GMW is at Booth 433 of the Sensors Expo and Conference at the McEnery Convention Center in San Jose. The Exhibit area is open 10am to 6pm on Wednesday and 10am to 4pm on Thursday. GMW invites you to register here for complimentary registration to the Keynote Session and Expo Hall or for discounted full conference registration.
From AKM Microelectronics:
- GMW will be demonstrating an implementation of non-contact linear position measurement for application to battery powered tools or controls. A range of about 13mm with about 0.01mm resolution is achieved using a small permanent magnet sliding by an AKM Linear Magnetic Sensor featuring a higher dynamic magnetic field range than Si Hall Sensors. An AKM Micropower Hall Switch powers the position measurement “On” from the sleep state after a preset initial travel.
- We will be showing examples of the AKM PCB Mounting Current Sensors enabling 3kV voltage isolated electric current measurement with full-scale ranges from ±6A to ±180A, frequency response from dc to as high as 1.5MHz and Response Time as short as 1us, 3.3V and 5V rail voltage versions with package sizes as small as 7.9 x 7.6mm. Operating temperature range is from -40°C to as high as 125°C.
Senis is introducing their three component, high field, Hall effect field measurement technology implemented in 0.35mm CMOS circuitry:
- The Senis Three-Component IC with full-scale field ranges Bx, By, Bz selectable from ±0.1T to ±2T in an effective measuring volume of 0.15×0.15×0.01mm is the Field Probe in the Senis M3D-2A-PORT Magnetic field Mapper demonstrating the possibility of high position resolution for magnetic linear and angle encoders and magnetic pattern scanning.
- The SENM3Dx Sensor can be programmed to measure any combination of Bx, By, Bz with analog and digital outputs for selectable field ranges from 5mT to 6T with frequency response from dc to 200kHz. It will be shown with two Sensors in an antiparallel, single component configuration to measure high currents in bus bars or cables in a compact geometry at low cost.
- The SENA2Dx Fast Magnetic Angle Sensor will be mounted in an end-on geometry with respect to a motor shaft to show the capability of better than 0.1 degree angle resolution, time delay of less than 1us and rotation speeds to 200krpm.
Lou Law from GMW will be supporting the AKM Magnetic Sensor range and Sasa Spasic and Thomas Kaltenbacher will be showing the Senis Sensors.
Ian Walker and Ben Hartzell will also be at the GMW Booth. If you are visiting Sensors Expo, please stop by.
