New hall sensor for applications in rolling stock
 
hall sensor for applications in rolling stockBaumer’s new MTRM 16 hall sensor was specifically developed for the contact-free pulse detection of fast-spinning gear wheels. With its robust metal housing it is predestined for the use in harsh conditions. The sensor was particularly optimized for applications in railway gear boxes and therefore meets all of the demanding requirements for the employment in this industry. The very compact hall sensor picks up the rotational direction as well as rpm speed of gear wheels with up to 20,000 pulses per second. Due to the non-contact measuring principle, the sensor is maintenance-free, thereby guaranteeing long-term trouble-free use. At the same time it is very robust and temperature-resistant. Thanks to the completely sealed and coated all-metal housing, the sensor may be exposed continuously to gear box lubrication oils. Its optimized housing design with integrated O-ring allows fast and easy installation. The notably robust housing design qualifies the hall sensor not only for the direct integration into the railway gear box or the engine ...

Tyco Electronics Presents Hall Sensors for Convertible Roof Systems
 
Hall Sensors for Convertible Roof SystemsTyco Electronics: Requirements for convertible roof systems increased dramatically over the last twenty years. The system of textile roofs has been developed continuously and complemented by retractable hard tops since the beginning of the nineties. The complete kinematics has high mechanical tolerances, but the robustness of the complete system must be provided every time. In order to provide availability and accuracy, non contacting position sensors are being used either for on/off position detection or angular positions detection. For a proper working kinematics in a roof system, position and angular sensors are designed in. Depending on the mechanical design, different types of sensors are being used for these applications, such as on/off position detection at kinematics, angular detections at swivel joints, and end position detections at hydraulic cylinders. Separate cable assemblies are used frequently which provide a simple and precise mounting in the complex mounting process of a roof system. For over ten years, Tyco Electronics has provided hall sensor cable assemblies ...

Micronas presenting 3D Hall sensor, Innovative sensor with vertical Hall elements designed for automotive and industrial applications, as well as for use in home appliances
 
Micronas, a leading supplier of innovative application-specific IC and sensor system solutions for automotive electronics, launched the new HAL 36xy family with their HAL 3625 Hall-effect sensor based on Micronas’ 3D-Hall technology and equipped with vertical Hall elements. This technology allows rotation angles from 0° to 360° to be detected directly with minimum measuring efforts. Unlike today’s usual Hall sensors, which use one Hall element to measure at one level only (Z-axis), the new technology allows the detection of an additional X and Y axis. Combining different axes and using the appropriate signal processing, a so-called 3D Hall sensor has been realized. The great advantage of these vertical Hall-effect sensors is that they can be manufactured in a standard CMOS process without additional post-processing. This process delivers products with ultimate quality and reliability, especially for the demanding automotive market. The HAL 36xy product family will include several versions which will also differ in a number of essential characteristics and properties. The first member of this family offered by Micronas will be the HAL 3625 which delivers a ratiometric output format. The 3D Hall sensor HAL 3625 features integrated signal processing. ...

Hall sensors - Show them your teeth
 
Baumer Electric: Hall sensors are particularly well suited for scanning gears and racks made of ferromagnetic materials. Their high resolution allows them to reliably detect gear teeth starting at module level 1. Their maximum switching frequency is 20 kHz, making them up to five times faster than inductive sensors employed for similar applications. Thanks to two phase-shifted signals, Hall sensors are even capable of detecting rotational direction or direction of travel. Hall sensors thus offer themselves for use as replacements for incremental encoders. And since, in contrast to encoders, they contain no ball bearings or other moving parts, the sensors are subject to practically no wear, even at high rotational speeds. The units themselves are vibration and shock resistant. The front face of the M12 full metal jacket made of 1.4305 stainless steel corresponds to protection class IP 68. The operating temperature range lies between -40 °C and +120 °C. Hall sensors are designed for employment in harsh industrial environments subject to extreme dust and oil contamination. Examples of such applications include textile, tobacco and cement processing as well as agricultural equipment. Keyways at either housing end allow them to be easily adjusted to the gearing being scanned. ...


High performance DUAL OUTPUT contactless rotary position sensor
 
Penny + Giles, the position sensor specialist, has launched a new contactless rotary position sensor with dual outputs, SRH280DP. The new sensor incorporates a factory programmable Hall effect sensor and has two outputs that can be programmed individually. As a result, it provides reliable and accurate rotary position measurement in extreme industrial and off-highway environments, allowing users to improve the safety and integrity of their control systems. OEMs can choose from a wide selection of parameters so they can best configure the sensor to suit their needs and achieve maximum performance. They can specify the measurement range and output in a clockwise or anticlockwise direction. For example, one signal can be used in a control function while the other is used for position monitoring or display purposes. The sensor operates from either a 5Vdc regulated or 9-30Vdc unregulated power supply and has an over-voltage protection to 40Vdc. It can be supplied programmed with any one of 341 different angles in the range 0-20 to 0-360 degrees in one degree increments and it has a 12 bit resolution (0.025%) over the selected measuring range. For ease of configuration, SRH280DP is ...


New measuring principle for low cost displacement sensors
 
Micro-Epsilon has developed a completely new displacement measurement principle with its new Magnetic Displacement Sensor (MDS). In contrast to the widely used Hall Effect principle, the MDS is based on a method patented by Micro-Epsilon, which is based on a linear relationship between the position of the magnet and the output signal. As printed coils are used for this measurement principle, the manufacturing method does not depend on semiconductor processes. This makes customer-specific adaptations considerably easier. The sensors have an extremely high basic sensitivity, which enables a very simple and low cost evaluation circuit. With an eddy current sensor as the technological core, very fast, high resolution versions can be achieved. Compared to Hall Effect sensors, much larger measuring ranges (currently 60mm limit) can be achieved. ...
