These units are designed for collar attachment to birds such as parrots or macaws with strong aggressive bills. These units can also be used on small & medium sized mammals who require a stronger transmitter casing than our normal epoxy coating.
Specifications
| Model | Weight | Standard Life | Lifespan range | Dimensions: L x Diameter (mm) |
|---|---|---|---|---|
| SB-2C | 5.0g | 5 months | 3-6 months | 14 x 9.5 |
| SB-2C | 6.2g | 10 months | 6-12 months | 19 x 9.5 |
Note: Because the larger (6.2g – 10 month) SB-2C unit uses two batteries in parallel, it must not be stored for more than 2 months prior to use.
Frequency Range: 138 – 235 MHz.
Transmitter: Crystal controlled two-stage design pulsed by a multivibrator.
Pulse Width (standard): 19 milliseconds.
Pulse Rate (standard): 35 pulses per minute (ppm). Available from 20-120ppm.
Power Output: Set to use available battery power over the required transmitter life.
Activation: Removing an external magnet starts the transmitter. Replacing the magnet stops the transmitter.
Housing: The battery and transmitter are hermetically sealed in a brass case.
Antenna: Stranded stainless steel cable covered with a black nylon coating. Additional layers of shrinkable tubing reinforce the antenna at its base.
Options
Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. At the standard settings, the pulse rate changes from ~25 ppm at 0°C to ~40 ppm at 40°C. Each transmitter is supplied with a plotted calibration curve. This option adds ~0.05 g to the finished weight of the transmitter.
