About Mitsubishi S-K65 Contactor

A contactor is an electrical device which is used for switching an electrical circuit on or off. ... These contacts are in most cases normally open and provide operating power to the load when the contactor coil is energized. Contactors are most commonly used for controlling electric motors

Durable Design for Industrial Environments

The Mitsubishi S-K65 contactor is built to withstand challenging environments. Its IP20-rated enclosure, UL94 V-0 flammability rating, and thermoplastic insulation ensure safety in harsh settings. Even under high-vibration (5 g, 10-55 Hz) or shock (10 g) conditions, it maintains stable operation. Its robust 1.4 kg frame is crafted to last, making it a trusted component in factories and industrial setups.

Precision Switching Made Efficient

Equipped with silver alloy contacts, the S-K65 offers reliable performance with both 2NO and 2NC auxiliary contacts, enabling flexible integration. With a low coil power requirement-86 VA (AC) or 20 W (DC)-it keeps energy consumption in check. The contactor supports standard 50/60 Hz frequencies and handles up to 690V AC, making it suitable for a broad range of industrial applications.
