Nidec-Avtron Makes the Most Reliable Encoders in the World
When mounted to a machine shaft, the HS45 design eliminates the
need for shaft couplings, adapter flanges, or accessory mounting
faces. The high clamping-force collar holds the HS45 in place, even
under severe vibration & shock. A high-performance composite shaft
insert provides electrical isolation from motor shaft currents. The shaft
insert permits models to fit a range of shaft sizes from 5/8" to 1 1/8"
[16mm - 30mm]; additional sizes available upon request. An anti-
rotation arm prevents housing rotation while allowing for shaft end
float.
The HS45 utilizes magnetoresistive sensors. This proven technology
is ideal for rugged environments since it is immune to many
contaminants that cause optical encoders to fail. All of the HS45
electronics are potted, providing full protection against liquids.
The outputs are protected against short circuits and wiring errors.
DESCRIPTION
The Avtron Model HS45 is a
heavy duty
incremental encoder (also
known as tachometer or rotary pulse generator). Its output is directly
proportional to shaft position (pulse count) or speed (pulse rate). The
HS45 operates down to zero speed and can be used for both control
and instrumentation applications.
CAUTION
Do not utilize HS45 in hazardous locations which
require ATEX, UL, CUL, CSA, or other explosion protection
certification. HS45 is not certified for hazardous
locations. Use XR models for hazardous applications.
