ELTRON offers DOLD KO 4030 series plastic enclosures designed for industrial devices and automation systems where reliability and convenient installation are crucial. Their design allows them to be used in both low-current applications and where high-current terminals are required.
KO 4030 enclosures are available in widths from 22.5 mm to 90 mm, heights of 84 mm and depths of 118 mm. Depending on the model, the enclosures can accommodate 6 to 56 connection terminals, including signal and high-current terminals. Thanks to their modular design with removable connector blocks, PCB boards can be quickly connected, which greatly facilitates integration with internal electronics.
The enclosures are available with 3-, 4- or 7-pole connector blocks and optionally in a blanking version. Importantly, many models offer the option of replacing the front panel, which further increases their design flexibility.
DOLD KO 4030 is also a solution that complies with the requirements of the EExi standard according to DIN EN 50 020, making it suitable for use in environments with an increased risk of explosion.
The ELTRON range includes the most popular variants, such as:
