7E2A
DC 3-wire Models / DC 4-wire (NO+NC)
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.
