THE DIFFERENCE IS IN THE DESIGN
Tekin servos are crafted from the highest quality materials available. CNC Precision Cut gears provide an extremely smooth and efficient drive train. 6061-T6 machined aluminum 3-piece o-ring housings provide strength and protection from the elements while the finish quality and design are second to none. Sleek chamfered edges and bold lines combined with a matte anodized finish are sure to accent any build.
Included with the T-440 Servo is a machined aluminum Crowbar Dual Clamp 25T servo arm.
ADVANCED TECHNOLOGY
Digital Magnetic Position Encoder (DPE)
Our servos use Digital Magnetic Position Encoding rather than a standard potentiometer, which gives Tekin servos the industry leading accuracy, linearity and consistency.
Accuracy
Precise linear movement through the entire motion range with less than .2 degrees of deviation from start point to end point make Tekin the superior performance product. Low deviation translates to pinpoint accuracy not found in other servos, which tend to wander and center poorly. Tekin is built to last at peak performance.
Linearity
Potentiometer servos can be up to seven degrees non-linear from end point to end point, creating a disconnected feel from your transmitter. Tekin servos eliminate this disconnect, giving you a linear feel and more precise control over your servo movement and position.
Consistency
Performance is important but we are all about consistent performance. Potentiometer performance drifts due to many variables; heat, age, component quality, etc. Magnetic Encoding is a rock-solid, repeatable and consistent technology bringing an unmatched consistency to Tekin servos. Tired of constantly trimming your servo and having response feel different during times of longer usage? Tekin servos are the answer.
Efficiency
Accuracy drives efficiency. A servo that has to work less to center or stop without overshooting position is using less energy. This means less heat build-up, less component fatigue and longer life.
Adaptability
Tekin Servos come with a series of unique features; DPE technology lets you set the center point anywhere, and servo travel limits can be set without reducing the End Point Adjustments (EPA’s) on your transmitter. Most servos are limited to 90° travel in each direction with a physical stop point; DPE means that Tekin servos can be programmed to travel beyond 360°-- up to 5 full rotations in each direction!
Element Proof
Dependable, no matter the terrain. Element Proof Tekin products are designed to handle water, mud & snow within reasonable restrictions. While we are not afraid to take on the elements, submerging is not recommended.
