Measurement ranges:: 0 mm up to 2.500 mm, 0 mm up to 3.500 mm, 0 mm up to 5.000 mm and 0 mm up to 6.250 mm Resolution measurement ranges WDGA58A: Position per mm Bit per revolution • Exceptionally rugged length sensor • Measuring range: 0 mm bis 2.500 mm bis 0 mm bis 6.250 mm • Interface: SSI • IP65 absolute encoder WDGA SSI ready-mounted www.wachendorff-automation.com/szg81wdgassi The draw-wire encoder SZG81 WDGA SSI was developed for use in harsh environments. The various methods of installation mean high flexibility. It can be used even where space is tight, thanks to its compact dimensions. The SZG81 WDGA SSI can be mounted quickly and with its highly precise mechanics provides reliable accurate length measurement, with all advantages, which result from an absolute lenght measurement. e. g. The position-value is saved, if supply breaks down and is available immediately if supply gets recovered. Doing a reference run isn't necessary. The intelligent spring-suspension and the nylon-coated stainless-steel wire cable guarantee long-service life, even in difficult operating conditions. The encoder is already installed. Multipath transmission Clock sequence Deviation: Less than 0.02 % of the final value. Measuring wire: 0.86 mm of thick nylon coated high-grade steel wire. Wire connection: max. wire speed: Pull out strength: 117.8 System-unit housing: anodised aluminum Weight: SZG incl. encoder max. 2.5 kg Life expectancy: At least 10 million cycles Operating temperature: Storage temperature: nterface Clock input: Clock frequency: Data output: Output code: SSI output: Parity bit: Error bit: Turn on time: Positive direction Set to zero: 101.6 88.9 76.2 B£L rui Encoder SSI via opto-coupler 100 kHz up to 500 kHz up to 2 MHz on request RS485/RS422 compatible gray or binary Angular-/position value optional (even/odd) optional <1.5 s DIR = +Ub O position configuration • Set: Preset = apply +Ub for 2 s Deactivate: Preset = GND Lru Wire completely pull out length Wire not completely pull out 04.83 Electrical Data: Supply voltage: Power consumption: Protocol SSI: Single transmission 81 Encoder Clock sequence All details in mm and dependent on the encoder configuration. 2012-06-22 / Errors and modifications reserved.
