Conditions for the load

  1. The load should not be actuated by the leakage current (0.8 mA) in the OFF state.
  2. The load should be actuated by (supply voltage – 3 V) in the ON state.
  3. The current in the ON state should be between 3 to 70 mA DC
    [In case the current is less than 3 mA, connect a bleeder resistance in parallel to the load so that a current of 3 mA, or more, flows.]

Correlation between sensing object size and sensing range
Correlation between sensing object size and sensing range

As the sensing object size becomes smaller than the standard size (iron sheet 25 × 25 × t 1 mm 0.984 × 0.984 × t 0.039 in), the sensing range shortens as shown in the left figure.

Cautions For Use

  • Never use this product as a sensing device for personnel protection.
  • In case of using sensing devices for personnel protection, use products which meet laws and standards, such as OSHA, ANSI or IEC etc., for personnel protection applicable in each region or country.

Mounting

GL-8U type

  • Make sure to mount with an M3 (length 12 mm 0.472 in or more) truss head screw with a tightening torque of 0.5 N·m or less.
    (Do not use a flat head screw or a pan head screw.)
    GL-8Uタイプ 取り付け

GL-18H/18HL type

  • The tightening torque should be 0.5 N·m or less.
  • To mount the sensor with a nut, the thru-hole diameter should be ø3.4 mm ø0.134 in.
  • Screws, nuts or washers are not supplied. Please arrange them separately.
    GL-18H/18HL type

Influence of surrounding metal

  • When there is a metal near the sensor, keep the minimum separation distance specified below.

    Note: When mounting the GL-18HL□ to an insulator or using the attached sensor mounting bracket, “C” becomes 0 mm 0 in.

    Mutual interference prevention

    • When two or more sensors are installed in parallel or face to face, keep the minimum separation distance specified below to avoid mutual interference.

    Notes:

    1) “I” in the model No. specifies the different frequency type.

    2) Close mounting is possible for up to two sensors. When mounting three sensors or more at an equal spacing, align the model with “I” and the model without “I” alternately.
    The minimum value of dimension “E” should be as given below. GL-18H type: 11 mm 0.433 in

    Sensing range

    • The sensing range is specified for the standard sensing object.
      With a non-ferrous metal, the sensing range is obtained by multiplying with the correction coefficient specified below.
      Further, the sensing range also changes if the sensing object is smaller than the standard sensing object or if the sensing object is plated.

    Wiring

    • Please carry out the wiring carefully since protection circuit against reverse power supply connection is not incorporated. (Excluding GL-8U type)
    • The output does not incorporate a short-circuit protection circuit. Do not connect it directly to a power supply or a capacitive load. (Excluding GL-8U type)
    • Make sure that the power supply is off while wiring.
    • Verify that the supply voltage variation is within the rating.
    • If power is supplied from a commercial switching regulator, ensure that the frame ground (F.G.) terminal of the power supply is connected to an actual ground.
    • In case noise generating equipment (switching regulator, inverter motor, etc.) is used in the vicinity of this sensor, connect the frame ground (F.G.) terminal of the equipment to an actual ground.
    • Do not run the wires together with high-voltage lines or power lines or put them in the same raceway. This can cause malfunction due to induction.

    Others

    • Do not use during the initial transient time (50ms) after the power supply is switched on.
    • Take care that the sensor does not come in direct contact with oil, grease, or organic solvents, such as, thinner, etc.
    • Make sure that the sensing end is not covered with metal dust, scrap or spatter. It will result in malfunction.
