Development / Design Miniaturization
Miniaturization and design flexibility are essential for product improvement.

Miniaturization is an ongoing challenge for product improvement. Miniaturization of parts is essential to make products smaller. However, miniaturization requires strict mounting and processing accuracy. In addition, there are restrictions on placement due to the positional relationship with surrounding mechanical parts. Dimensional tolerances become more strict, resulting in increased design constraints.
OMRON contributes to the improvement of products and equipment by solving the problems of development and design personnel through the "supply of electronic components with miniaturization and high design flexibility."

Here are electronic components that achieve both "miniaturization" and "high design flexibility."

Why can't it be miniaturized?

  • No small sized parts available that meet specifications ・・・ Go to123
  • No margin for dimensional tolerances ・・・・・・・・・・・・・・・・・・ Go to1
  • Restrictions on movement direction ・・・・・・・・・・・・・・・・・・・・ Go to2
  • Restrictions on mounting direction ・・・・・・・・・・・・・・・・・・・・・ Go to3

1Subminiaturization & absorption of dimensional tolerances

Detected object / Rattling / 2 to 5 mm lineup

The generous groove width allows for the absorption of tolerances such as rattling.


EE-SX Series
Photomicrosensors (SMD Type)

Groove width 2/3/4/5 mm

SMD type realizes subminiaturization.

・Design flexibility
Selectable from a lineup of groove widths from 2 to 5 mm,
depending on the object to be detected.

Product features are featured on the products.

2Switch can be pressed from the side

Conventional switch

Can be pressed from above but not from the side

Direction of dog or cam

D2EW series

Can be pressed from the top or left or right.


D2EW Series
Sealed Ultra Subminiature Basic Switches

Industry’s smallest class*1

・Design flexibility
The mountain-shaped plunger structure expands the direction setting of the cam and dog, reducing restrictions on the mounting position.

Product features are featured on the products.

*1. According to OMRON's research as of January 2023

3Suitable for various installations

Screw mountable from 4 directions

Detection distance is adjustable.

Detection variable range  150mm to 550mm

Diffuse Reflective Sensor

Ultracompact design while capable of long-distance detection.

・Design flexibility
The detection distance can be changed. In addition, screws can be passed through from four directions to accommodate various installations.
