LENORD, BAUER & CO. GMBH

Speed sensors from Lenord+Bauer are particularly suited for continuous operation in durable capital goods thanks to the magnetic sensing principle. They detect rotational and linear motion. The sensors are protected against extreme weather conditions, humidity, shock, and vibration due to an encapsulation process and specially developed production methods. Thus they are in compliance with DIN EN 50155 and meet the requirements of protection class up to IP 68. Customised versions by adapting the housing, or different cable and plug fabrication, Lenord+Bauer can implement almost any installation position. Depending on requirement, the sensors generate single or multichannel squarewave signals alternatively as voltage or current signal ranging from 0 to 25 kHz. A standstill signal can also be implemented. On request ATEXprotected product variants, special output signals for functional testing, and sensors with integrated pulse division or pulse multiplication are available.

The compact, highresolution MiniCODERs from Lenord+Bauer have proven their value for speed and position acquisition in highly dynamic applications. They use their full potential when installation situations with little space require a particularly compact, robust and reliable measuring system. The magnetic measuring systems consist of a ferromagnetic target wheel and a scanning unit. Without dedicated bearings, they are completely wearfree and maintenancefree. The optimised circuit and screening technique, and fully encapsulated electronics ensure reliable operation even in harsh environments. High measuring accuracy and compact design have made MiniCODERs the most frequently used speed sensors in highspeed spindles in the world. More than 500,000 pieces are installed, among other things, in machines for highspeed cutting. They are suitable for speed and position detection in all highly dynamic applications and offer now also digital motorfeedback.

Encoders from Lenord+Bauer combine the benefits of a magnetic measuring system with a robust mechanical design. They have proven themselves in a wide variety of applications across the world, even in the harshest of industrial environments. It goes without saying that these encoders offer high reliability and a long service life. They provide exact measurement data even under changes in ambient temperature, fluctuations in humidity, strong vibrations, and condensation. This, however, requires some additional product characteristics such as protective coatings, encapsulation, or condensed water outlet. The incremental magnetic sensors work completely wear and maintenancefree and deliver analogue HTL, TTL or speed signals. The measurement resolution is up to 266,240 increments per turn.

The fully ULcertified positioning system from Lenord+Bauer consists of three individual elements that can be flexibly combined as required positioning drives by the name of SeGMo, the decentralised SeGMoBox control unit for flexible fieldbus integration and the associated hybrid cable solution, including connectors, that is suitable for use with drag chains. The SeGMo drives are complete mechatronic systems with a batteryless multiturn absolute rotary encoder, gear and motor as well as integrated power and control electronics. Lenord+Bauer also offers these for standalone use. With nominal torques of up to 15 Nm, they cover the capacity range typical for secondary axes. Integrate the drives directly into your control system with the function blocks. Alternatively, you can automate up to 17 secondary axes using the decentral SeGMoBox. The box handles the power management for the connected drives and concentrates the interaction with the system control.
