KHS-17A11-6 Medium Hi Power 24VAC PCB Relay 5A Industrial Control Relay

The KHS-17A11-6 Medium Hi Power Relay is a robust PCB-mounted industrial relay designed for reliable switching performance in AC control systems. Featuring a Form 2C (DPDT - Double Pole Double Throw) contact configuration, this relay enables control of two independent circuits, making it suitable for automation systems, industrial machinery, control panels, and general-purpose switching applications.

This relay operates with a 24VAC coil, providing stable actuation in AC-powered control environments. With a coil resistance of 160 , it is engineered for efficient energy usage while maintaining dependable switching performance under continuous operation. The design ensures consistent coil response and long-term reliability in industrial conditions.

The KHS-17A11-6 supports a maximum switching current of 5A, making it suitable for medium-load applications involving both AC and DC circuits. Its electrical rating of 5A at 28VDC or 250VAC allows it to handle a wide range of control tasks, from low-voltage electronics to mains-level switching within rated limits.

Built with silver (Ag) contact material, the relay ensures excellent conductivity, reduced contact resistance, and improved wear resistance over repeated switching cycles. This enhances operational life and ensures stable performance in demanding environments.

With PCB termination, the relay is designed for direct board mounting, allowing compact integration into electronic assemblies and control systems. Its vertical housing format (28 x 22 x 36mm) supports efficient space usage while maintaining mechanical stability on the PCB.

The KHS-17A11-6 is certified to UL, CSA, and TÜV standards, ensuring compliance with international safety and quality requirements. Its reinforced insulation (1.5kV isolation voltage) adds an extra layer of protection, making it suitable for industrial and commercial applications where safety is critical.
