IGP Series
Using this potentiometer a maximum angular rotation of 3800° can be converted into a voltage proportional to the angle of rotation, through the medium of a conductive-plastic potentiometer.
This special "heavy-duty" version is designed to measure angular or linear displacement under the most difficult of enviromentat conditions. Simply yet robustly built, these units are suitable for use in all manner of industrial applications and engineering industry.
The cast housing is watertight. The single stage gearing is exceptionally backlash-free. Heavy-duty bearings allow for high axial loading on the shaft; gearwheels or even chain drives may be used directly drive the shaft.
Sealing is achieved through the use of a stepped bush whilst electrical connections are made via plug and socket mounted on the side of the unit.
Special features
- reduction gearing 3:1, 5:1, 10:1
- good linearity 0.1 % (standard)
- long life typically 100 x 106 movements
- mechanical rotation
- robust construction with 10 mm shaft
- Protection class IP 65

Rotary Shaft Encoders are ideal for use on any rotating shaft to provide a digital output signal to tachometers, counters, speed switches, motor controls, or anything requiring a pulse input. Flexible shaft couplings are available as an option to compensate for shaft misalignment, and are recommended for most applications.
Electro-Sensors Rotary Shaft Encoders convert shaft rotation into square wave output pulses. They provide an accurate means of transmitting actual speed information for detecting rate, position, or direction of rotation. The shaft encoder produces an output signal by rotating a disc with clear and opaque segments between a light emitting diode and a photo-transistor sensor. The output signal from the encoder is then converted into a square wave signal by an internal squaring circuit. The number of output pulses per shaft revolution is determined by the number of clear and opaque segments on the disc. Quadrature (bi-directional) models have a second LED and sensor positioned 90-degrees apart to produce two square wave signals.
Features:
- Ideal for Use on Slow Speed Applications
- Provides Precise Pulse Train for use with Tachometers, Counters, Speed Switches and Speed to Analog Converters
- Multiple Mounting Configuration for easy Installation
- Wide Variety of Pulse per Revolution Counts are Available
- Please Specify PULSES PER REVOLUTION (PPR) When Ordering

Incremental Encoder HS15
Performance Benefits:
With high-performance, high-resolution digital feedback in an extremely small package, the new DataTorque HS15 combines the resolution and performance common with much larger encoder packages with the stability of a bearing encoder design.
The HS15 provides a bearing design that simplifies encoder attachment, resulting in a longer service life with less downtime (from feedback device failure). It delivers high noise immunity. In addition, the DataTorque HS15 is cost competitive with modular encoders.
Design Features:
The DataTorque HS15 is miniature in size, only 1.5 inches (38 mm) in diameter and low profile, only 0.87 inches (22 mm) in assemble height, yet it provides resolutions up to 5,000 lines with or without commutation. Output options are single-ended or differential line driver.
The DataTorque HS15 has low supply current requirements. The optional 5 to 26 VDC can help reduce inventory. It is constructed of a conductive carbon fiber composite that provides the EMI shielding of an all-metal housing and the performance of a lightweight robust assembly.

The incremental coder is planned for demanding applications relating to the detection of angles, direction of rotation and speeds. It delivers a signal whose values are in relative connection with the position of reference zero.

Incremental encoder is the term given to sensors for recording changes in position (linear or rotating) that can measure both the distance and direction of travel.
They are also known as optical encoders.
Unlike measuring systems that work continuously, incremental encoders have a solid measure with a repeating periodic counting track. The measurement is based on a directional reference and a count.
|
|
|
Incremental encoders have output signals that repeat over the full range of motion. When the incremental encoder is turned on, the position of an incremental encoder is not known since the output signals are not unique to any singular position.
|
|
The encoders contain a contact-less magnetic sensor system and a precision toothed wheel. The sensor’s magnetic field is modulated by the passing of the teeth of the measuring wheel.
The resulting sinusoidal and co-sinusoidal voltage is evaluated by the integrated electronic and converted to an incremental output and optionally to an additional analogue current output.
Advantages of the magnetic system:
* Unaffected by condensation on the measuring wheel and is therefore the preferred choice for applications, where ambient temperatures change or where the relative humidity is high. (e.g. outdoors)
* Unaffected by oil or dirt penetration.
* The steel measuring wheel is highly resistant to shock and vibration, unlike glass or plastic graduated discs in other systems.
* Excellent reliability over a very long life because it does not suffer from the ageing effect common to optical systems.

Incremental Encoders
At Cleveland Motion Controls, we offer a wide selection of Rotary Incremental Encoders, providing you numerous solutions for a wide range of position and control application requirements.
Many of our customers first find us because their old suppliers furnished them with off the shelf products. That way of doing business caused them to force-fit other vendors' products into their applications. Force fitting a product to a design limits the performance of an application.

MIG – Incremental magnetic pulse generator
STRÖTER has developed an „intelligent“ intermediate flange which considerably simplifies the measurement of speed and sense of rotation as well as the connection with coordinating
control systems. What was previously only possible with time-consuming assembly and addons to drive systems is now possible in an easy and economical way both in new and existing installations.
This MIG magnetic incremental rotary transmitter is designed as an intermediate flange which is simply installed between the motor and the machine flange. This makes the integration of incremental position encoders in drive systems much easier – no matter whether you use it for speed measurement, for positioning control, dosage control or for synchronisation control.

Magnetic Encoders
As market conditions become increasingly competitive, magnetic encoders are seen as a promising incumbent, offering engineers an encoder solution that is small, robust, yet, priced significantly lower than existing absolute encoders in the market today.
A magnetic encoder typically uses Hall effect or magneto-resistive (MR) effect to sense positional information. Avago's magentic encoder with integrated Hall sensors requires a permanent magnet that is firmly mounted on the rotating shaft of a motor. A magnetic encoder operates on a non-contact basis. Thus, mechanical wear is not a consideration.
Avago’s magnetic encoder solution is high performance, designed for use in a wide range of industries that includes industrial and office automation, as well as, consumer applications. Its typical applications includes test and measurement equipment, surveillance and security, printers, fax machines and copiers, white goods and appliances, cable and satellite dish, toys and games, and much more.
