These speed sensors use magnet-sensing Hall Effect IC's to produce a digital pulse signal to interface with speed switches, tachometers, counters, signal conditioners, or PLC's. Hall Effect sensors provide true zero speed operation with square-wave output and immunity to electrical noise.

A pulser disc or split collar pulser wrap with embedded magnets is mounted on the monitored shaft. As the shaft rotates, the magnets pass in front of the sensor causing the sensor to switch high and low, thus producing a digital pulse output. The sensors provide a digital square wave signal with a 50/50 duty cycle when used with pulse generators that have evenly spaced magnets of alternating polarity, such as Electro-Sensors Model 255 Pulser Disc. The recommended gap distance between the sensor and pulse generator is 1/4 inch +/- 1/8 inch. The gap flexibility makes the sensors tolerant of vibration, shaft run-out, misalignment, and industrial environments.

600 Series Proximity Sensors are active digital sensing devices that generate one pulse per pass of an actuating target within their sensing field. No direct contact with target material is necessary. Each sensor is entirely solid state with no moving parts to wear out. The wide range of supply voltages to the 600 Series permits direct interface with low voltage, solid state controls such as programmable controllers and electromechanical relay loads. All sensors are polyurethane or epoxy encapsulated and are provided with a mounting bracket, jam nuts, and 6 feet of cable.

The sensors utilize an oscillator circuit to generate a high frequency field radiated from a coil in the tip of the sensor. When a metal target enters this high frequency field, eddy currents are induced into the target. A detection circuit senses a loss of energy in the oscillator circuit. This low amplitude condition causes the solid state output from the sensor to switch. When the target moves away from the sensing face of the switch, the oscillator regenerates and the switch returns to its normal state.

Features:
• Square-wave pulse frequency output,NPN open-collector
• Zero speed operation with no signal loss
• 5-24 VDC powered

It has a 1-inch NPT conduit opening for wiring, terminal strip for wiring, and is provided with a mounting bracket and 10 ft of cable. The quadrature (bidirectional) option has two sensors and is designed for applications requiring both speed and direction information. Specify vertical alignment when the magnets will pass vertically in front of the sensor face, and horizontal alignment when the magnets will pass horizontally in front of the sensor face.
