Proximity/Occupancy Sensors - Finished Units

Proximity Occupancy Sensors Finished Units are complete, ready-to-install sensor modules that detect the presence or absence of people in a space and trigger a response, usually switching a light, an HVAC zone, or a security circuit. Unlike raw sensing components, these are housed, calibrated, and often pre-wired for direct integration into commercial or residential systems. The category covers a wide spread of technologies. Passive infrared (PIR) units are the most common and work by detecting heat movement across a lens. Ultrasonic models emit high-frequency sound waves and measure the echo shift, which makes them better at picking up small movements around corners or behind partitions. Dual-technology units combine both to reduce false triggers, though they cost more and are typically specified for larger commercial installations. Microwave and camera-based variants exist too, but they are less common in standard distribution. Buyers sourcing these units are usually working on lighting retrofits, new office fit-outs, warehouse automation, or energy compliance projects. What they actually check before placing an order tends to come down to a few practical things. Detection range and coverage angle matter because a unit rated for 12 meters at 110 degrees behaves very differently from one rated for 6 meters at 360 degrees. Mounting style is another real constraint. Ceiling-mounted, wall-mounted, and corner-mounted units are not interchangeable on a job site. Supply voltage and output type need to match the existing control wiring. And then there is the trade-off between price and lead time. A well-known brand like Leviton or Lutron might carry a four-week lead time on certain SKUs, while a lesser-known manufacturer with equivalent specs could ship in days. Counterfeit risk is lower in this category than in semiconductors, but it is not zero, especially with popular PIR models that get re-labeled and sold through gray channels. Buyers also care about packaging. Some prefer individually boxed units for retail resale, others want bulk packs for a large installation. Certifications matter too, particularly UL listing for North American projects and CE marking for European ones. The tolerance on the detection threshold is worth checking as well, because a unit that triggers on a pet or a curtain moving in a draft will generate complaints.
