Measuring just 3- x 4- x 2-mm, the photomicrosensor is ideal for applications such as for 3D printers, factory automation and industrial systems.

Omron Electronic Components Europe has launched a compact reflective photomicrosensor (PMS) with a sensing distance of 3- to 4-mm, plugging a gap in the market for an SMD device addressing applications such as 3D printers, mini printers, e-locks and factory automation equipment.

Gabriele Fulco, Product Marketing Manager for Sensors at Omron, said, “With increasing pressure on system size, there is a definite market trend to move from leaded PMS solutions to SMD, but there is a real need for a miniature device with a mid-range 3- to 4-mm sensing distance. Our new device achieves a comparatively long sensing distance within a compact form factor as a result of its built in lens.”

The Omron EE-SY1201 reflective PMS is just 3- x 4- x 2-mm, and yet offers a peak sensing distance of 3 mm. Typical applications include paper pass detection in mini-printers, pin or cylinder rotation in e-locks, media pass detection in cutting machines and filament rotation in 3D printers. Other uses include factory automation equipment and industrial cameras. For applications requiring a shorter sensing distance of just 0.5 mm, Omron offers the EE-SY1200.


The latest Omron EE-SY1201 reflective PMS offers a peak sensing distance of 3 mm.
