DWG 05
Speed sensors measure rotational movements on involute or rectangular geared sensor wheels in 1 and 2 channel versions. They are available for cog wheel modules from 1.0 to 3.0. They have a max. switching frequency of 20,000 Hz, or 25,000 Hz in special implementations. The speed sensor is also suitable for zero speed. Data transmission using a current loop is used especially in tough environments. It enables use over longer distances, as it is not sensitive to changes in resistance or interference voltages. The DWG 05 in current loop design is therefore ideal for use in rail applications.
