Avtron M4-1 Encoders offer NEMA 56C face or flange (flowerpot) mount, and M4-2 models offer foot mounting, using a solid steel 5/8” industry standard shaft coupled to the load or motor. M4 heavy mill duty encoders are designed for use in mill environments with water, oil, moisture, and dirt. M4 encoders offer a huge variety of connector options to replace virtually any existing tachometer or encoder. For severe duty applications, select M485 solid shaft encoders.
