Trig TT23 and TT23G Class 1 Mode S Transponders with Built-in Altitude Encoder and optional built-in GPS

Note: Price does not include tariff.

The TT23 and TT23G are a very interesting new transponders. It is a Mode S transponder with a built-in altitude encoder, and a remote head - at a great price!

Description:
Simple to install, simple to use – The TT23 is the next generation of Trig’s compact Transponder line.

The new design is smaller and lighter than its predecessors, reducing instrument panel space and weight while introducing advanced features for pilots worldwide.

The TT23 is a fully certified Class 1, Mode S transponder with ADS-B Out, suitable for both VFR and IFR flight. Its compact form factor is ideal for aircraft with limited panel space, ensuring maximum efficiency without compromising performance.

Features:

The transponder is available in two versions:

TT23G: Features a built-in, ETSO-C199 certified GPS receiver – the ideal choice for pilots seeking an integrated ADS-B out solution. The TT23G is perfect for experimental and light sport aircraft looking to meet the requirements for ADS-B out in the United States. In markets when ADS-B equipage is voluntary, the TT23G is the perfect solution for enhancing conspicuity and safety.

TT23: For aircraft with a suitable GPS position source on board, the TT23 (without GPS) can be used as an ADS-B solution. An STC will be available to integrate with popular 3rd party GPS navigators, as well as the Trig TN70 Remote position source. For those that do not intend to equip with ADS-B out, the TT23 model is a high-quality, modern transponder with easy configuration options that make it suitable for any application. that make it suitable for a broad range of GA applications.

Product Design:

The TT23 and TT23G transponders are designed for easy installation. Both models are mounted remotely from the instrument panel, giving maximum flexibility on panel space and wiring.

The transponder is controlled by the popular TC20 control head. Well-known for its compact size, this takes up minimal space and depth in the panel. The controller has a built-in altitude encoder, saving additional space and weight.

The control head fits into a 57mm round hole, with the option of using a smaller compact mount hole. When fitted the depth of the controller is only 54mm, and connected to a wiring harness the depth is still only 85mm.

The TT23 is compatible with a wide range of aircraft and avionics systems, ensuring flexibility and adaptability.
