These cylindrically shaped units are housed in a brass case for maximum durability. They can be setup as implants (snakes), backpacks (large birds), bolt-on (turtles), or collar-style (small mammals), and customized to meet your exact requirements.

Frequency Range: 138 to 235 MHz.
Pulse Width (standard): 24 milliseconds (ms). Available from 18-32ms.
Pulse Rate (standard): 40 pulses per minute (ppm). Available from 5-120ppm.
Housing: The battery and transmitter are hermetically sealed in a brass case. For the implant setup, the case is coated with multiple layers of a biologically inert butyl rubber compound and a small groove is added to allow for suturing.
Attachment: A number of mounting options are available (see photos above). Implant: no mounting setup, Backpack: a brass tube is attached at each end for either a Teflon ribbon or cable harness. Bolt-on: brass tabs are attached at the mid-point or at the ends for screw attachment. Collar: the unit is attached to a 9mm wide neoprene-impregnated polyester collar fastened with a self-locking nut and captive stud.
Antenna: Stranded stainless steel cable covered with a black nylon coating. One or two layers of shrinkable tubing reinforce the antenna at its base.
Activation: Holding a magnet next to the unit starts the transmitter. Passing it over again stops it.
Options
Note: Multiple sensors can be added to a single unit.
Mortality (suffix “M”): After a preset period (1 to 23 hours) of no movement, the pulse rate changes (to an increased rate OR a double pulse) to indicate mortality. After the mortality mode has been triggered, any motion resets the transmitter to the normal pulse rate. Locking mortality is also available.
Activity (suffix “A”):After a preset motion sensitivity or angle has been reached, the pulse rate will change (to an increased rate OR a double pulse) to indicate activity.
Temperature (suffix “T”): An increase or decrease in temperature results in a corresponding increase or decrease in pulse rate. The high and low temperature limits are set by the user (0-50C), as is the pulse rate (5-120ppm) at each extreme. Each transmitter is supplied with a plotted calibration curve.
Duty Cycling (suffix “D”): To conserve battery power and extend the lifespan, the transmitter can be programmed to enter low-power mode each day (from 1-23 hours). During this low-power mode, the unit can be silent (0ppm) or programmed to pulse at a greatly reduced rate (4, 6, or 8ppm).
