Ratings and Specifications

Amplifier Units

✽1. Only for Pre-wired models.

✽2. The following details apply to inputs.

✽3. The communications function and mutual interference prevention function are disabled if detection is set to Super-high-speed mode.

✽4. Mutual interference prevention is enabled if Amplifier Units are connected together. It is also enabled in the same way if E3X-DA-S-series Units

and E3C-LDA-series Units are used together. If power tuning is enabled, mutual interference prevention can be used for up to six units.

✽5. For the E3X-DA@-S (@: 21/51/7/9), the rated sensing distance is approximately 1/2 and the incident level is approximately 1/3 of the normal

levels when ECO mode is enabled.
