Operating temperature limits are set by some of IncOder’s electronic parts rather than the basic technique. Standard IncOders are rated -40 or 85oC operation and with a cold option (Product Options 12VCT & 24VCT) for -60oC operation. IncOders can be used outside these limits following qualification by the user. At temperatures >85oC the duration of any elevated temperature should be minimized. At temperatures at or below the stated lower limit, it is recommended to leave the unit powered or allow an extended powered period (>1 minute) before operation.
