Product details

Ident & Fit

The 5SJ4318-7HG41: This is a current-production part. No last-time-buy or phase-out notice applies — specify it into your BOM with confidence.

DIN Rail & Panel Integration

Overall dimensions: 54 mm wide × 110 mm high × 70 mm deep. Any mounting position works; installation depth matches the overall depth. Combined terminals top and bottom ease wiring in tight cabinets. Terminal tightening torque specified at 3.5 N·m for copper conductors at 60/75 °C.

IP20 with connected conductors, IP40 in the handle area — no sealed enclosure needed for basic dust protection. Sealable design (lockable handle) supports tamper-proof installations. Suitable for environment B (immunity to interference not applicable).

Same part, different passport — if you see this at a discount from another region, the internal construction is identical. Our cross-border sourcing verifies provenance to match your local compliance requirements.
