The sturdy construction and exceptionally long life of the digital contacting encoder make it a good choice where reliability and dependability are required. The ECW encoder produces a 2-channel, 2-bit gray code quadrature signal which is suitable for digital systems where both magnitude and direction of adjustment must be provided. The 2 channel gray coded signal of this incremental encoder allows the user's decode circuit to sense analog direction of rotation as well as up-down counter capabilities. Temperature range is from -40 °C to +85 °C.
