IR-TAG-LD responder
Comparator LLC has developed the IR-TAG-LD
The main functions of the responder:
- Identification
- Heat detection
- Rumination

Full compatibility with market leaders:
- Allflex, SCR, Lely, Milkline
Requires no modifications:
- Full compatibility with H-TAG-LD and HR-TAG-LD SCR manufacturers.
- Requires no software or settings.
- Simply place the transponder on the cow and enter the ID into your database.
- Compatible with DataFlow, Horizon (T4C) software

IR-TAG-LD responders feature
IR-TAG-LD responders ensure the operation of the identification system, measure activity, and chewing activity (rumination), which makes it possible to replace the failed SCR responders and restore the normal operation of the identification system, milk counting, and heat detection.
- Manufacturer BY.
- Cheaper pricing policy.
- Modern electronic components.
- Fast service and replacement.
- Compatible with IDU510, IDU530, BU500.
The IR-TAG-LD responder does no changes to the hardware or installation of additional software.
Each responder has a unique identifier and works with software Horizon/ T4C/DataFlow II/ DataFlow, like the original SCR HR-TAG-LD Responder.
The responder works with IDU530 / BU500 antennas (Lely Astronaut A5 milking robot) and IDU510 / BU500 antennas (SRC and Milkline milking units)
The responder works together with SCR H-TAG-LD and HR-TAG-LD responders.

Reliability and high accuracy
The PCB has a low weight and dimensions, which reduces its damage during operation.
The tag uses a MEMS accelerometer and digital signal processing to detect cow heat and measure rumination.
This solution reduces current consumption and increases the accuracy of cow heat detection.
Features of the design of the IR-TAG-LD responder
The case of the responder IR-TAG-LD is made of impact-resistant plastic.
To extend the responder’s operating time, a 2700 mAh high-capacity battery was used.
The battery is not soldered to the PCB and is in a separate compartment, which prevents it from breaking off from the PCB due to shocks during operation.
