Dynapar ACURO absolute encoders

acruo-2

The Danaher Industrial Controls Group (DICG) announced an expansion of its Dynapar ACURO series of absolute encoders with two new models that incorporate the company’s new opto-ASIC technology platform. ACURO is already a market leader in several key performance metrics, such as communication compatibility, networking speed, high resolution, and lowest current draw, among others.

The application / function are as follows:
The new opto-ASIC platform extended throughout the ACURO line now provides advantages that make absolute encoder technology applicable to a wider range of motion control and servomotor feedback applications. The new ACURO 36 and ACURO 110 models extend the ACURO series to applications in the small motor, packaging and textile machinery, and medical equipment sectors.

Absolute encoders improve machine reliability because, unlike incremental encoders, they always know their position, even at startup or after a power failure. DICG technology and manufacturing breakthroughs have reduced the cost of absolute encoders, so that they are now finding acceptance in every kind of application, not just the high end, demanding few.

Broader range of sizes – Only 36mm in diameter, the new hollowshaft ACURO 36 encoder is more than a third smaller than previous models in the ACURO line. At 110mm, the new hollowshaft ACURO 110 encoder accepts shaft sizes up to 50mm. Both are available in motor drive or standard industrial versions.

Low-profile gears shrink size, increase reliability – The ACURO 36 is one of the few encoders that use a gearbox instead of a battery to provide multiturn resolution. The low-profile mechanical gearbox allows a lower installation height than battery-buffered counter solutions.

Thin as a dime, the gear set facilitates an installation depth of just 31 mm – one of the shortest in the industry. Small encoders are especially important to motor OEMs, who are under pressure to continually shrink their designs.

In addition, the gears eliminate dead batteries as a potential source of downtime, and eliminate the need for battery maintenance. Running at speeds up to 12,000 rpm, the gear set is nonmagnetic and immune to interference in such applications as welding or motors equipped with powerful brakes.

New OPTO-ASIC generation platform:
The ACURO 36 and ACURO 110 encoders are based on DICG’s new generation platform based on opto-ASIC electronics, into which multiple functions are highly integrated. ACURO was engineered for field dependability, re-designed from the predecessor’s 150 parts and five circuit boards to less than 30 parts and just one board. Reliability is enhanced by minimizing the number of printed circuit boards and soldered connections. The new electronics also enabled Danaher designers to increase the temperature specs on the motor drive version to an industry-leading 120 degrees C – ideal for today’s smaller, hotter running motors.

The ACURO Series has the lowest current draw of any absolute encoder, at just 45mA for the single-turn version and 85mA for the multiturn version.

The new platform is consistent across DICG’s manufacturing plants worldwide. Globally based companies are assured of receiving the same design encoder no matter which region it was manufactured in. This allows company managers to reduce costs through component standardization.

The most communications protocols -The ACURO Series encoders can communicate with any type of control system using common formats, ranging from parallel to such field buses as profibus, DeviceNet, CANopen, CAN Layer2 Interbus, and SSI.A 2048-step sine/cosine signal (1Vpp) is also available for dynamic control. No other encoder offers as many communication options.

Network speeds five times faster:
The ACURO Series was the first to use the new BiSS (Bidirectional Synchronous Serial Interface) protocol. This freely licensable, open-standard protocol supports networking speeds five times faster than proprietary encoder protocols. Using the BiSS protocol, engineers free themselves from restrictive, proprietary bus standards, and achieve data throughput up to 10Mbaud using standard drivers and cables longer than 50m.

As BiSS is all digital, it eliminates the added cost of A/D converters needed in drive systems that connect to encoders using proprietary protocols. BiSS is hardware-compatible with the SSI protocol, simplifying integration.

Differentiate features are:
High accuracy:
The ACURO 36 offers up to 12-bit multiturn and 22-bit single turn resolution – one of the highest accuracy encoders on the market. The ACURO 110 offers 17-bit single turn resolution. High resolution allows precise control of machine motion and increases machine reliability.

More diagnostics than any other encoders:
The new ACURO Series offers more built-in diagnostics and alarms to monitor current and temperature than any other encoder. Optical sensors internally monitor the amplitude of the encoder signals, and exceeding the limit values will result in warning messages. A single-step code check ensures that the encoder signal reflects the recorded turn, bit by bit. The internal signal processing function checks each individual increment for possible occurrence after the previous event. Any violation of this rule, possibly due to disk breakage or mechanical overload, will lead to an alarm.

In addition, a self-monitoring feature checks the operating hours and signals a warning message to initiate preventive maintenance. What’s more, the BiSS protocol can report operation information that can be used diagnostically, such as torque, temperature, and acceleration.

Hyde Park CT1000 Series

Ultrasonic Counting Sensors SUPERPROX®

CT1000 Series Counting Sensors. These are able to count separated, staggered, back-to-back, irregular shaped, and “patterned” bottles with a high degree of accuracy. They operate in the harshest environments.

Now there’s accurate counting of containers over a wide range of sizes, even in the presence of “dither” or jiggling back and forth.

Accurate counting of containers on single-file conveying systems has challenged the container manufacturing, food processing and packaging, beer/beverage, and pharmaceutical industries for many years. The Model CT1000A series is an ultrasonic sensor designed especially for achieving accurate container counting.

The Model CT1000A ultrasonic counting sensor counts separated containers as well as those moving back-to-back at line speeds up to 2000 containers per minute. The accuracy is maintained in the presence of line stoppages, reversals, and container jiggling in front of the sensor. The sensor provides a setting for large versus small container sizes, and regular versus irregular container shapes.

The Model CT1000A sensor is capable of counting various size containers with a single setting of the sensor as long as the proper spacing between the rails and containers is maintained and the distance from the sensor to the containers is not changed.

This Feature eliminates the need to stop the conveyor line and readjust the sensor each time there is a change in the container size or material.

Made of tough ULTEM®, the sensor measures 139.7 mm (5.50″) long x 66.5 mm (2.62″) wide x 78.7 mm (3.10″) high. With protection ratings of IP67 and NEMA 4X (indoor use only), the sensor resists most acids and bases, including most food products. It is sealed to withstand dusty, noisy, non-condensing-humidity, high-pressure, wash-down environments typically associated with beverage-filling operations. The transducer face of the sensor is made of silicone rubber.
