Description

The CKSF-03 is part of ILME’s CKS series, which is designed for small rectangular connectors (21.21 mm). This particular insert is the female version with 4 contacts, making it suitable for low- to medium-power connections in industrial environments.

When combined with appropriate housings (such as CKA or CKAX series), the CKSF-03 can achieve IP66/IP67/IP69 protection, ensuring resistance to dust, water jets, immersion, and high-pressure cleaning. Its compact size makes it ideal for applications where space is limited but reliability is essential.

Typical Applications

• Factory automation systems requiring compact connectors
• Robotics and assembly lines with limited installation space
• Outdoor machinery exposed to dust, rain, or washdowns
• Transport and marine equipment needing rugged, certified connectors
