Model : PM-K45
 

---

Features :
 

• Sensor unit complies with ISO 13849-1^*1 Category 1 PLc^*2.

• Three protection circuits standard on all models

  • Reverse supply polarity protection circuit

  • Reverse output polarity protection circuit

  • Output short-circuit protection circuit
     

• Industry’s first! IP64 rating
   

• Ample beam emitting / receiving distance of 6 mm 0.236 in
   

• Beam marks for easy adjustment

  • The upper-limit and lower-limit positions of beam can be visually confirmed from the front, back, right and left sides of the sensor unit. This allows easy adjustment of the position of sensing object.

• Large and easy to see
   

 

• Multi-angle operation indicator

  • The large operation indicator (orange) lights up when the beam enters. The indicator is easy to see from above and from the sides.
     

• Compact size

• All models easy to mount with M3 screws
   

• Resistant to vibrations and impacts

  • The sections where stress concentrates, such as the connecting section of the cable and internal circuit, are covered with a resin. This helps prevent malfunctions caused by vibrations and impacts.
