Note:
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.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
