CDX series uses AIR technology to detect masking. To realize a stable performance, CDX series differentiate
between true masking and other masking caused by environmental changes such as dust/dirt adhesion, temperature
changes and direct light by optimizing it's sensitivity. Conventional MW technology can emit an unwanted detection area. The CDX-AM uses double conductive sheilding, which prevents visible lisght disturbance and RFI can also be blocked.
