H40 Absolute Shock-Proof Encoder

Built to the same rugged standards as the H40 Incremental
Heavy Duty encoder, this unit features an absolute encoder out-
put up to 13 bits of resolution. Designed to take the rigors of
physically demanding environments, the H40 has a heavy-duty
housing, a 100+ pound bearing, and internal shock absorbers.
When you need absolute position in a really tough environ-
ment— the H40 absolute is what you need.
