Amplifier Built-in / U-shaped Micro Photoelectric Sensor[Compact / Cable type] PM-45

Cautions For Use

  • Do not use this product for an application where it directly detects the human body. Otherwise, there is a risk of death or serious injury.
  • When the human body needs to be detected for safety application, use products that conform to the laws and standards related to human body detection for safety application in each country, such as OSHA, ANSI, and IEC.
  • The PM-□45 conforms to the international standard ISO 13849-1 (Category 1, PLc) and can be used as a detection device to indirectly protect the human body.
  • When using the PM-□45 as a part of the safety system, observe the precautions summarized in the “When Using for Safety Applications”. The “When Using for Safety Applications” explains important rules that must be observed to prevent personal injury and property damage when using the product as a part of the safety system. The “When Using for Safety Applications” can be downloaded from the following website.

PM-45 Mounting

Cable extension

  • Cable extension is possible up to an overall length of 100 m 328.084 ft with a 0.3 mm2, or more, cable. However, since a voltage drop shall occur due to the cable extension, ensure that the power supply voltage at the end of the cable attached to the sensor is within the rating.

Cable extension

But, when the overall cable length, including the cable attached to the sensor, is as given below, there is no need to confirm the voltage.

Conductor crosssection
area of extension cable
Total cable length
0.08 to 0.1mm2 Up to 5 m 16.404 ft
0.2mm2 Up to 10 m 32.808 ft
0.3mm2 Up to 20 m 65.617 ft

When using the product as an S-mark compatible product in Korea

  • The power supply cable and output cable connected to the product must be less than 10 m 32.808 ft.

Other

  • This device has been developed / produced for industrial use only.
  • Since the sensor is intended for use inside machines, no special countermeasures have been taken against extraneous light. Take care that extraneous light is not directly incident on the beam receiving section.

  • Do not use during the initial transient time (50 ms) after the power supply is switched on.
  • If the sensor is used in a place having excessive dust, periodically clean the emitting and receiving sections with a dry, soft cloth.
  • If there is a large surge generating equipment, such as, motor, solenoid, electromagnetic valve, etc., in the vicinity of the sensor, use a surge absorber on that equipment. Further, do not run the sensor cables along power lines and use a capacitor between +V and 0 V, if required. Use the sensor after confirming that the surge has been eliminated.
