The Mitsubishi Electric UT-AX2 2A auxiliary contact block adds two normally open contacts to S‑T and SR‑T contactors and relays, providing dependable status signaling, interlocking, and flexible expansion of control circuits in industrial automation. Its compact front clip-on design enables fast integration in control panels, MCCs, and OEM machinery without reworking the base device.

Engineered for panel builders and maintenance teams, the UT-AX2 2A uses a slim 18.5 mm × 45 mm × 30 mm form factor to preserve cabinet space while delivering clean contact outputs for PLC input mapping and indication. Front clip-on mounting simplifies assembly and retrofit tasks, and compliance with CE, UL/cUL, and UKCA—as well as RoHS—supports global standards and procurement requirements.

Whether used for auxiliary signaling on motor starters, interlocks on safety-related circuits under system-level design, or general expansion of control logic around S‑T/SR‑T devices, this accessory delivers reliable performance with minimal installation time, and it is backed by a 1-year warranty for added peace of mind.
