Lutron Motion Sensor Switch Specs: A 7-Step Wholesale Ordering Checklist

If you are the one who turns a contractor's request for a Lutron motion sensor switch into an actual purchase order, this checklist is for you. Inside sales, wholesale buyer, distribution spec coordinator—whoever signs the PO. The contractor usually knows the product family, but not always the model number, the voltage, or the code requirement hiding behind it. Your job is to make sure the order lands right the first time.

Seven checks, in the order I would run them. I have spent 12 years coordinating lighting controls orders at a regional electrical distributor. Last quarter we processed roughly 90 rush orders across our lighting control lines, and more than a few needed a spec correction before they shipped. This list is what those corrections taught me.

When you sell motion sensors wholesale, the unit price is the smallest part of the real cost. The expensive part is the return, the callback, and the electrician standing on a ladder waiting for the replacement. These checks are how we keep that from happening.

1. Start With the Application—Not the Part Number

Many buyers start at the sensor spec sheet. Start further back: what is the sensor supposed to do? A motion sensor is not one product. It is either an occupancy sensor or a vacancy sensor.

An occupancy sensor turns the lights on automatically when someone enters the room, then turns them off after a time-out. A vacancy sensor must be switched on by hand; it only turns the lights off automatically. The two serve different rooms and different user habits, and ordering the wrong one creates a service call. The person using the room will think the light is broken because it switched on by itself when they did not want it to.

The second split is indoor versus outdoor. A Lutron outdoor motion sensor lives a different life than an indoor wall switch sensor—weather, temperature swings, insects, sun loading, different housing, different lens. Make that call before you look at part numbers.

2. Check Voltage, Wiring, and the Three-Way Trap

This is the least glamorous step on the checklist, and the one that creates the most returns. A sensor switch is a line-voltage device. It gets wired into the lighting circuit the same way a regular switch does.

A lighting circuit in an office or warehouse is often 277 V. A house or small retail space is more likely 120 V. Not every sensor model is rated for both, so the spec sheet has to match the job. If you are ordering stock for a distributor, keep the voltage variants visible in your item descriptions. A buyer searching by keyword instead of voltage is how the wrong product sneaks into the cart.

Then ask a wiring question before you close the quote: how many switch locations control this load? If the answer is two, the single sensor will not do it alone. You need a companion switch from the same product family. It is remarkable how many jobs stall because the order shows up complete except for that companion component. The electrician makes that discovery on a Friday afternoon. Every time.

3. Do the Load Math (Track Lighting Included)

This step is easy to skip because the calculation is not printed on the sensor datasheet. It is on the fixture schedule. A sensor switch has a maximum load rating, and that rating is often stated separately for incandescent, LED, or motor loads. If the connected lighting load exceeds it, the sensor will fail early or nuisance-trip.

Track lighting is a great example because it is easy to under-count. When someone asks me how to choose track lighting for wholesale, the answer is always the same: count the actual heads first, total the wattage of the LED modules (not the equivalent wattage), then add a 20 percent buffer before you match that load to a control.

The other part of the math is the driver. LED drivers have an inrush current at startup that is much higher than their steady-state draw. The sensor's relay has to survive that surge, not just the running watts. If the datasheet lists a maximum LED load, use that number. If it does not, ask before you order.

When the lighting controls specifications and the fixture schedule sit on different pages of the drawing set, they will disagree somewhere. Finding that gap before the order ships is a lot cheaper than finding it on the job site.

4. Match the Coverage Pattern to the Room, Not the Catalog

A sensor's coverage is not a square footage number; it is a shape. Most spec sheets include a top view and a side view, and the shape is there for a reason. A 180-degree sensor with a wide cone is fine for an open room, but not for a long corridor or an aisle lined with tall shelving.

Mounting height changes the coverage as well. A sensor designed for an 8-foot ceiling will behave differently at 14 feet. The pattern gets larger and the detection of small motion gets less reliable. Ask for the mounting height before you finalize the model.

Partitions, lockers, and shelving all block line of sight. That is where dual-tech sensing earns its keep. It costs more, and sometimes the extra cost is the right call. Sometimes it is overkill. The coverage pattern is what tells you which.

5. Outdoor: Check the Envelope Before the Sensor

Outdoor sensors get specified like indoor ones until the first cold night. Then the phone rings.

A Lutron outdoor motion sensor is a different product family for good reasons. It has to handle moisture, temperature extremes, UV exposure, and insects. The number to check is the IP rating, plus any wet or damp location listing that applies to the installation. If the spec sheet does not say outdoor-rated, do not assume it can go outside.

There is a functional mismatch worth catching at the quote stage too. Motion sensing is not photocell control. A motion sensor reacts to movement; a photocell reacts to light level. If the client wants lights on from dusk to dawn every night, they need a photocell or a timeclock, not a motion sensor. If they want security lighting that reacts to a person approaching, the motion sensor is the right tool. The quote should say which one you priced.

6. Code Compliance: Verify, Don't Guess

I am not a code official, and you should not have to be one either. But somebody on the order chain needs to know whether the project actually requires an occupancy sensor at all.

Most commercial energy codes in the U.S. require automatic shutoff of lighting in many space types. The two documents you will run into most often are ASHRAE/IES Standard 90.1 and California Title 24, Part 6. Outside California, the local jurisdiction may have adopted one of those editions or the IECC, possibly with amendments (Source: ashrae.org and energycodes.gov).

I will not give you a blanket rule from memory, because the code edition matters, the building type matters, and the authority having jurisdiction has the final word. When a project has a lighting controls specification that says sensors on the drawing but no sensor schedule, ask what code cycle was used for the permit. It saves everyone from ordering the wrong product.

7. Packaging, Lead Time, and the Buffer You Can't Skip

Last is the part that gets decided when the quote is already late. Wholesale freight is part of the real cost, and full carton quantities ship better than mixed fills. Check the pack quantity before you multiply the unit price.

If you need product for a hard deadline, build a buffer into the schedule. Not just from the factory—from your own warehouse. I learned this the hard way. In early 2024, a contractor needed 140 occupancy sensors on site within 36 hours for a Friday inspection. Normal fulfillment was four days. We found stock at another branch, paid roughly $700 extra in freight on top of a $5,600 base order, and got the sensors there Thursday evening. The alternative was a failed inspection and a penalty that would have erased any savings from a cheaper supplier.

There was a cheaper option on the table. Another supplier's product was in stock and 8 percent less expensive. The spreadsheet said it would meet the deadline. My gut said the job was too sensitive for a substitution we had not tested, so we paid for the expedite and stuck with the original spec. I would make the same decision again.

The cheapest order is not the one with the lowest unit price. It is the one that arrives on time, matches the voltage, and does not need a second trip. That is the version I want to sell, because it costs me less too.

One closing reminder, with a time stamp. This spec guidance was accurate as of Q1 2026. The Lutron catalog changes, code cycles change, and freight times change with the season. Verify part numbers, current lead times, and the adopted code edition before you commit the PO.
