Optical encoders cover wide temperature
range
Incremental encoder module provides advanced motion control detection with integrated commutation outputs that are equivalent to those produced by Hall switches.
Avago Technologies has developed a new series of extended operating temperature optical encoders for use in a wide range of applications that require lower resolutions Avago's AEDS-9240 optical encoder series is ideal for use in applications that use brushless DC motors such as industrial printers, textile machines, industrial and factory automation equipment, as well as plotters and tape drives

Dust-tight absolute optical encoders keep it clean
Agilent Technologies has developed its first absolute optical encoder products that provide position information without requiring shaft movement.
Modular encoder is absolutely cheaper
The industry's smallest high-speed "plug-and-play" absolute encoder is claimed to reduce assembly time by half and cut costs for industrial automation systems by as much as 40%.
With the growing demand for improved drive electronics and motor control to help reduce manufacturing costs, improve efficiencies and device reliability, this trend is driving the wide scale use of brushless DC motors in servomotor applications.
The AEDS-9240 optical encoder series, addresses this need by providing designers with an incremental encoder module that provides advanced motion control detection with integrated commutation outputs that are equivalent to those produced by Hall switches.
Avago's AEDS-9240 six channel incremental encoder module has also been designed with two-channel quadrature outputs, and a third channel ungated index output.
It detects rotary position using a codewheel that has an optical radius of 19.00mm to obtain 360 or 720 cycles per revolution.
The ungated index output is a positive index pulse that is generated once for each full rotation of the codewheel.
Each module consists of a lensed LED source and a detector IC enclosed in a small plastic package.
In addition, the encoder module incorporates a highly collimated light source and a unique photo detector array to make the AEDS-9240 extremely tolerant to mounting misalignment.
The AEDS-9240 series of incremental optical encoders are available through Avago Technologies' direct sales channel and worldwide distribution partners. Request a free brochure from Avago Technologies ...
