M12 Power K-/S-Coded Push/Pull Connectors

HARTING M12 Power K- and S-Coded Push/Pull Connectors are reliable circular connectors that provide fast and easy connection in high vibration environments. These connectors feature a robust housing and reliable locking system with an audible click indicating a connection. The K- and S-Coded M12 connectors offer 360° shielding, a 630V rating, a 12A current, and ≥100 mating cycle durability within a -40°C to +125°C limiting temperature range. The HARTING M12 Power K- and S-Coded Push/Pull Connectors are ideal for field installations, panel feed-throughs (PFTs) with single wires, and device integration onto a PCB.
