*1 The repeat accuracy and temperature characteristic are for a standard sensing object positioned midway through the
      rated sensing distance.
*2 A sudden temperature rise even within the rated temperature range may degrade characteristics.
*3 For the Sensor Head only without the preamplifier (−10 to 60°C). With no icing or condensation.
*4 Do not operate in areas exposed to water vapor because the enclosure is not waterproof.

Switchable between single edge and double edge detection mode
Single edge: Can be set to 300 μs, 500 μs, 1 ms, 10 ms, or 100 ms
Double edge: Can be set to 500 μs, 1 ms, 2 ms, 20 ms, or 200 ms.
Timer
function
Select from OFF-delay, ON-delay, or one-shot timer.
1 ms to 5 s (1 to 20 ms set in 1-ms increments, 20 to 200 ms set in 10-ms increments,
200 ms to 1 s set in 100-ms increments, and 1 to 5 s set in 1 s-increments)
Zero-reset Negative values can be displayed.
Zero-reset is accompanied by a change of detection distance.
After zero-reset, some threshold level may also cause a change of the indication by
influence of other settings.
Initial reset Settings can be returned to defaults as required.
