Lutron Maestro Dual-Tech Occupancy Sensor Switch 6 A MS-A202

Product Overview

The Lutron Maestro MS‑A202 is a single‑pole occupancy sensor switch that uses dual‑technology sensing (PIR + ultrasonic) to reduce false triggers while automating lighting control.

Rated for up to 6 A switching at 120–277 V, the MS‑A202 replaces a standard wall switch and requires a ground or neutral at the switch box. Finish varies by SKU.

Key Features

• Dual‑technology sensing: passive infrared (PIR) plus ultrasonic detection
• Electrical rating: 6 A switching at 120–277 V (single‑pole)
• Requires ground or neutral at the device location
• Adjustable time‑out and sensitivity
• Replaces a manual wall switch to provide automatic lighting control

How this switch functions

The MS‑A202 replaces a standard single‑pole wall switch and controls lighting using both PIR and ultrasonic sensing. PIR detects motion through changes in infrared energy, while ultrasonic sensing detects small movements; the two methods operate together within the device to determine occupancy.

• Occupancy sensing turns lights on when presence is detected and turns them off after an adjustable timeout when no presence is detected.
• The device provides settings for vacancy/occupancy mode and sensitivity adjustments for room tuning.

Electrical and load requirements

Verify the circuit voltage and load are compatible with the MS‑A202 rating before purchase and installation.

• Voltage: 120–277 V
• Maximum switching current: 6 A
• Configuration: single‑pole switching
• Wiring: requires ground or neutral at the switch box

Common applications

Typical indoor uses for the MS‑A202 include spaces where automatic lighting control is desired or required by code.

• Examples: offices, restrooms, classrooms, storage rooms
• Use: replacing a manual wall switch with sensor‑controlled switching

Finishes and SKUs

The MS‑A202 is available in multiple finish variants. Select the SKU matching the finish needed for the installation.

• Available SKUs/finishes: MS‑A202‑WH (White), MS‑A202‑SW (Snow White), MS‑A202‑BL (Black), MS‑A202‑LA (Light Almond), MS‑A202‑AL (Almond), MS‑A202‑IV (Ivory), MS‑A202‑GR (Gray), MS‑A202‑BR (Brown), MS‑A202‑TP (Taupe), MS‑A202‑HT (Hot)

Installation and setup notes

Confirm the switch box has the required ground or neutral conductor and that the circuit is within the rated voltage and current before installing. Configure vacancy/occupancy mode and adjust timeout and sensitivity after wiring.

• Follow local electrical codes and the device wiring diagram during installation.
• If unsure about wiring or code compliance, consult a qualified electrician.

Before You Order

Confirm the MS‑A202 model number and finish/SKU, and verify the switch box provides a ground or neutral and that the circuit and load fall within the device ratings.

• Match the desired finish to one of the available SKUs (MS‑A202‑WH, ‑SW, ‑BL, ‑LA, ‑AL, ‑IV, ‑GR, ‑BR, ‑TP, ‑HT).
