The AJ product series refers to FMCW FM continuous wave (FMCW) radar products operating at 76-81 GHz and supporting four-wire and two-wire applications. Several models, the maximum product range can reach 120m, the blind spot can reach 8cm. Since it operates at a higher frequency, the wavelength is shorter, so it is especially suitable for solid applications, through the lens emission to receive electromagnetic waves in operation, under high dust, harsh temperatures (+ 200 °C) has unique advantages. The tools provide fastening of flanges or threads, making the installation convenient and simple. 1. Millimeter range radar, measurement accuracy up to ±2 mm, minimum blind spot measurement of 0.05 m. 2.Smaller antenna sizes meet more measurements of working conditions. 3.Various lens antennas, smaller transmission angle, more concentrated energy, the echo signal is stronger, the same industrial and mineral conditions, compared with other radar products have higher reliability. It has greater permeability and can also be used normally for adhesion and condensation. The dynamic range of the signals is larger, and the measurements of the medium with a low dielectric constant are more stable. 6. In different measurement modes, the response time of the radar in the fast measurement mode is less than 1C.
