SICK CDB420-001 Connection Box Module

The SICK CDB420-001 Connection Box Module is a compact interface that centralizes power, wiring, and external connectivity for a SICK CLV490 1D/2D barcode scanner. It is designed to connect one CLV490 to a host or to a SICK CAN scanner network, while providing peripheral distribution and a dedicated power path. The module is powered from a DC 10–30 V supply (SELV/PELV per IEC 60364-4-41) and furnishes a D-Sub 15‑pin high‑density socket plus a 9‑pin connector for essential signaling. For field wiring, CDB420-001 provides four cable glands (Ø 4.5–10 mm) and supports screw terminals for 0.14–2.5 mm² conductors as well as spring terminals for 0.14–1 mm² conductors. Five indicator LEDs convey status at a glance. An AUX port enables PC connectivity via a three‑wire RS‑232 null modem link to run the CLV-Setup driver for configuration. The part is identified as CDB420-001 (Nr. 1023885) and is part of a family that includes variants such as CDB420-101, which adds CAN bus interfaces via an additional 5‑pin M12 plug and socket for CAN, and CDB420-201 with extra gland entries. In all cases, the CDB420 family serves to couple a scanner to a host, a CAN network, and peripheral devices, while consolidating power input and wiring into a single, centralized module.
