Note:
1.The response frequency is an average value. Measurement conditions are as follows: standard target, a distance of twice the standard target distance between targets, and a setting distance of half the sensing distance.
2.When using any model at an ambient temperature between -40°C and -25°C and a power voltage between 30 and 32 VDC, use a load current of 100 mA max.,
3.For USA and CANADA : use class 2 circuit only.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
