Reduce Bypassing Risk With Cost-Effective Safety Door Switches


November 26, 2021

Safety device tampering puts operators at risk and reduces a machine’s performance level. However, it can be challenging to find tamper-proof solutions that are versatile, cost-effective and user-friendly.

The Omron D41 RFID-monitored door switches minimize defeat possibilities while simplifying the design process with a single product family that covers all needs. Both non-contact and guard-locking options are available.

Benefits of the D41 Series

To reduce accident rates, many companies are adopting the EN ISO 14119 standard for interlocking device selection. The Omron D41 Series is a cost-effective way to meet the principles of this standard.

Minimizes Defeat Possibilities

The D41 Series offers non-contact and guard-locking options to help prevent bypassing and meet the highest level of protection for workers.

Reduces Total Cost of Ownership

The D41 Series prevents unnecessary losses and reduces MRO investments thanks to its versatility as a single product family.

Easy to Install and Troubleshoot

LED indicators and user-friendly diagnostic outputs simplify troubleshooting and maximize flexibility for future expansions.

Omron makes safety easy

The D41 Series is a flexible solution that protects operators requiring partial or full body access to machinery in various applications across different industries.

All models offer quick automatic pairing that helps reduce commissioning time, along with three-color LED indicators and diagnostic outputs that ensure the highest level of protection according to ISO 14119.

Key features include:

  •    –   Individual coding, single or multiple teaching type
  •    –   Three-color LED indicators and diagnostic output
  •    –   Protection class IP66, IP67
  •    –   Up to 31 devices connected in series
  •    –   Complies with ISO 14119 (Type 4/High Coded), ISO 13849-1 (PLe)

D41 Series


Non-contact interlock with three different actuator types to save space, symmetrical design for left and right mounting, and a long detection range that supports approach direction from front or side.


Guard lock interlock with hygienic design prevents accumulation of water, food and dust. IP69 and ECOLAB certified, D41L supports three actuating directions and mounts on left- and right-hinge doors.


Guard lock interlock with an integrated door handle offers an ergonomic actuator and reduces design efforts. Models with emergency exit units ensure people can exit, even if the power is disrupted.
