Lutron Maestro Dual-Tech Occupancy Sensor Switch 6 A, (MS-B102-BL)

Product Overview

The Lutron MS-B102-BL is a Maestro dual‑technology occupancy sensor switch that replaces a standard wall switch to provide automatic lighting control.

It is rated for switching up to 6 A at 120–277 V, requires a neutral connection, and supports single‑pole and 3‑way wiring configurations.

Key Features

• Dual‑tech sensing (passive infrared + ultrasonic)
• 6 A switching capacity at 120–277 V
• Neutral required; supports single‑pole and 3‑way wiring
• Adjustable timeout and sensitivity settings
• Finish: Black (MS‑B102‑BL)

What this switch does

The MS‑B102‑BL replaces a standard wall switch to control lighting based on detected occupancy. It turns lights on when presence is detected (in occupancy mode) and turns them off after a user‑set timeout when no presence is detected.

• Automates wall‑switch lighting control
• Provides vacancy and occupancy mode options

Electrical load and wiring

This model is rated for 6 A switching at 120–277 V and requires a neutral conductor in the switch box. It supports both single‑pole and 3‑way configurations.

• Voltage: 120–277 V
• Maximum switching: 6 A
• Neutral required at the box
• Compatible with single‑pole and 3‑way wiring

Sensing technology and behavior

The MS‑B102‑BL uses dual‑technology sensing—passive infrared (PIR) plus ultrasonic. The combination is intended to provide broader detection capabilities than a single sensing method alone.

• PIR detects motion and heat changes in the sensor’s field of view
• Ultrasonic detects motion via sound‑wave reflections
• Dual‑tech can help in spaces where one sensing method alone may be limited

Applications and installation notes

Common applications listed for this model include energy‑code automatic lighting control and use in offices, restrooms, classrooms, and storage rooms.

Before installation, verify the switch box has a neutral conductor and plan the correct single‑pole or 3‑way wiring.

• Typical uses: offices, restrooms, classrooms, storage rooms
• Preinstallation check: confirm neutral in the box

Configuration and settings

The switch provides adjustable timeout and sensitivity settings and supports selecting vacancy (manual ON) or occupancy (auto ON) modes to match room use and local requirements.

• Adjustable timeout controls how long lights remain on after no activity is detected
• Sensitivity adjustment tailors detection range
• Selectable vacancy or occupancy modes

Before You Order

Verify the switch box has a neutral conductor and that the lighting load does not exceed 6 A.

• Confirm presence of neutral in the switch box
• Confirm circuit voltage is within 120–277 V
• Check that your lighting load does not exceed 6 A
