Low-Cost Molded Industrial VRS Magnetic Speed Sensors DESCRIPTION Low-Cost Molded VRS Sensors are designed for use in OEM (Original Equipment Manufacturer) applications. Passive VRS (Variable Reluctance Speed) Magnetic Speed sensors are simple, rugged devices that do not require an external voltage source for operation. A permanent magnet in the sensor establishes a fixed magnetic field. The approach and passing of a ferrous metal target near the sensor’s pole piece (sensing area) changes the flux lines of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding which is attached to the output terminals. FEATURES • Self-powered operation • Direct conversion of actuator speed to output frequency • Simple installation • No moving parts • Designed for use over a wide range of speeds • Adaptable to a wide variety of configurations • Customized VRS products for unique speed sensing applications • Housing diameters: 0.505 in, 7/16 in, 0.292 in, 1/4 in • Housing materials/styles: plastic smooth or threaded • Terminations: Crimp, pin, preleaded • Output voltages: 10 Vp-p to 190 Vp-p The output signal of a VRS sensor is an ac voltage that varies in amplitude and wave frequency as the speed of the monitored device changes, and is usually expressed in peak to peak voltage (Vp-p). One complete waveform (cycle) occurs as each target passes the sensor’s pole piece. If a standard gear were used as a target, this output signal would resemble a sine wave if viewed on an oscilloscope. Honeywell also offers VRS sensors for general purpose, high output, power output, high resolution and high temperature, as well as hazardous location applications. POTENTIAL APPLICATIONS • Engine RPM (revolutions per minute) measurement on aircraft, automobiles, boats, buses, trucks and rail vehicles • Motor RPM measurement on drills, grinders, lathes and automatic screw machines • Motor RPM measurement on precision camera, tape recording and motion picture equipment • Process speed measurement on food, textile, paper, woodworking, printing, tobacco and pharmaceutical industry machinery • Motor speed measurement of electrical generating equipment • Speed measurement of pumps, blowers, mixers, exhaust and ventilating fans • Flow measurement on turbine meters • Wheel-slip measurement on autos and locomotives • Gear speed measurement Low-Cost Molded 0.505 INCH SENSORS (All dimensions for reference only. mm/[in]) Catalog Listing: 2040C (For 230 ºC [450 ºF] capability, order 2040CHT.)
