DESCRIPTION
The Avtron XR47 is a hollow shaft severe duty incremental encoder (also known as a tachometer or rotary pulse generator). It provides a two phase, A Quad B frequency (pulse) output, with complements.
CAUTION The XR47 is designed for use in hazardous applications which require protection from gas or dust ignition for safe operation. Proper selection, wiring and installation procedures are essential to ensuring safe conditions. When mounted to a machine shaft, the XR47 design eliminates the need for shaft couplings, adapter flanges, or accessory mounting faces. The high clamping-force collar holds the XR47 in place, even under severe vibration & shock. A high-performance composite shaft insert provides electrical isolation from motor shaft currents. The shaft insert permits models to fit a range of shaft sizes from 3/4” to 1 1/8” [19mm - 30mm]; additional sizes available upon request. An anti-rotation arm prevents housing rotation while allowing for shaft end float. The XR47 features extreme shock and vibration resistance. Combined with potted electronics and huge bearings, this creates our most rugged hollow shaft encoder for severe duty applications such as oil and gas drilling. The XR47 – –has six signals: (A, B) 90° out of phase, –with complements (A, B). A marker pulse with complement (Z, Z ) is also provided. The XR47 has been evaluated to be compliant with IEC600790:2007, IEC60079-11:2011, EN60079-0:2009, EN60079-11:2012, BSEN 61000-6-4:2007 and BSEN61000-6-2:2005 (Certificates of conformity: TRAC12ATEX0002X, TRAC12ATEX 0003X, IECEx TRC 12.0009X, and IECEx TRC12.0001X.)
THE XR47 IS CERTIFIED FOR USE IN: Group II, Category 2 (ATEX/IECEx Zone 1), Gas Group IIC potentially explosive atmospheres when marked CE 0539 Ex II 2 GD, Ex ib IIC T4 Gb -40°C < Tamb < 80°C and used with an Avtron isolator marked CE 0539 Ex [II 2 GD] [Ex ib IIC Gb] -40°C ± 15%
