Sick - Absolute / Incremental Encoders - Motion Control Technologies

Sick Encoders are used extensively in automated processes where users need to know the positional location on a shaft at a given time. Absolute encoders provide data in digital form and originally standardised on a data exchange protocol with a fixed controller.

With the development of open fieldbus protocols enables fast data exchange over networks to make it common to fit absolute encoders with fieldbus interfaces.

Sick Absolute Encoders

Sick Absolute Encoders are used when the full range of motion in the application occurs within one full revolution (360°) of the encoder shaft. Multi-turn encoders are recommended for application involving multiple revolutions of the encoder shaft.

Sick ATM90 SSI

• Extremely robust, tried-and-tested absolute multiturn encoder with a resolution of up to 26 bits
• Mechanical interface: Through hollow shaft with shallow installation depth
• Zero-set and preset functions via hardware or software
• No battery required
• Electrical interface: SSI with gray or binary code type
• Electronically adjustable, configurable resolution
• Magnetic scanning

Sick Incremental Encoders DFS60

Sick DFS60 line programmable incremental encoders can be programmed to accommodate any value from 1 to 65,536 pulses per revolution (PPR). Sick provide through their software interface, output voltage and zero set position programming. This Sick highly robust encoder features advanced mechanical design and a metal code disc which provides a higher temperature tolerance. The Sick DFS60 encoder is ideal for reducing inventory and enabling the user to create custom resolutions.

The DFS60 Sick encoder has an electrical isolation between motor shaft and the encoder. The DFS60 has a feature which substantially increases interference immunity and reliability and can be used in harsh ambient conditions in any industrial application.

Sick Incremental Encoders

Sick Incremental Encoders are used for asynchronous motors requiring no absolute rotor position. These Sick Encoders are primarily used for speed control. Sick incremental encoders generate impulses which correspond to position, angle and number of turns.

Sick incremental encoders contain a disc with a defined number of lines on it. The number of lines on the disc determines the resolution capabilities. The particular position of the encoder is determined by counting the impulses from reference points. (A reference run is required to determine the absolute position).

VFS60

• High-resolution incremental hollow shaft encoder
• Number of lines, electrical interface and zero pulse width programmable by customer
• Excellent concentricity
• Exceptional robustness is achieved through large distance between the ball bearings

Sick Positioning Encoders

Sick Positioning Encoders, distances and angles when precise positioning is required (an encoder is unbeatable). For distance measurement applications, the resolution of the encoder is in the micrometer range and when making angular measurements, it is equivalent to a few thousandth degrees. The Sick line of encoders include; absolute, non contact length measuring systems, wire draw encoders and compact measuring wheel encoders.
