Electronic speed switch PVC100/5000

Features • Easy Installation and Calibration • Rugged - dust,dirt, and grease proof • 115 VAC, 50-60 Hz only • Failsafe Operation • Corrosion-resistant PVC Housing Principle of Operation: The M-Series Switches contain a sensor and switching electronics within the same heavy-duty explosionproof housing. A pulser disc, or an optional pulser wrap, rotating in front of the sensing surface produces a control signal which increases with advancing shaft speed. When the control signal is above the set point setting, the control relay is energized. When the control signal drops blow the set point setting, the relay deenergizes. The relay has Form C Dry contacts rated at 5 amps 115 Vac resistive, so the M100/ M5000 may be used for switching motors and/or alarms. Pulser Disc: The end of the shaft to be monitored must be center drilled to a depth of 1⁄2 -inch with a No. 21 drill and tapped for 10-32UNF. After applying Loctite® or a similar adhesive on the threads to keep the pulser disc tight, the pulser disc should be attached, decal side out, with the supplied 10-32UNF machine screw and lock washer. Pulser Wrap (optional) Pulser Wraps are custom manufactured to fit the shaft they will be mounted on. When the wrap is shipped, four allen-head cap screws hold the two halves of the wrap together. These screws must be removed so that the wrap is in two halves. Place the halves around the shaft, reinsert the screws and torque them to 5 foot pounds. Switch Selection Guide: Refer to the Switch Selection Table, to determine which model is appropriate for your application. The primary difference between the M100 and the M5000 is the set point range.
