Avtron M4-(3-9, A-H) Encoders

Avtron M4-(3-9, A-H) Encoders are hollow shaft mounted. Forget tiny hollow shaft optical units that require shaft reduction and special protection! M4 magnetic heavy mill duty encoders can swallow up to a 2 3/8� shaft directly and are designed for use in mill environments with water, oil, moisture, and dirt. M4 encoders offer a huge variety of connector and anti-rotation mounting options to replace virtually any existing tachometer or encoder. M4 encoders are also available in solid shaft/coupled units for foot or face mounting: M4-1 and M4-2. For severe duty applications, step up to the M685 encoder.
