Product Overview
The Omron D4B-4116N lives in the D4B-N product family but belongs to the general-purpose subgroup, not the safety subgroup. manufactured by Omron Corporation. Hengyixin Automation stocks this limit switch in Xiamen and ships within 3-5 business days; safety-rated components ship with a batch-trace certificate.
It uses the same heavy-duty aluminum die-cast housing, M20 conduit, IP67 sealing, and -40 to +80 °C operating range as the safety-rated D4B-4111N, but it does not carry the certified direct-opening mechanism. It is the right pick for general machine position feedback where EN ISO 13849 or EN 60947-5-1 safety certification is not required.
The D4B-4116N ships from Xiamen with full datasheet documentation. The A600 rating is 10 A carry, 7,200 VA make, 720 VA break — well above the 4 A to 5 A the switch will see in typical control duty.
Key Features
- Rated 10 A resistive at 250 VAC; A600 (UL/CSA)
- M20 conduit entry
- 1NC / 1NO snap-action contact
- Mechanical life 30,000,000 operations min
- SKU: D4B-4116N
- Series: D4B-N (general-purpose limit switch, metal body)
Best-Fit Applications
- Position feedback on conveyor transfer arms
- General position sensing on industrial machinery
- Full-open / full-close signals on loading-dock doors
Buying Checklist
- Use an M20 cable gland rated for the environment (IP67 minimum).
- Choose D4B-2116N if your cabinet uses G1/2 / PF1/2 conduit instead of M20.
- Choose D4B-4116N for non-safety limit duty in metal-body harsh environments.

FAQ for D4B-4116N
Is D4B-4116N a safety limit switch?
No. The 4116 code is in the D4B-N general-purpose subgroup. It does NOT carry the certified direct-opening mechanism required for safety guard-door interlocks. For Cat 1 / PL c and higher safety applications, choose D4B-4111N (resin roller lever) or D4B-4115N (stainless roller lever) — both of which carry the certified DOM.
What is the difference between D4B-4116N and D4B-4117N?
D4B-4116N uses an adjustable roller lever — best for cam and angled approach. D4B-4117N uses an adjustable rod lever — best for linear push applications where you cannot fit a cam profile. The contacts, body, and ratings are otherwise identical.
What conduit size does D4B-4116N take?
M20. The G1/2 / PF1/2 equivalent is sold as D4B-2116N. Use an M20 cable gland rated at least IP67 for the application environment.
