Features General Information
Applications
Sinking † or Sourcing † Output — The encoders are avail-
able with Sinking † or Sourcing † outputs. Be sure to order
the type that is compatible with the control's input cir-
cuits. The use of fast response DC inputs is recommended
to minimize missed fast pulsing encoder outputs.
NEMA 4X Option — The NEMA 4X version of the en-
coder includes a stainless steel enclosure and shaft,
double sealed ball bearings, and conformal coating on
both sides of the internal circuit board. This version should
be ordered for applications which involve washdowns,
high humidity or corrosive atmospheres.
