THE EXPLOSION-PROOF ABSOLUTE ENCODER THAT WILL FIT WHERE OTHERS WON’T

Many applications that require the use of absolute encoders are demanding, not just from a performance perspective but also because of the operating environment. An example of this is applications where the encoder has to be explosion-proof due to the dangerous atmosphere in which it operates. Another would be applications that involve harsh environmental influences such as offshore platforms or those that experience huge shock loads of over 100 Gs or even shaft loads of hundreds of Newtons.

The Hengstler AX65 absolute encoder has been engineered to handle all these requirements, and is believed to be one of very few devices that can do this.

Certified explosion-proof, the Hengstler AX65 is built with marine-grade stainless steel and has a shock rating of 200 Gs and shaft load of 300 N. This tough encoder is not only the most compact in its class, it also offers an exceptionally shallow depth and body diameter of only 59 mm. This means it can be installed in applications where other larger explosion-proof encoders cannot be used.

Carrying explosion-proof certification makes it ideal for mines, chemical plants and offshore oil platforms, as well as other applications that require an encoder constructed from marine grade stainless steel. The shaft load rating eliminates the need for load modules, reducing costs.

This device can be installed quickly and easily due to its flexible, quick-connect terminal system. It comes standard with the choice of SSI or CANopen interface, and it is also possible to integrate the CANopen encoder in a ring network configuration.

The Hengstler AX65 is available from Countapulse Controls. The company has a strong customer service ethic and offers strong engineering and technical support.

CYLINDRICAL SENSORS OFFER STRENGTH

Countapulse Controls reports that the Leuze cylindrical sensors offer a higher mechanical strength than the standard sensors. Engineered for particularly arduous conditions, the Leuze 328 series sensor is based on the optical platform of the well-known standard Leuze 318B series, however this new device features a metal sleeve in the housing.

The operational sensors available in the new Leuze cylindrical series, which range from throughbeam photoelectric sensors to retro-reflective photoelectric sensors to light scanners with sensitivity adjustment via teach button, are designed with the option of either a cable or plug connection. An adjustable retro-reflective photoelectric sensor model with a polarisation filter is also available for particularly tricky applications.

With ranges of up to 15 metres (throughbeam photoelectric sensors), six metres (retro-reflective photoelectric sensors) and one metre (light scanners), the new Leuze cylindrical sensors are ideally suited to a variety of applications for object detection in materials handling and packaging technology.

The cylindrical sensors are especially popular for integration into constricted production facilities as well as into assemblies in transport systems or other machinery. In many production processes and internal transport systems, these optical sensors are used for the detection of objects and thereby control processes or partial steps. The highly visible light spot facilitates alignment and two antivalent outputs expand the application options.

The quality engineered and manufactured range of Leuze sensors is available from Countapulse Controls who has been providing sensing solutions to business across southern Africa for more than forty years. This Johannesburg based company also operates a technical hotline to ensure that customers have ready access to relevant applications and operational information.
