  • If a capacitor of 1 μF or more is connected between 0 V and output or between +V and output, connect a 100 Ω resistor in series as shown below.

pic02

Without the resistor, the short-circuit protection is activated by the charge or discharge current of the capacitor, so that it results in delaying the response whenever the sensor switches. The connected resistor solves this problem.

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

  • The tightening torque should be as given below.。

Mounting with set screw

<Shielded of threaded type>

  • Tighten the set screw on the flat surface of the sensor without applying excessive force. Make sure to use a set screw with a cup-point end.

Note: The protrusion should be kept C (mm in) or more to avoid reduction of sensing range.

  • To fasten GX-3S□ and GX-4S□, use a M3 or less set screw and tighten it from a direction perpendicular to the operation indicator.
    小型近接センサ[アンプ内蔵] GX(終了品)
  • When using the C bracket, place it on the sensor at a distance of 3 mm 0.118 in or more from the sensor end.
    小型近接センサ[アンプ内蔵] GX(終了品)
  • To fasten the non-shielded threaded type, tighten the set screw on the flat surface of the sensor.

Mounting with nut

  • Note that the maximum tightening torque differs according to the location of the nuts.

Note: Mount such that the nuts do not protrude from the threaded portion.

  • The root truncation of the threads with GX-8M□ and GX-8ML□ is shallow owing to strengthening of the sensors against tightening.
    When tapped hole on equipment to fix the sensors, the prepared hole must be ø7.2 mm ø0.283 in or more.
