The ISD25 encoder is a ruggedized hubshaft encoder with advanced phased array sensing technology. This allows the device to be both accurate and robust. It can be applied to a number of HAZ LOC environments when used in conjunction with an IS barrier. The oversized bearings and improved seals make this a great choice for application where a industrial duty encoder may not last.
