熔斷器（fuse）是指當電流超過規定值時，以本身產生的熱量使熔體熔斷，斷開電路的一種電器。熔斷器是根據電流超過規定值一段時間后，以其自身產生的熱量使熔體熔化，從而使電路斷開；運用這種原理制成的一種電流保護器。熔斷器廣泛應用于高低壓配電系統和控制系統以及用電設備中，作為短路和過電流的保護器，是應用最普遍的保護器件之一。

編碼器（encoder）是將信號（如比特流）或數據進行編制、轉換為可用以通訊、傳輸和存儲的信號形式的設備。編碼器把角位移或直線位移轉換成電信號，前者稱為碼盤，后者稱為碼尺。按照讀出方式編碼器可以分為接觸式和非接觸式兩種；
由一個中心有軸的光電碼盤，其上有環形通、暗的刻線，有光電發射和接收器件讀取，獲得四組正弦波信號組合成A、B、C、D,每個正弦波相差90度相位差（相對于一個周波為360度），將C、D信號反向，疊加在A、B兩相上，可增強穩定信號；另每轉輸出一個Z相脈沖以代表零位參考位。
由于A、B兩相相差90度，可通過比較A相在前還是B相在前，以判別編碼器的正轉與反轉，通過零位脈沖，可獲得編碼器的零位參考位。編碼器碼盤的材料有玻璃、金屬、塑料，玻璃碼盤是在玻璃上沉積很薄的刻線，其熱穩定性好，精度高，金屬碼盤直接以通和不通刻線，不易碎，但由于金屬有一定的厚度，精度就有限制，其熱穩定性就要比玻璃的差一個數量級，塑料碼盤是經濟型的，其成本低，但精度、熱穩定性、壽命均要差一些。
