932 Magnetoresistive Sensor

932 Magnetoresistive Sensor

Electro-Sensors 932 Magneto Resistive sensors are used with magnetic targets such as Electro-Sensors 60 pole pair magnet wheels, pulser wraps, or pulser discs to provide digital pulse output signals.

These sensors can be used as stand-alone pulse generators, or as an input to all Electro-Sensors products. The 932 Magneto Resistive sensor is 3/4 inch in diameter, with 3/4-16 UNF threads, and is 2-1/2 inches in length. It is supplied complete with a mounting bracket, jam nuts, and 10 feet of 3-conductor shielded cable. It can also be supplied with a conduit adapter allowing it to fit a 3/4 inch conduit fitting.

The 932 can be powered by 8-24 Vdc, has NPN open collector output, and is switched low when the sensing surface is in the presence of a magnetic field, and switched high when the sensing surface is not in the presence of a magnetic field (the null space between the magnets.) This provides a digital square wave output signal. The gap distance between the sensing surface and the pulse generator is dependent on the strength of the target magnets. The signal produced by the 932 is compatible with most PLC Digital I/O cards and with other products requiring a digital pulse input signal.

These sensors are also used in applications where only one magnet is present for counting, function start/stop, or orientation alignment of mechanical or electronic indexing equipment.
