IFM Electronic New compact speed sensing proximity switch.

April 2006   Evaluation system with integrated sensor. Complies with 94/9/EC (ATEX) group II, category 3D. 3 parameters can be set. Teach function for the switch point. 12 mm sensing range. Ideal in conjunction with a plc. Applications The new M18 compact speed monitor is a processor controlled evaluation system for monitoring rotating or linear movements. It can be used for various applications in the field of conveying technology, in particular for monitoring belt conveyors or bucket elevators. Here it is typically used to monitor if a speed has fallen below a preset value and to monitor blockage or standstill. It is also suited for smaller machines with only little space for mounting sensors. The units can be used according to group II, category 3D, zone 22 (non-conductive dusts). Advantages The compact speed monitor incorporates the sensor and the speed monitoring in one housing. The switch point is set using the teach function. The start-up delay and the output function (NO/NC) can also be matched to the application.
