* The ambient temperature range during operation for connector models depends on the model. For the E3Z-T66/T86/R66/R86, the range is −40°C to 55°C. For the E3Z-D66/D86/D67/D87, the range is −30°C to 55°C. For other connector models, the range is −25°C to −55°C.
The sensing distance for Retro-reflective Models (E3Z-R66/R86) between −40°C to −25°C, however, will be as follows (not the values in the table):
With E39-R1S: 3 m (100 mm), With E39-R1: 2 m (100 mm).
Also, use the XS3F-M42[]-4[][]-L Sensor I/O Connector (PUR cable) for applications between −25°C to −40°C. (Refer to Catalog.)
