Please see below our range of Speed Switches
The Synatel PU1DR is a self-contained pulse-input underspeed monitor with an auto-calibrating function, designed to trip a relay when the speed falls below 80% of normal. It is normally used for monitoring the speed of belt-driven conveyors. It contains a built-in proximity switch and requires a suitable rotating target.
It is often used with our Whirligig mounting accessory, which requires only a tapped hole in the shaft to be monitored. The Whirligig incorporates a 2-, 4- or 8-pole target, plus a mounting bed for the PU1DR.
A further accesory is our Magcon magnetic attachment, which can fit to steel shafts and provide the required M12 hole without having to drill the shaft.
