Guangzhou SINO L.Digital LTD. is a well-known manufacture of Digital readout system for machine tools in china. Our products have met the strict requirement of European CE safety standards, ISO 9001 certificate, our products had been export for many countries, and always the number one in the world market.our products:digital readoutSDS5VSDS6-2VSDS6-3VSDS3-1Non-linear error compensation; PCD hole positioning on circumference; 200 points auxiliary zero position function; High-capacity ROM disc for storage; Real time coortransmission with RS232; File transmission function through USB; Four coordinate system are adopted in thsi system, namely, machine coordinate system, absolute coordinate system,relative coordinate system and 200 user coordinate system; Metric/British units switching display;Software diagnosis function; AB function to search for the reference point of encoder; Power off momory function.Linear encoderKA series Grating scale linear encoders:KA-300 is the most commonly used standard ruler(TTL electric level),KA-200,KA-500 ia a super miniature thin ruler (respective 16*16mm,20*18mm), it facilitates the use in some narrow placesand the installation of special purpose measuring instrument. KA-700, it is a newest product designed especially for use in oil pressure system and in some spaces where installation is very difficult. KA-800 is a new product that can be connectable for length purpose the Max length can be 100 meters, the appearance of KA-800 will further broaden the application feild of Digital readout devices.KA-300 ( 70-1020mm)KA-500 (70-1020mm)KA-600 (1000-3000mm)Technical Parameters:Pitch: 0.02mm(50 lines/mm)Resolution: 0.5um, 1um, 5um.Accuracy: +/-3um, +/-5um, +/-10um (20℃)Range: 70-3000 meterMax speed: 60 or 120 m/minWorking voltage: +5V (+/-5%) 80mACable length: 3 meters (various length avaliable upon request)Working Temperature: 0-45℃Plug Pin
