They are suitable for rotary speed sensing, for detection of gearwheels and for standstill control. Areas of use can be heavy construction engines, rail vehicles, large diesel engines and turbines The magnetoresistive sensors(MRS)work like a magnetic Wheatstone bridge. They react to all ferromagnetic materials. The tooth or gap of a gearwheel, which passed the active area of the sensor, have a different influence on the magnetic field. This results in a change of the magnet-field dependent resistor. This change of the magnetic field is transformed to an electrical voltage-bridge, which then is filtered and prepared. The output signal is a voltage, which corresponds to the magnetfield change We have two different series → Series300 -s 3-wire pnp or nen 2-wire → Series350 4-wire pne or nen 4-wire PNP with dephased output signal with detection of direction of rotation The components of the MrS are mounted in plastic or metal casings and encapsulated with epoxy casting resin The plastics used for the housings are E PA(polyamide)6.6 glass-fibre reinforced E PEEK (polyetheretherketone) And the metal housings are A VA stainless-steel, material No. 1. 4404 or No. 1.4305 E MS brass/chrome or nickel-plated Since the active area is made from a block material the degree of protection IP 68 is achieved on the front e end Only pre-tested electronic components, proven integrated circuits and hybrid circuits are used and pro -5 duced with SMT. The standard constant ambient temperature permitted is dependent on the model from -40 up to+125 C(see data sheet) With contactless detection no physical actuating force is required for operation. There is no contact bounce, t no sensor wear, no maintenance and the service lite is independent of the switching frequency MRS can be used in machines, systems and vehicles for contactless detection, for monitoring and positioning, as a pulse generator for counting tasks and speed measurements, and for many other applications (for application examples see page 8) RechNerIndustrie-elektronikGmbh.Gaulsstralse8-10.d-68623LampertheimTel.+49(0)62065007-0.fax+9(0)62065007-20.emailinto(arechner-sensors.de.www.recmer-sansors.de SENSORS Wiring of the MRs should be routed separately or screened from heavy conductor lines, as in extreme cases inductive peak voltages can destroy the sensors despite the integrated protective circuit. Screened cable or twisted lines are recommended, especially for longer cable runs> 5 m Direct control of electric light bulbs is to be avoided, because during the switch-on moment cold current is many times the rated current and can destroy the output stage of the sensor Units with strong local field power, e. g. high power walkie-talkies, or noise sources in the lower fre quency range, e.g. long, middle or short wave transmitters should not be operated close to the sensors or additional measures have to be taken in order to eliminate the maloperation 2-and 3-wire sensors with binary output can be used in series or parallel connection, similar to mechanical contacts. It is important to note the type-typical voltage drop and the residual voltage Ua, that must be multiplied, for series connection, in accordance with the number of sensors Series connection Parallel connection 2 wire DC 四刚 3 wire DC NPN 3 wire DC PnP o030c059 人z RecHnErIndustrie-elekIronkGmbh.gaUllstrAlse8-10.D-68623lAmperheim.Tel.+-19(0)62055007-0.Fax-49(062065007-20.emailino(rechner-sensors.ce.www.rechner-sensors.de5 SENSORS The material and version-dependent maximum torque should be taken into consideration when mounting in order to prevent damage to the threaded sleeves.

Depending on that the length of the threaded block for screwing in proximity sensors should not exceed the following dimensions. In the case of larger threaded blocks we recommend drilling a blind hole in order to adhere to the maximum screw-in length Thread M5×05 Max 1 M12x1 M18×1M22×15M30×15M32x15 Screw-in length 3 mm 6 mm 8 12 mm 12 mm 12 mm 12 mm m ax ADJUSTMENT Speed sensing is possible with gearwheels down to module 1 at a maximum switching frequency of 15 KHZ For detecting rotary speed/direction of rotation magnetoresistive sensors(MRS)must be mounted radially with respect to the direction of motion and with their marking set vertically to it The dependence of the modul of the detected gearwheel on the mounting distance and the maximum detecting frequency is as follows: Distance [mm] Module 4 Module 2 2.5 2 Module 1 0,5 Example: MRS-300-M18.0 100 10000 Frequence [Hz] 6 RECHNER Industis-Elekaronk GmbH, Gaulstalke 8-10 D 68623 Lampertheim Tel, +19(0)62 06 50 07-D Fax +19(0)62 06 50 07-20 email intorechner sensors de wmrecnsr-segnsorsde SENSORS TECHNICAL TERMS Unless otherwise specified technical data is as follows: +24C, U.= 24 V dC Operating sensing distance /S Within the operating sensing distance the sensor operates reliably taking in to account all the possible tolerances, t lies between 0 and 0.81x S Power up time delay The time the sensor needs to be ready for operation after connecting the operating voltage. It is in the milliseconds range lousing materials The application of the housing materials used is based on the technical specifications of the material and of the manufacturer. The customer is responsible for checking in each case that the housing material is suitable for the application, even though RECHNER Sensors have far-reaching application experience concerning the use of different housing materials Cable For the standard models pvc- or Pur-cable are used. one has to take into consideration that the cable should not be moved with ambient temperatures below -5C. Pvc is not suitable for use in applications with oil-based liquids or with UV-radiation. PUR is not suitable for continuous contact with water. For special application areas silicone or PTFE cables are available Nominal sensing distance /s The characteristic value of a sensor, without consideration of production tolerances and variations due to temperature and voltages. Reference gearwheel module 4, 1000 Hz Real sensing distance /S The sensing distance determined at +20C and rated voltage. Here the series variance is taken into consideration. Variation max. 10 %o Series-and paralle/ connection It is possible to connect the sensors in series or parallel. When considering this it must be taken into account that the voltage drops are added for series connection and the residual voltages for parallel connection. Under these circumstances it is advisable to operate a maximum of three sensors in a corresponding circuit Frequency of operating cycles The maximum damping and un-damping cycles of the proximity sensor within one second.
