Miniature SMD photomicrosensor for 3D printers

Omron Electronic Components Europe has launched a new, extremely compact reflective photomicrosensor (PMS) with a sensing distance of three to four millimetres, 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 3-4mm 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 new Omron EE-SY1201 reflective PMS is just 3x4x2mm – yet offers a peak sensing distance of 3mm. 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 0.5mm, Omron offers the EE-SY1200.
