*1 The received light intensity may vary somewhat when the sensor head's cable layout is changed, so redo the sensitivity setting when changing the layout. The interference prevention function is affected
somewhat when using multiple units installed adjacent to each other. Fine-tune the sensitivity (increase the setting) for adjacent layouts.
*2 Use a 24 VDC power voltage when using a head light transmitting cable of 3 m or more (PX-H71/H71TZ) or 10 m or more (PX-H72).
*3 When using multiple units connected adjacently, the ambient temperature varies with the conditions below.
2 to 4 Units:-10 to +50°C, 5 to 17 Units:-10 to +45°C.
