Speed and direction sensors
4Pages

17 I sensori di velocità e direzione rilevano il movimento rotatorio di ruote foniche o dentate di materiale ferroso, fornendo due outputs digitali in frequenza. Attraverso la lettura dei due segnali A e B è possibile stabilire la direzione oraria o antioraria della ruota fonica o dentata. La fase in anticipo o in ritardo tra i due segnali stabilisce il verso di rotazione. Trovano applicazione tipica su motori, differenziali, trasmissioni, turbine, pompe, cremagliere e sono in grado di operare nelle condizioni più gravose. • Elevata precisione e frequenza di lavoro a zero velocità dopo avviamento • Elevate temperature di lavoro da – 40 ÷ + 150 °C • Elevata solidità meccanica • Elevata resistenza alle condizioni ambientali e ai disturbi elettrici ed elettromagnetici • Grado di protezione IP67 • Disponibili in versione NPN, case e connessioni customizzabili The speed and direction sensors detect the rotary movement of phonic or toothed wheels built in a ferrous material, and provide two digital frequency outputs. Reading the two signals A and B it is possible to detect the clock-wise or counterclock-wise direction of the wheel movement. The phase shift between the two signal permits to determine the rotation direction. They find typical applications on engines, differential gears, transmissions, turbines, pumps, racks and are able to work under the most harsh conditions. • High precision, detectable frequency from zero speed after movement start • Operating temperatures: from -40 to +150°C • High environmental conditions and electric/electromagnetic disturbances resistance • IP67 grade of protection • Available in NPN version, with customizable cases and connections Sensori di velocità e direzione Speed and direction sensors Sensori di velocità e direzione ad effetto Hall (1) Sensori di velocità e direzione ad effetto Hall (2) Sensori di velocità e direzione ad effetto Hall 2 wires PAG. 18 PAG. 19 PAG. 20 Hall effect speed and direction sensors (1) Hall effect speed and direction sensors (2) Hall effect 2 wires speed and direction sensors
