Rotational speed sensor A5S1DD4

Hall effectnon-contactthreaded

•SIL3/IEC 61508:2010 certified by TÜV •Detection of rotational speed and direction of rotation with two phase-shifted speed signals •in Hazardous Areas Zone 0 or 1 •Dual Channel, •the output displays the rotational speed as a twin-track frequency signal (phase shifted) •Suitable for external direction detection with enhanced safety •Air gap to the target/pole wheel up to 2.5 mm (depending on the profile size) •Differential principle diminishes the influence of external magnetic stray fields and machine vibration •Sealed stainless steel enclosure > 200 bar pressure to sensor tip •Available for connection via tight plug, or with firmly attached cable (PVC or Teflon® insulated) •Powerful square wave output signal equally high over the entire speed range •Sensor short circuit proof and protected versus polarity error •Accepting fine and coarse profiles, as gear wheels, slots, cams, holes in any ferrous material •Requires Isolating Barrier D461 •For installation in hazardous areas as intrinsically safe operating resource •ATEX/IECEx certified for Ex ia IIC T4/T6 Ga •UL/CSA certified for Class I, Div 1, Groups A, B, C, D •EAC certified for Ex ia IIC T4/T6 Ga Benefits •Contact-free with a large air gap, so the potential for damage is eliminated •Wear-free due to its unique design principle •Maintenance-free during Lifetime, therefore minimized TCO •Unsusceptible versus external magnetic stray fields and machine vibration •Operates down to zero speed •Can not be damaged by faulty wiring •Almost every target profile can be used •A5S1 sensors do not influence each other, no mounting distance in between is required
