Product Overview
The Omron D4N-112G is a D4N-series safety limit switch with an adjustable roller lever It is manufactured by Omron Corporation. Hengyixin Automation ships this limit switch from our Xiamen warehouse with a 30-day DOA return window and a datasheet PDF included in the box.
The switch has one NC and one NO snap-action contact with gold-clad 3 micron plating for both standard and micro loads. The actuator is a form-lock metal lever with a resin roller, adjustable through 90 degrees of lever swing.
For a compact safety limit switch, use the D4NS-1AF. Key specs: Contact Form 1NC / 1NO, snap-action; Contact Material Gold-clad silver, 3 micron; Actuator Adjustable roller lever, form-lock, metal lever, resin roller; Rated Load (Resistive) 10 A at 250 VAC / 30 VDC; Rated Load (Inductive) 3 A at 250 VAC (cos phi = 0.4); Connection Terminal block, Pg13.5 conduit, bottom entry; Mechanical Life 15 million operations min; Electrical Life 500,000 operations min at rated load.
Key Features
- D4N-series safety limit switch, plastic housing, double insulation
- Adjustable roller lever, form-lock metal lever, resin roller
- 1NC / 1NO snap-action, gold-clad 3 micron contacts, direct-opening
- Pg13.5 conduit, terminal block wiring, IP67, -30 to 70 degC
- SKU: D4N-112G
- Series: Omron D4N-series safety limit switch (plastic housing)
Best-Fit Applications
- Guard-door interlock on a packaging cell where the snap-action 1NC/1NO pair feeds a G9SA safety relay and the direct-opening NC meets EN ISO 14119
- End-of-stroke feedback on a pneumatic gate where the adjustable roller lever matches the existing bracket without machining
- Spare drop-in on a machine retrofit where the existing D4N-112G failed and the Pg13.5 conduit and lever angle carry over
Buying Checklist
- Pick the D4N-112G for a 1NC/1NO snap-action safety limit switch with an adjustable roller lever on the D4N plastic body.
- Pick the D4NA-4122 instead when the application needs a heavy-duty safety limit switch in a metal housing.
- Pick the D4NS-1AF instead when the panel needs a compact safety limit switch with M12 connector wiring.

FAQ for D4N-112G
Is the D4N-112G certified for safety use?
Yes. The D4N-112G carries UL, CSA, TUV (EN 60947-5-1) and CCC approvals. The NC contact has a direct-opening mechanism that mechanically forces the contact open if the mechanism fails.
What is the difference between the 112G and the 1120?
The 112G is the gold-clad version (3 micron) for micro-load reliability. The 1120 is the standard version without gold cladding, used for plain 10 A resistive loads.
Can the D4N-112G lever be rotated?
Yes. The head rotates through 90 degrees in either direction. Loosen the four head screws, rotate to the new position, and re-tighten. The roller can also be inverted on the lever.
