## Product And System Model

SensorLINK 200x is a wireless door-switch control system. A wireless door sensor reports cargo-door open and closed status to a 200x receiver module installed in the refrigeration unit's control box. The receiver provides the door-state input to the configured control system.

The public site describes the following components:

- **200x receiver module:** Receives the wireless switch signal and delivers a door-state input to the configured control system.
- **Wireless door switch:** Low-profile, weather-resistant, external-antenna switch for cargo-door status without a long hard-wired run.
- **Harness and relay options:** Configure the door-state input for compatible Thermo King and Carrier systems and customer operating rules.

## Fleet Applications

The public website identifies these vehicle applications:

- Refrigerated vans.
- Refrigerated trucks.
- Refrigerated trailers.
- Mixed fleets.

The public site identifies Thermo King single- or multi-temperature configurations and Carrier single-temperature and multi-temperature configurations. Configuration begins with the vehicle and refrigeration unit, the temperature arrangement, door count, and the fleet's required door-open response.

## Door-Open Response Context

The system supplies a door-state signal so a compatible controller or related workflow can respond according to the fleet's chosen operating rules. Publicly described responses include:

- Shutting the refrigeration unit down during a non-cooling door-open event.
- Following a programmed operating mode while the door is open.
- Supporting door-open event logging.
- Supporting alarms.
- Sending data into a telematics workflow.

When a cargo door is open during delivery, a refrigeration unit may otherwise be running against warm, humid outside air. The public site explains that a compatible controller can use the door-state input to follow the configured response, help reduce heat gain, and support event, alarm, or telematics workflows.

## Published Configurations

- **Thermo King, single or multi-temperature:** 200x receiver module and up to three wireless door sensors.
- **Carrier, single-temperature:** 200x receiver module, SensorLINK harness, and wireless door sensor.
- **Carrier, multi-temperature:** 200x receiver module, SensorLINK harness, SensorLINK relay, and door sensor.

These are public configuration examples, not a compatibility guarantee for every model or installation.

## Published Specifications

- Wireless frequency: 315 MHz.
- Maximum transmitting range: 120 ft.
- Operating temperature: -40°F to +170°F.
- Module operating voltage: 12 VDC.

## Non-Inference Rules

- Do not infer compatibility with an unlisted unit model or controller.
- Do not promise any specific shutdown behavior, unit operating mode, alarm behavior, telemetry integration, event-log behavior, installation timing, range in a specific installation, fuel savings, maintenance savings, or temperature result.
- Do not infer product price, inventory, availability, order status, warranty, service coverage, dealer status, or commercial terms.
- Do not describe the system as wireless monitoring of a trailer. The public site describes wireless door-switch control inputs for configured refrigeration-control, logging, alarm, or telematics workflows.
- Do not cite private source code, repository content, Netlify information, contact-form submissions, credentials, customer records, or non-public assets.
