Z-Series magnetic marker types for angle sensor applications
Novotechnik, U.S. introduces a selection of four magnetic marker types designed to suit various mounting applications for their RFC- and RFD- Series of touchless rotary angle sensors that provide absolute, rotary position. These two sensor families utilize a magnetic pickup to provide a touchless measurement range of 0° to 360° and makes measurements through air […]
What position is this thing in?
Associated questions could include: Has it moved? In what type of motion? How close is it? While accelerometers, gyroscopes and magnetometers provide inertial measurement units (IMUs) for position sensing in smart phones and other portable products, many other sensing technologies have been used to determine position, long before the smart phone. In industrial applications, more […]
Magneto-inductive sensors as alternative for conventional sensors
Magneto-inductive sensors combine the advantages of both inductive and magnetic sensors. The sensor measures with high dynamics the distance to a magnet, which is fixed at the measurement object. The magnet movement effects a change in the magnetic flow in the sensor element which is detected by the sensor coil. This results in a linear […]
Hollow-Shaft Rotary Encoders
With its ECI 4000/EBI 4000 rotary encoder series, HEIDENHAIN adds to its existing line of inductive position encoders. The modular devices have a 90-mm hollow shaft without an integral bearing and consist of a scanning unit and the scale drum. They have an overall height of only 20 mm. The single-turn version of the ECI 4000 features resolution […]
Magnetometer targets wearable devices with low-noise output
MEMSIC Inc. has announced the availability of its MMC3630KJ, an ultra-small size, BGA package, magnetometer for portable devices. In recent years, the market for MEMS sensors market has grown rapidly and is widely adopted in consumer electronics, industrial control, automotive electronics and other fields. New technology based on motion sensing fusion is playing an increasingly […]
Stainless Steel Housed, Multi-Turn Absolute Encoders
Applications that require withstanding constant shocks and vibrations, high bearing loads, dirt, and temperature fluctuations, dictate special sensor design considerations. Pepperl+Fuchs had these as targets when they designed the CVM42H CANopen Multi-Turn Absolute Encoders. Available with an IP66, IP68, or IP69K environmental rating, the encoders utilize magnetic sampling to deliver 24-bit resolution position value through […]
Encoders Integrate Fault Exclusion Feature
Electrical and electronics play a key role in the capability of many sensors including encoders. However, mechanical problems can undo all the good of the electronics if something goes wrong that can’t be detected. For its RCN absolute encoders, HEIDENHAIN Corporation integrated a Fault Exclusion for Loosening of the Mechanical Connection. Available in both a […]
New Two-Wire Hall-Effect Latch
Allegro MicroSystems, LLC introduces a new two-wire Hall-effect latch with increased magnetic sensitivity. The A1245 latch is produced on the Allegro™ advanced BiCMOS wafer fabrication process. It implements Allegro’s patented high frequency, 4-phase, chopper-stabilization techniques to achieve magnetic stability over its full operating temperature range, -40 to +150ºC. A Hall-effect latch will be in the […]
