*1. These are the available sensing distances at an ambient temperature range between 0°C and 45°C.
*2. This is the half-value angle obtainable at a signal of –6 dB.
*3. The enclosure rating indicates the degree of protection of the case, which will depend on the operating condition.
*4. The response frequencies are values obtained with the E4B used for detecting a rotating propeller-shaped disc as
       shown on the right.
