APM | Avionics Panel Meter

OTEK’s Model APM is a four (4) digit green, red or blue LED indicator that accepts standard avionics power of 5-32VDC (Green, Red or Blue digits) and intensity control voltage of 1.5 – 5V 50-440Hz (or DC/Resistance). OTEK’s exclusive powerless technique allows the APM to be loop powered causing a maximum of 5VDC burden to the loop. The APM only requires 2 wires to operate.

The heart of the APM is an ASIC that accepts VDC or mADC and can be scaled (internally) to any value. The unit mounts in a standard avionics 1″ diameter hole with four (4) mounting screws and connects to Power and signal via a “Twist Lock” circular connector (DBC53H-10-6P, Mating Cable End: MS347640 (L or M) -6S).

The APM is fully sealed and it is not affected by differential pressure, liquid spray (NEMA4X), or humidity (See Specs.).
