High-precision Optical Switch Optical System Achieves 1-μm Operating Position Repeatability in this 4-way Switch • No-contact structure for high reliability. • Ceramic materials in measuring part for superior resistance to abrasion. • Two different output types (PNP and NPN) available. • Less abrasion and damage of mechanical contacts compared to switches with contacts, reducing fluctuation in the output. • More compact than previous OMRON models: 40% less mass, 15% lighter across the operating width. Be sure to read Safety Precautions on page 4 and Safety Precautions for All Limit Switches.

Durability values are calculated at an operating temperature of +5°C to +35°C, and an operating humidity of 30% to 70%RH. Contact your OMRON sales representative for more detailed information on other operating environments. *2. Measurements were conducted repeatedly at the same point. The value is 1 μm max. for 200 measurements. For other conditions in detail, contact your OMRON sales representative. *3. The ambient operating temperature varies depending on the current. Refer to the following Engineering Data.
