ENS22 ANGULAR SENSOR DIGITAL (SSI SPI) ENS22B ENS22F ENS22K

Transcription

1 ENS22 The sensors of the ENS22 series use the magnetic technology to measure a rotation angle. The housing diameter is 22 mm. ANGULAR SENSOR DIGITAL (SSI SPI) The axis pull a magnet. The position of the magnetic field is measure by an HALL effect sensor. The absolute angular position is transmit to one of the serial bus available (SPI & SSI). There are 3 different types of fixations which share common characteristics: Threaded bushing : ENS22B Fixing lugs : ENS22F Floating magnet : ENS22K The plastic housing allow to reduce the purchase price, but it is also available with a metallic housing (MAB22 series).

Example: Standard Electronics With Options ENS22B SSI OCW360 N LT A30 CV0.1 Digital sensor, M9 bushing, 6 mm shaft,12 bits, supply 5V, SSI interface, without stop, zero point orientation, shaft length 30 mm, cable length 0,1m Example: Standard Electronics With Options ENS22B 2 X 14 05SPI OCW360/ CCW360 Digital sensor, M9 bushing, 6 mm shaft, redundant version, resolution 14 bit, SPI interface, output1: CW on 360, output 2: CCW on 360 N P LT MT HT D A.. CV.. The meaning of CWxx is arising signal level if you turn the shaft in clockwise direction (view on shaft top). The mechanical zero point is adjusted when the shaft flattening is in direction of the anti rotation pin (bushing version) or with the zero score (flange version). At the base type without stop there is no alignment between electrical and mechanical angle. The option N assigns the electrical zero position (minimum signal level) to the mechanical zero position. You also can specify an offset value (please refer to the standard option E2). At the base types with mechanical stops the electrical zero position is on the CCW stop. That means the signal is rising from the minimum level if you turn the shaft in CW direction. When the shaft flattening is in direction of the anti rotation pin, the signal level is at 50% of full scale. The option D (sealing ring) AND the polymer sleeve bearing are available only on special request.

The electrical zero point can be aligned to the mechanical zero point. Nevertheless the zero point can be programmed at any offset according to customer requirement. Offset 0 = Standard option N Rotational direction The standard direction of rotation is clockwise (CW). It is also possible with this option to change the direction from clockwise (CW) to counter-clockwise (CCW) 2-Channel-Output This is made up of a Hall sensor Chip consisting of 2 galvanically separated sensing elements. One magnet provides magnetic field simultaneously for both elements. Channel 2 can also be programmed completely different than channel 1. ES1 ES2 ES3 SPI Interface

10 Preferably miccrocontrollers with SPI interface (Serial-Peripheral-Interface) have the best performance. But also each other miccroprocessor with an open drain I/o CAN BE USED; The communication protocol is very easy and there are just 3 signal wires: >SS...Slave-Select, >SCLK...Clock, >MOSI-MISO..Dataline The bidirectional data transmission at the EcoTurn SPI series is done only over one I/O-port because master and slave are using the line alternatively in a dedicated sequence as follows: -Master: 2 Startbytes (AAh and FFh) -Slave (ecoturn): Two data bytes followed by two inverted databytes -4 bytes no activity from master and slave (Ffh) The following schematic shows the sequence. Please note that the 8 clock cycles for one byte is abstracted by a single clock symbol. The signals MOSI and MISO are transmitted over a single wire (according to the wiring diagram above). For further details please have a look in the internet: (datasheet IC-MH.) SSI interface The SSI-Interface is wide spread in industrial applications with absolute angle sensors. There are a lot of programmable logic controls (PLC) or other peripheral appliances like counters available than can be easily configured for this communication.

11 Furthermore this interface is very insensitive against electromagnetic interferences because of the differential signals that should be transmitted via twisted pair leads.
