GVS series Gear tooth sensor provides speed sensing capabilities using an integrated Hall-effect sensor in conjunction with a permanent magnet which supplies a bias field, this ready-to use pick-up directly senses rotating ferrous gear and other similar gear type target. GVS speed sensor is a non-contact, solid state ferrous detecting device with a switched output. Its unique design provides a low cost solution for a wide range of speed sensing applications, especially those requiring true zero speed performance. This device utilizes a Hall Effect sensor that is internally biased with a permanent magnet and detects the interaction from an external ferrous target. Unlike earlier Hall based products, this device automatically detects changes in target position or symmetry to compensates for these changes. This specialized feature eliminates the need to externally calibrate or mechanically adjust each sensor for optimum performance. In addition, electronic hysteresis built into the device eliminates false triggering due to mechanical backlash and vibration.

AI-Tek has taken its years of experience of designing and manufacturing Hall Effect sensors for engine timing applications and has developed a line of durable products for industrial use.
With multiple standard variations we offer the widest range of standard catalog sensors to meet your various design needs. The design is flexible to easily meet all of your application requirements.
The Hall Effect sensor can sense each change in target movement, regardless of speed, from near zero to 15 kHz frequency range, generating a steady pulse train of frequency proportional to target speed. Typically, each time a gear tooth (or any ferrous discontinuity) passes in front of the sensor the output changes state. This type of sensor is known as a "P" type because it uses N-P-N transistor logic (as opposed to "N" type, which uses P-N-P transistor logic).
Key features to note are:
- Reverse voltage protection, up to -30 Vdc, to prevent damage if miswired
- Higher temperature range of -40°C to +125°C
- Wide range of supply voltage in single design of 4.5 - 24 Vdc
- Two output options of Supply Tracking or TTL Compatible
- Rugged design meeting IEC 77 Standards (European Railroad Applications)

Rotational Speed Sensor Type FUA9192
Optical probe for measurements of rotational speed, designed as retroreflective photoelectric sensor for photoelectric detection of rotational speeds or events.
For evaluation of the pulses, the tachometer probe is equipped with a specific frequency meter module that calculates the number of revolutions per minute from the time period between two pulses. A stable read-out is achieved by averaging over a minimum of 500 ms.
Easy application:
A reflective adhesive tape is attached to the moving part and the probe is aligned with it. For function control purposes a yellow signal lamp at the rear side of the probe will be on when the reflective adhesive tape is recognised.

The 907 XP (explosion-proof) Hall-effect sensor produces a digital pulse signal for use with speed switches, tachometers, counters, signal conditioners, or can be used as a direct pulse generator.
As a pulser disc or split collar wrap (mounted on the monitored shaft) rotates, the target magnets pass in front of the sensor. The Hall-effect sensor switches high and low as it is exposed to the alternating polarity of the magnets on the disc or wrap, producing a digital pulse output.
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, slight shaft run-out, minor misalignment, and other industrial elements. The 907 XP sensors are used in applications requiring explosion-proof ratings, or in applications where the sensor may be subject to abuse.
The sensors can be mounted up to 1500 feet from the control unit - speed switch, tachometer, etc. They are powered by 5-25 Vdc and provide an NPN Open Collector output. The 907 XP sensor has an XLB-3 enclosure which is C.S.A. approved and UL rated for Class I Group D; Class II Group E, F, G; Class III.

Speed sensors are designed for installation in drives as an alternative to the conventional encoders. They are contactless and are equipped with a magnetic scanning system which, in conjunction with a toothed wheel as measuring scale permits the measurement of rotary motion. This solution is exceptionally space saving.
The speed sensors are designed for highly reliable speed and direction measurements starting from 0 Hz and - due their metallic housings - are suitable for even the harshest working conditions. In addition, they tolerate large air gaps between target wheel and sensor element. The sensor elements, the magnet and the integrated electronic system are incorporated in state-of-the-art micro system technology and are fully encapsulated. The design together with subsequent circuitry ensures an electrically and mechanically robust product.
Advantages:
* The miniaturized sensors are dew-point proof, do not wear and are insensitive to dirt, shock and vibration.
* The toothed wheels can be adapted to any machine geometry (interior and exterior diameter, impulse number).
* MiniCoders require no maintenance and thus have a low cost of ownership.
* This extremely flexible system offers you not only long term reliability but also solutions to gain a competitive edge.

Variable-reluctance sensors are preferred for industrial and automotive environments, because they sustain mechanical vibration and higher temperature operation. In most applications, they sense a steel target that is part of a rotating assembly. Because the unprocessed signal amplitude is proportional to target speed, a sensor whose signal-processing circuitry is designed for high speed ceases to function at some lower rate of rotation.
Variable Reluctance sensors are often referred to a 'passive' magnetic sensor because it does not need to be powered. Variable Reluctance sensors are 'self generating'
The variable reluctance wheel speed sensor is basically a permanent magnet with wire wrapped around it. It is usually a simple circuit of only two wires where in most cases polarity is not important. The physics behind the operation include magnetic induction.
