Electrostatic Sensor EF-S1

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.
The sensor head is manufactured according to specifications that are complete for use in combination with the optional exclusive controller. Be sure to use it together with the exclusive controller.
Do not touch the sensor head and surrounding parts. If this is not observed, it may cause measurement accuracy to drop.
The metal parts of the sensor head are connected to the 0V line of the exclusive controller power supply, so it should be insulated during use.
Do not use with a plus ground.

Mounting

Sensor head

  • Do not let dust stick to the measurement unit. When dust has adhered to the measurement unit and its surroundings, it may interfere with proper measurement. If dust has adhered to the measuring unit, blow it off using an air blower, etc.
  • When fittings are charged, it affects the measurement accuracy, so use after grounding the fittings. However, the metal part of the case must be insulated.
  • This product has higher sensitivity when used in the measurement distance of 21 to 100 mm 0.827 to 3.937 in compared to when used in the measurement distance of 8 to 20.5 mm 0.315 to 0.807 in, thus it becomes more susceptible to disturbance noise. Check the usage environment before using this product.

Wiring

  • Make sure that the power supply is off while wiring.
  • 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 product, 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.
  • A thin cable of 0.09 mm2 is employed for the sensor head. Note that pulling the cable with force may break the cable.
  • Cannot extend the cable of the sensor head.
  • Make sure that stress is not applied directly to the sensor head cable joint.
  • Extension up to total 10m 32.81 ft is possible with 0.3mm2, or more, cable. However, in order to reduce noise, make the wiring as short as possible.

Others

  • Do not use during the initial transient time (3 sec.) after the power supply is switched on.
  • In order for stable sensing to be carried out, wait for 10 min. after turning on the power before use.
  • Do not use in places where there are strong electric fields apart from those for the object being measured.
  • Do not use in strong magnetic fields.
