These Optical Sensors provide a compact, low-cost method to detect workpieces. Many models are available, including Transmissive Sensors (slotted type), Reflective Sensors and Actuator Types, all available with different mounting methods (SMD, Through-Hole, Pre-Wired, Connector, Snap-in, Screw mount).

A Photomicrosensor (PMS) is a small optical switch that can detect not only the presence or the absence of an object, but also its position, the size, the speed, the passage or the movement direction of that object. PMS works with LED, so it need very low current to operate (30mA typ.), it has very fast operating speed (4us typ.), high sensing accuracy (±0.25mm and ±0.01mm as repeatability), high operating frequency (up to 3000ops/sec), long durability (100.000 hours), and it's a non-contact sensing product.

Main categories are Transmissive type (where an object is detected when interrupting the beam of light in the PMS slot moving from the emitter to the detector) and Reflective type (where an object is detected when it reflects the beam of light from the emitter to the detector), but also other models are available.
