Attention

Reed SW. Type

When the piston's magnet approaches the magnetic sensor, the internal reed switch will detect the change of magnetic field and close the contacts.

Solid State Type

When the piston's magnet approaches the magnetic sensor, the internal magneto-resistive element candetect the change of magnetic field and cause a tiny voltage change. Switching output is achieved when this signal is amplified by the operation amplifier circuit in the magnetic sensor.

How to install the Magnetic sensor

END OF STROKE DETECTION

STEP 1 Set the piston to the end of stroke position.

STEP 2 Slide the magnetic sensor forward and keep it close to the cylinder wall. Make a mark at the sensor turn-on point.

STEP 3 Slide the sensor forward continuously until the sensor turns off.

STEP 4 Slide the sensor backward until the sensor turns back on and make a mark.

STEP 5 The intermediate position between the 2 marks will be the most ideal position.

INTERMEDIATE STROKE POSITION

STEP 1 Set the piston to the required position.

STEP 2 Slide the magnetic sensor forward and keep it close to the cylinder wall. Make a mark at the sensor turn-on point.

STEP 3 Slide the sensor forward continuously until the sensor turns off.

STEP 4 Slide the sensor backward until the sensor turns back on and make a mark.

STEP 5 The intermediate position between the 2 marks will be the most ideal position.

ORDERING INFORMATION

CONNECTION METHOD

2 Wire sensor connection

When connecting 2-wire sensors in series (AND), don't exceed more than two sensors due to the internal voltage drop (Typical V drop=2.5 ~ 4V per switch). Excessive Voltage drop will cause non-operation of the load.

  1. When connecting solid state 2-wire sensors in parallel (OR), leakage current will increase and cause improper load operation.
  2. When connecting 2-wire reed sensors in parallel(OR), possible concurrent operation will cause dim LED illumination due to lower current distribution.

3 wire NPN connection

3 wire PNP connection

    1. When using a 2-wire type pressure sensor (KP101/102 & KP10A/10B), please make sure it is connected to a DC power source and a proper resistance load. Otherwise excessive current will damage the sensor permanently.
      Always connect the brown wire to the positive (+), blue wire to the negative (-).
      Permanent damages to the pressure sensor will occur if the connections are reversed.


    1. To improve stability of the pressure sensor and the whole circuit in general, it is recommended to properly ground the DC power source.

    1. When using with inductive load (such as relay or solenoid), please install a flyback diode across the load to remove surge and polarity must be observed or damages to pressure sensor may occur.

    1. Before sensor installation or removal, please make sure the power is OFF and pressure in pipe has been released, released to avoid personal injuries, sensor damage or other losses.
    1. Please separate the power supply of a variable frequency driver or a motor driver from the pressure power supply to avoid noise affect the pressure sensor normal operation.
  1. Do not use corrosive gases or liquids as pressure media.
  1. Do not exceed specification, permanent damage to the sensor may occur.
  2. For reed sensor type sensors, polarity must also be observed for the proper function of LED. Connect the brown wire in series with load to positive (+) and the blue wire to negative (-) of power source. If the polarity is reversed, reed sensor remain functional but LED will remain in "OFF" state.
  3. For solid-state type sensors, polarity must also be observed. Connect brown wire to the positive (+) and the blue to the negative (-) of DC power source. The black wire must connect to the load only. If the black wire is accidentally connected to the power source, permanent damage to the sensor may occur.
  4. An external protection circuit may be required if the magnetic sensor is used with inductive load, such as relay or solenoid. For DC inductive load, attach an external diode parallel to the load and use R-C circuit parallel with AC inductive load as illustrated below.
  5. Keep sensors away from strong magnetic field to prevent malfunctions.
  6. When using reed sensor with capacitive load or if the lead wire length exceed 10-meter, an inductor (560 ~ 1000 μH) or SR-1 ( surge suppressor ) must be installed in series with the sensor to prevent damage (Sticking effect).
