Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were an ambient temperature of +23 ℃ +73.4 ℉.

2) To mount the long sensing range type on a magnetic body, such as iron, the enclosed aluminum sheet, or any other aluminum sheet having a minimum size of 30 x 39.5 x t 0.3 mm 1.181 x 1.555 x t 0.012 in (GXL-15HLU type: 30 x 30 x t 0.3 mm 1.181 x 1.181 x t 0.012 in), should be inserted between the sensor and the magnetic body.
However, it is not necessary to use the aluminum sheet when mounting on a non-magnetic body, such as, aluminum or an insulator.

3) The maximum operation distance stands for the maximum distance for which the sensor can detect the standard sensing object.
The stable sensing range stands for the sensing range for which the sensor can stably detect the standard sensing object even if there is an ambient temperature drift and/or supply voltage fluctuation.

4) It is the leakage current when the output is in the OFF state.

5) The maximum load current varies with the ambient temperature.

6) When the cable is extended, the residual voltage becomes larger according to the resistance of the cable.
The residual voltage of 5 m 16.404 ft cable length type increases by +0.1 V.

7) If using the sensor in an environment where cutting oil droplets splatter, the sensor may be deteriorated due to added substances in the oil.
Please check the resistivity of the sensor against the cutting oil you are using beforehand.

8) The bending-resistant cable type (model No. with suffix “-R”) has a 0.15 mm2 (GXL-15 type: 0.2 mm2) bending, oil, heat and cold resistant cabtyre cable, 1 m 3.281 ft long.

  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.]

As the sensing object size becomes smaller than the standard size (iron sheet 15 × 15 × t 1 mm 0.591 × 0.591 × t 0.039 in), the sensing range shortens as shown in the left figures.

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

GXL-8 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. With the attached mounting screw and nut, take care that the thickness of the mounting plate should be 2.3 mm 0.091 in or less.
  • If a screw other than the attached screw is used, make sure to use a M3 truss head screw.
    (Do not use a flat head screw or a pan head screw.)

pic01

GXL-15 type

  • The tightening torque should be 1 N·m or less.
  • To mount the sensor with the optional sensor mounting bracket MS-GXL15, the thru-hole diameter should be ø3.4 mm ø0.134 in.
  • Screw, nut or washers are not supplied.
    Please arrange them separately.
  • To mount the long sensing range type on a magnetic body, such as iron, the enclosed aluminum sheet, or any other aluminum sheet having a minimum size of 30 × 39.5 × t 0.3 mm 1.181 × 1.555 × t 0.012 in (GXL-15HLU type: 30 × 30 × t 0.3 mm 1.181 × 1.181 × t 0.012 in), should be inserted between the sensor and the magnetic body.
    However, it is not necessary to use the aluminum sheet when mounting on a nonmagnetic body, such as, aluminum or an insulator.
  • When mounting the inductive proximity sensor with the optional sensor mounting bracket MS-GXL15-2, if the bracket is mounted close to the sensing part, the bracket itself gets sensed and the operation becomes unstable. Make sure to mount such that the mounting holes of the sensor and those of the mounting bracket are in one horizontal straight line.

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.

Others

  • Do not use during the initial transient time (50 ms) after the power supply is switched on.

Wiring

  • The sensor must be connected to a power supply via a load. If the sensor is connected to a power supply without a load, the short-circuit protection makes the sensor inoperable. (The output stays in the OFF state and the indicator does not light up.) In this case, rectify by connecting the power supply via a load. Now, the sensor becomes operable. Further, take care that if the power supply is connected with reverse polarity without a load, the sensor will get damaged.
    Wiring
  • For series connection (AND circuit) or parallel connection (OR circuit) of sensors, take care of the following.
    マイクロ近接センサ[アンプ内蔵] GXL
  • The residual voltage of the sensor is 3 V. Before connecting a relay at the load, take care of its actuation voltage. (Some 12 V relays may not be usable.)

  • Following work must be done in case of using this product as a CE Marking (European standard EMC Directive)conforming product.

    Ensure that the shield is connected to 0 V.

    Use conditions to comply with CE Marking
