SENSOR SWITCH

Sensor Switch is a brand of lighting control and occupancy sensing products, now part of Acuity Brands. The line includes passive infrared (PIR), microphonic, and dual-technology sensors, along with the low-voltage power packs and relay units required to integrate them into commercial lighting circuits. Products are used to switch lighting loads automatically based on occupancy and, in some models, ambient light level. 3G Electric supplies the Sensor Switch line globally, with 56 SKUs currently listed. The range covers ceiling-mount and wall-mount occupancy sensors, wall-switch style sensors with integrated photocells, and hard-wired power and relay control units. Technical buyers will find models that operate on 12 to 24V DC, 120 to 277V AC, or 120/240/277V AC input with 15V DC output for low-voltage sensor power. Load ratings include up to 800W for fluorescent, incandescent, and LED lighting. Some wall-mount units require a neutral wire, while others do not; nightlight options are available on selected models. Detection technologies include PIR, microphonic, and combinations of both. The power packs and relay units are designed to supply low-voltage sensors and provide hard-wired communication. 3G Electric supports the line with logistics and quotation services for plant engineers, maintenance managers, and procurement specialists. The catalog includes part numbers such as CM PDT 9 WR, MP20, PP20, SP20, WSXA WH, WSX 2P NL WH, WSX 2P WH, and WSX PDT WH. These products are intended for commercial and industrial lighting control where automatic switching can reduce energy consumption. Specifiers should confirm voltage compatibility, neutral wire availability, load type, and whether photocell control is required. 3G Electric provides access to the Sensor Switch range without regional restrictions, shipping to international destinations. For detailed specifications, wiring diagrams, and compatibility with existing systems, consult the manufacturer's documentation. 3G Electric can assist with part number selection and order fulfillment.

Frequently asked questions

Common questions about SENSOR SWITCH from 3G Electric.

What is the difference between the Sensor Switch MP20, PP20, and SP20 power packs?

The Sensor Switch MP20 and SP20 accept 120/240/277V AC input and provide 15V DC output. The PP20 accepts 120V AC input and provides 15V DC output. All three are hard-wired power and relay control units designed to supply low-voltage sensors and provide hard-wired communication in commercial lighting control systems. The MP20 and SP20 are suitable for multi-voltage applications, while the PP20 is limited to 120V AC systems. Selection depends on the available supply voltage and the requirements of the connected sensors.

Do Sensor Switch wall-mount occupancy sensors require a neutral wire?

It depends on the model. The Sensor Switch WSXA WH requires a neutral wire for installation. The WSX 2P NL WH, WSX 2P WH, and WSX PDT WH do not require a neutral wire. All four operate on 120 to 277V AC and are rated for fluorescent, incandescent, and LED loads up to 800W. The WSX 2P NL WH includes a nightlight feature; the others do not. Confirm wiring availability before selecting a model.

What detection technology does the Sensor Switch CM PDT 9 WR use?

The Sensor Switch CM PDT 9 WR is a ceiling-mount occupancy sensor that uses passive infrared (PIR) and microphonic detection. It operates on 12 to 24V DC. This dual-technology approach is intended for automatic lighting control in commercial spaces. The sensor requires a compatible low-voltage power pack, such as a Sensor Switch MP20, PP20, or SP20, to interface with the lighting circuit. Verify power pack compatibility and coverage area before installation.

Can Sensor Switch occupancy sensors control LED lighting loads?

Yes. Many Sensor Switch occupancy sensors, including the WSXA WH, WSX 2P NL WH, WSX 2P WH, and WSX PDT WH, are rated for fluorescent, incandescent, and LED lighting loads. The wall-mount models listed support loads up to 800W at 120 to 277V AC. For LED loads, confirm that the driver inrush current and steady-state current are within the sensor's rating. For low-voltage sensors like the CM PDT 9 WR, the connected power pack or relay unit determines the load capacity.

What is the operating voltage range for Sensor Switch low-voltage sensors?

Low-voltage Sensor Switch sensors, such as the CM PDT 9 WR, operate on 12 to 24V DC. These sensors are typically powered by a separate power pack or relay control unit that converts line voltage to 15V DC. The power pack models MP20, PP20, and SP20 provide 15V DC output from 120/240/277V AC or 120V AC input, depending on the model. Ensure the sensor's voltage requirement matches the power pack output.

Does 3G Electric ship Sensor Switch products internationally?

Yes. 3G Electric supplies Sensor Switch occupancy sensors and power packs globally. The catalog includes 56 SKUs, and orders can be shipped to international destinations.
