amplitude and Offset Control
LIA 22: Two independent optical end of travel switch signals
LIA 21: Position of Reference Mark selectable via switch signal
LIA 21: One switch signal for end of travel functions
SINGLEFLEX or DOUBLEFLEX steel scale tape option
