Cable Lengths for Sensor-Amplifier Unit Combinations
Standard Models
Note: The standard cable length is 3 m. Models with 5-m or 10-m are manufactured upon order.
* Refer to page 14 for the operation of cable length switching.
Heat-resistant Models
Note: The standard cable length is 3 m. Models with 5-m are manufactured upon order.
Self-diagnostic Function
The self-diagnostic output transistor will turn ON in the following cases. (The output will turn ON for any of these conditions individually.)
(1) Sensor open circuit: Transistor will turn ON the instance there is an open circuit for the Sensor (including the cable).
Sensor Open Circuit
(2) Detection:
(3) No detection: The output will turn ON if a sensing object is within 100% to 107% of the sensing distance continuously for 0.3 s or longer (e.g.,
