Explosion-Proof Single-Turn Absolute Encoder A/0L80EXS
- Manufacturer: ELCIS Encoder
- Category: Encoder, Absolute Encoder, ATEX Absolute Encoder, SENSORS
7-12 bit single-turn absolute encoder, explosion-proof, ISSeP certified, ATEX Ex d II C T6 according to CENELEC standards, with internal coupling. Suitable for working environments with explosive atmospheres (except firedamp), with markings II 2 G Ex d IIC T6 Gb and D Ex tb IIIC T85°C Db IP6X.
Resolution up to 4096 steps per revolution (12 bits) in Gray, Excess, or custom code. Versions: Parallel Gray or Excess (GP, EP), serial Gray or Excess (GS, ES, RS422 transmission), and analog current (A) or voltage (V) versions, the latter two only with 15 V or 18–28 V power supply and 4096 resolution. Electronics: NPN open collector, NPN open collector + PTC, NPN open emitter + PTC, and push-pull in parallel version; serial SSI; analog 4–20 mA and 0–10 V.
Aluminum housing with internal coupling (max. coupling compensation: axial ±0.25 mm, radial ±0.05 mm, angular ±1°), hollow stainless steel shaft Ø6–12 mm (codes 6, 7, 8, 9 = Ø9.52 mm, 1 = Ø11 mm, and 2 = Ø12 mm), and a weight of 1680 g. Connection via 1 m IP66 cable (CV1, CV7) or 26c IP65 cable end connector (VM5, TM5, only outside potentially explosive atmospheres). The device has a permanently connected cable suitable for a minimum temperature of 100 °C. Options: sealed bearings (Z), stainless steel housing (N), tropicalization (G), and custom options (X). Available in guemisa.es.
