This combination Honeywell inductive proximity sensor FYAB8A1-2 and MC Technologies, Inc. SPEED SENSOR PS-112 came off working equipment.  It's internal 10 amp power relay is activated by the adjustable speed sensor control which picks up its signal from the proximity sensor to trip normally open and/or normally closed circuits.
 

You can trip relays by speed parameters without need for expensive sophisticated devices requiring special programming knowledge.  Just manually set your limits by the proximity pluses the sensor picks up with a screwdriver on the turn dial and you’re done.
