TSWP58 from Italsensor is a particularly compact incremental optical encoder with locking collet and integrated coupling for mounting clearance compensation. Typical application is a motor control systems where the assembly of transducer must be particularly compact, the mounting system allows fixing of transducer on a shaft measurement acting on a simple screw. Available fixing diameters are from 10 mm and 12 mm, other diameters on request. Fixing of the body on equipment is executed by three brackets supplied with the encoder. Protection degree IP65 is secured by the front seal made through special O-RING, that helps to prevent contamination of the encoder from dusts and liquids. The possibility of power supply, electronic interfaces and the versatility of the mechanical assembly allow of using this encoder with all systems currently applied in the industrial field.
