High-temperature and anti-interference rotary encoders specifically refer to those that can work stably in high-temperature environments and have strong anti-electromagnetic interference capabilities. The housing and internal components are made of high-temperature resistant materials to ensure long-term stable operation in high-temperature environments. For example, the housing of some encoders is made of high-temperature resistant materials such as galvanized aluminum alloy or stainless steel.

[0003] A technical solution for a high-temperature resistant magnetic rotary encoder is disclosed in the prior art.
