Product Description

The 42540-6128 is an ARC EA401A encoding altimeter that combines cockpit altitude display with an internal encoder for Mode C/S transponder reporting. This instrument receives static pressure input and outputs uncorrected pressure altitude via Gillham gray-code format to surveillance and ADS-B equipment. The altimeter mounts in the instrument panel while the encoder interfaces with the avionics harness.

Installation requires plumbing into the aircraft static system and connecting to transponder systems per the aircraft maintenance manual. Verify part-number applicability before installation.
