PRAS20 Magnetic Angle sensor
Absolute magnetic angle sensor up to 360 degrees in a flat housing
• Non-Contact, external magnet
• Only 6 mm thickness
• 0.5...4.5 V ratiometric
|
|
|
The QR angle sensor is designed to measure non contact rotary displacement from 0 to 360 degrees without mechanical stop. A magnet needs to be fitted to the rotating axle and the sensor can be mounted opposite with a maximum 5 mm gap. This gives plenty of room for mechanical tolerances in extreme circumstances. In combination with our robust QUADRO® (PDF) housing you get a accurate sensor that withstands a few knocks. We supply a range of electronic input / output options with 8, 10 or 12-bits resolution to cater for the wide range of applications. Custom design housing with or without integrated magnet are an option.

Magnetic Encoders
As market conditions become increasingly competitive, magnetic encoders are seen as a promising incumbent, offering engineers an encoder solution that is small, robust, yet, priced significantly lower than existing absolute encoders in the market today.
A magnetic encoder typically uses Hall effect or magneto-resistive (MR) effect to sense positional information. Avago's magentic encoder with integrated Hall sensors requires a permanent magnet that is firmly mounted on the rotating shaft of a motor. A magnetic encoder operates on a non-contact basis. Thus, mechanical wear is not a consideration.
Avago’s magnetic encoder solution is high performance, designed for use in a wide range of industries that includes industrial and office automation, as well as, consumer applications. Its typical applications includes test and measurement equipment, surveillance and security, printers, fax machines and copiers, white goods and appliances, cable and satellite dish, toys and games, and much more.

Raychem PESD electrostatic discharge protection devices are designed for I/O port protection in high-speed data transmission applications, PESD devices shunt ESD away from sensitive circuitry in electronic devices. The PESD devices provide exceptionally low capacitance, they perform better than other comparable components in TLP (transmission line pulse) testing, as well as IEC61000-4-2 testing, especially after multiple hits (up to 1000). The devices offer a lower trigger voltage and a lower clamping voltage than typical polymer ESD (electrostatic discharge) devices, resulting in improved protection of sensitive electronic components.

Stand Alone Touchplate Card Reader
The 26SA standalone access control unit provides an effective and inexpensive solution to access control requirements without the need for secondary controllers, software or expensive cable runs when interfaced with a CPEAPE auto gate. A "touch" of the card on the stainless steel face plate allows the 26SA to read the card and grant access to the parking facility.
DESCRIPTION
Self Contained
3500 Card Capacity
Touch Card Slotless Reader
No Control Panels or Secondary Electronics
Easy To Install
Low Power Consumption
Non-Volatile Memory
Timed Anti-Passback (1750 Card Maximum)
SPECIFICATIONS
The 26SA card access control unit utilizes state-of the art electronics in providing a unit that is both inexpensive and fully programmable. The patented slotless reader is protected from weather and vandalism. Simply place the card on the stainless steel touch plate and the card is read instantly and without error. A green light indicates that access has been granted.
Power Requirements:
The 26SA operates from 8 to 24 volts, AC or DC, and consumes less than 200 milliamps.
Outputs:
Latch SPDT Contact, 115V AC or 28V DC, 3A Maximum.
Alarm Shunt SPDT Contact, 115V AC or 28V DC, 2A Maximum.
Tamper SPDT Contact, 115V AC, 2A Maximum (Optional).
Environment:
Ambient Temperature -40°C to 70°C.

Magnetic particle brakes and clutches are of simple design. Due to their size they produce a high torque compared to for instance hysteresis brakes. They are having two rotors (inner and outer) and an air gap between these two rotors where the magnetic particles are dispersed in. An electric current passing through the coil creates a magnetic field, which aligns the magnetic powder into the gap. The higher the current, the more rigid the connection between the inner and outer rotor becomes. The principle is the same for brake, clutch and torque limitor.
Advantages:
Noisless work
Torque directly proportional to current
Torque independant from r.p.m. (starting from 30 min)
Strong design, units are able to be used with steady slipping
High torque range to be controlled (approx 1:50)
Applications:
Braking
Torque control, torque limiting
Tension control at winding, unwinding
Starting clutch operation
Calculated braking and starting
of certain masses and inertias
|
|
|
Eddy Current clutches give torque as a function of RPM. The faster you turn the rotor, the more torque. This means by increasing or decreasing the RPM, you can get infinite torque adjustment. Typically, we rate the clutch with a gain factor (k), which is gram millimeters/rpm or Newton meters/rpm and we design the clutch to have an operating "slip rpm" between 1 and 300 rpm.
|
|
For every application determine the TORQUE, MAXIMUM RPM, and for brakes, the BENDING MOMENT.
Then you can choose the correct shaft or coupling, and various accessories.
All important internal clearances are ground to tolerances of less than .025mm (.001 in). Magnet Assemblies (purple) surround our hysteresis disc (gold). When like poles face each other, they produce maximum magnetic saturation, forcing lines of flux to travel circumferentially through the hysteresis disc. This produces Maximum torque.
When opposite poles face each other, they produce minimum saturation of the hysteresis disc. The lines of flux travel right through the hysteresis disc. Combinations of adjustment angles between these two extremes gives infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.
