Sendix 7000 / 7020 (shaft / hollow shaft)
Push-Pull / RS422
The Sendix 7000 / 7020 incremental encoders offer Ex protection in
a compact 70 mm seawater durable aluminium housing.
These shock and vibration resistant encoders operate flexibly
with a resolution of up to 5000 pulses per rotation; they are also
available with axial and radial cable outlets.
