New, compact 17-bit absolute encoder
Designed as easy replacements for older, less capable models, Smart Abs is even smaller than its closest competitor which is only a 15-bit encoder.
Better performance at lower cost is provided by the new, true 17 bit Smart Abs(r) encoders from Encoder Technology Designed as easy replacements for older, less capable models, Smart Abs(r) is even smaller than its closest competitor which is only a 15-bit encoder

SSI-output 17-bit Smart Abs encoders available
Now the performance and cost benefits associated with the true 17-bit Smart Abs encoders from Encoder Technology are available to a much wider design community thanks to the introduction of new models
Encoder range covers all requirements
One of the main benefits of the new MEH series of hollow shaft encoders from Encoder Technology is its exceptional breadth making it a product suitable for all levels of sophistication.
High performance stepper motors now cost less
Tamagawa has introduced a range of stepper motors which compare favourably with other high performance models but at much lower cost.
This highly accurate product is available both single-turn (17 bit) and multi-turn (33 bit) versions.
The range is manufactured by Tamagawa - a world leader in position sensing technology - and developed as a joint venture with Matsushita motors.
Historically, a 17-bit encoder could be up to 600mm in diameter and cost anything up to ?4,000.
Smart Abs(r) is available as small as 35mm in diameter and typically costs a less than a tenth of the price.
It has been developed in line with ever increasing market demand for high speed, high accuracy positioning devices for robotic applications.
Maximum speed is 6000 rpm and positioning accuracy of ñ 1/2 bit.
This latest introduction from Encoder Technology is especially suited to this type of application as it features a dual mode signal output.
Naturally, as speed increases so does the data count.
Smart Abs(r) maintains its high accuracy by employing an incremental signal at low speed and a lower resolution absolute signal at higher speeds.
This allows consistently precise positional feedback data across a wide range of dynamic conditions.
The encoder's second smart feature is its E2PROM which allows set-up parameters to be easily stored.
To ensure the encoder shows a true representation of the position of the shaft, the encoder and drive have to be accurately co-ordinated.
This is time-consuming and a procedure which has to be repeated each time a new encoder is fitted.
This useful Tamagawa E2PROM feature allows the user to input set-up data, serial number of the encoder and other identification information.
In the event of a replacement being needed, the new encoder can therefore be supplied with factory-set parameters for quick installation.
Additional customer data can be freely stored with up to 640 bits of memory available (8 bit x 80 addresses). Request a free brochure from Encoder Technology ...
