Omron Actuator for Use with D41D Series Switch

Omron D41D Series Actuator, Plastic, For D41D Series Switch - D41D-A2

This actuator is a flat plastic accessory designed to operate with a high-coded non-contact safety door switch in automated machinery. It provides a low-profile actuation surface for acrylic or narrow guard doors and is intended for use where tamper-resistant detection and a Compact form factor are required within enclosed machine spaces.

Features & Benefits

• Flat profile enables discreet mounting in tight spaces
  Thermoplastic PBT head resists mechanical wear and contamination
  Countersunk M5 mounting for secure flush installation
  Compatible with high-coded sensor pairing to prevent misidentification
  Supports lateral actuation with reduced clearance tolerance

**Applications**

• Suitable for detecting acrylic guard doors in production cells
  Ideal for narrow sliding doors in packaging machinery
  Used with limit-switch style safety inputs on machine guards
  Can be employed where low-profile actuator aesthetics are required

What material is used for the actuator housing and why is it chosen?

The head is MADE from thermoplastic PBT to provide mechanical durability while limiting contamination build-up in machine interiors.

How is the actuator mounted to an acrylic door to ensure correct alignment?

It uses two M5 countersunk screws for flush fixing, which helps maintain axial alignment with the sensor’s Active area.

Can the actuator be used where lateral actuation is expected?

Yes
it is designed to permit lateral approaches from the specified sensor side, though operating distances are reduced for lateral actuation.
