1. ContactTypes
. Form A-Type (normally-open "make" contacts): This type has contactsthat are normally open in the absence aof
  magnetic  field.
. Form B-Type (normally-closed "break" contacts): The contactsof this type of sensorare normally closedin the
  absence a magneticfield.
           of
. Form C-Type (double-throw "break before make" contacts): The normally-closed    contactsof this type of sensoropen
  before the normally-opencontactsare closed.


2. OperatingMethods
  Aleph proximity sensors  detectthe closeness two mechanicalparts by having the sensormountedon one of the parts
                                              of
  and a permanentmagnet,magneticplate or shield plate mountedon the other.Thesemethodsare illustratedbelow. Typical
  applicationsare the detectionof door closures,the detectionof the presence papertrays in copiers,safetyinterlock
                                                                            of
  systems, and the detectionof the "home position" of a mechanicalassembly.

  actuated moving the permanentmagnetin any of the following
          by                                                  ways: horizontal,perpendicular,         pivotal or

4. PhysicalCharacteristics
                                                          into four basic categories:
    We can divide proximity sensors'physicalcharacteristics
.   Operationalcharacteristics
.   Electricalcharacteristics
.   Mechanicalcharacteristics
.   Environmentalcharacteristics

    Operational Gharacteristics
    The major operationalcharacteristic actuating distance.A secondary
                                       is                                factor is differential.
    'ON' distanceis the distanceat which the sensoris activatedas magneticmaterialmoves toward it.
    'OFF' distanceis the distanceat which the sensorchanges  stateas magneticmaterialmoves away from it.
    'DIFFERENTIAL' is the difference between the ON and OFF distances.
    (Nb: Form Btype (NC) sensors   require an actuatingmagneticfield of oppositepolarity from the built-in magnet.)
    REPEATACCURACY The repeataccuracyof a typical sensoris normally within t0.2mm (t0.008 inches).
    See Section3 for the generaloperatingcharacteristics different types of magneticproximity sensors.

    specialfeaturesand considerations.


    ElectricalCharacteristics
    Tracking Frequency:      200 - 300H2
    BounceTime:              Normally less than 0.3 milliseconds
                             If the sensorcontainsa mercury reed switch, there is no bounce.
    On Resistance:           Normally not more than 200 milliohms.
                             This figure reflectsresistanceintrinsic to the connectionarea.Contactresistance  will vary
                             slightly because contactpressure  will change  with the distanceof the actuatingmagnetfrom
                             the sensor.
    ContactBreakdownVoltage: Normally 200 VDC
                             Sometimesas high as 1000 VDC. This refers to the voltage betweenopen contacts.
    Dielectric Strength:     Normally not less than 1500 VDC, measured      acrossthe caseand sensorchargingarea.
    InsulationResistance:    Normally not less than 10 milliohms, measured    acrossthe caseand contacts.


    Mechanical Gharacteristics
    Shock:                       When subjected shock,changes the ON and OFF distances
                                                 to              to                          may occur.Form B-type
                                 contacts may changewhen receiving shocks of over 20 G. Form Atype contacts can
                                 normally withstanda shock of 30 G.
    Vibration:                   Magnetic proximity sensors relatively immune to vibration. However,changes
                                                            are                                              can occur

                                 if acceleration
    TensileStrength:             Typeswith wires using #26AWG wire: 5 kg
                                 Typeswith integral connector:3kg, dependingon connector.


    Environmental Characteristics
              Ranges:
    Temperature                  Plasticcase:-20oCto +70"C
                                 Heavy-dutycase:rangecan be extended.
                                 Internal reed switch: -30'C to +125"C
                                 The sensoritself undergoes  only slight changesdue to temperature variations.The
                                 temperaturecharacteristicsof the actuating permanentmagnet are more important. When
                                 temperature rises,sensitivityof Form A-type sensors (NO) will fall, while sensitivityof
                                 Form B-types(NC) will rise.
    Humidity:                    Excellentimmunity to humidity.
                                 However, prolonged exposure to high-humidity environments will produce a drop in
                                 insulationresistance.
