Receiver module.
Control-ready signal.
The 200x receiver module installs inside the unit control box, receives the wireless switch signal, and delivers a door-state input to the configured control system.
Wireless door-switch control for refrigerated fleets
Less wiring.
Less wiring.
More visibility.
Trusted by some of the largest fleets in the country.
SensorLINK™ 200x replaces vulnerable hard-wired door-switch runs with a wireless system that sends door-open and door-closed status to compatible Thermo King and Carrier refrigeration controllers.
For refrigerated vans, trucks, and trailers, the door-switch response is configured around the fleet: shut the unit down during non-cooling door-open events, adjust operation, log activity, or send data to telematics.

SensorLINK™ 200x wireless system
Wireless door-switch control, configured for the fleet.
The receiver connects the wireless door-switch signal to a compatible unit controller or data logger—without long sensor runs across the fleet.
Receiver module.
Wireless door switch
Low-profile, weather-resistant external-antenna switch reports cargo-door open and closed status without a long hard-wired run.
Harness + relay options
Custom harness and relay options adapt the door-state input for compatible Thermo King and Carrier control systems and the operating rules set by the customer.
System configurations
Configured around the refrigeration unit.
Every configuration starts with the vehicle and unit: Thermo King or Carrier; van, truck, or trailer; single- or multi-temp; and the fleet’s door-open operating rules.
Single or multi-temp
- 200x receiver module
- Up to three wireless door sensors
Single-temp
- 200x receiver module
- SensorLINK harness
- Wireless door sensor
Multi-temp
- 200x receiver module
- SensorLINK harness
- SensorLINK relay + door sensor
Built for fleet operations
Cut reefer run time when doors are open.
When a cargo door is open during delivery, the refrigeration unit can be running against warm, humid outside air. SensorLINK gives the controller the door-state input it needs to follow the fleet’s specified response.
Avoid needless run time.
A compatible controller can shut the reefer down or follow a programmed operating mode while the door is open, instead of running against warm outside air.
Protect temperature integrity.
Door-open status helps the unit respond appropriately during delivery, reduces heat gain, and can support alarm, event-log, or telematics workflows.
Retrofit the fleet.
The wireless door switch, receiver, harness, and relay options can be configured for refrigerated vans, trucks, and trailers—one unit or an entire fleet.
