PTO SHAFT, Proven Performance, Realized in Reality CTLA's Power Transmission Shaft (PTO-shaft) is a key component of the aircraft secondary powertrain, transmitting the high-speed rotational power generated by the aircraft engine drive unit (EMAD) to the gearbox (AMAD). By applying high-strength, lightweight titanium material for the first time in the world, we have achieved both weight reduction and durability, while implementing outstanding stability and reliability through our proprietary electron beam welding technology optimized for high-speed rotation and high-speed precision balancing technology. In particular, this product, which is currently being mass-produced and delivered to the KF-21 fighter jet, has demonstrated excellent power transmission performance while minimizing vibration even in extreme environments. CTLA is leading technological innovation in the field of high-speed rotational machinery, spearheading the self-reliance of domestic aircraft components and advancing into the global market.

MDCX, multipin coax connectors, offer low VSWR of 1.25:1 (typ) up to 10 GHz (max mated pair), maximum overall diameter of 0.125" fitted into low-profile micro-D housing, with constant 50 Ohm airline impedance. MDCX coaxial contacts are compact in size allowing multiple high density connections in a Micro-D style shell for applications where space and weight savings are important. No cumbersome spring mounts are required. These connectors are also available with locking post mechanisms or blindmate hardware attachment.

The ACTUS® CORE-5 is the latest development of our Dot Sight lineup. It delivers the same high-end optical performance and legendary durability as our existing CORE Dot Sights, now with enhanced features based on feedback from professional users. The ACTUS® CORE-5 offers three reticle designs and improved ergonomics, with relocated illumination controls on the top for ambidextrous operation—ensuring seamless adjustments while staying clear of chest rigs and plate carriers when slung. A dedicated night vision override switch allows for instant adaptation to sudden lighting changes, while the CR2032 battery provides an impressive 20,000-hour runtime at Level 8 brightness.
