Elevators must be safe and comfortable. Encoders from HEIDENHAIN, AMO, and RENCO make this possible. When installed on the main motor, brakes, shaft copying system, and doors, these encoders help the elevator car start gently, stop at just the right height, rapidly open and close its doors, and smoothly speed off again, all while meeting the highest safety standards. They also deliver the data needed for operational monitoring.
Ruggedness, reliability, and high resolution are key qualities of HEIDENHAIN rotary encoders. These characteristics make them proven and dependable motor control solutions on conventional traction elevators, able to meet the following elevator manufacturer requirements:
- High speed
- High travel height
- Compact design
- Low operating cost
- Numerous electrical interfaces to downstream electronics

KCI 419 Dplus rotary encoder for elevators: two-dimensional is outdated
The KCI 419 Dplus inductive elevator rotary encoder delivers far more than position feedback for motor control on traction elevators. It can also detect the brake stroke without additional microswitches and measure the brake temperature. The KCI 419 Dplus is therefore optimally suited for brake monitoring. Via the EnDat interface, it even provides diagnostic data to downstream electronics, which can then derive the brake status (released or engaged) and the level of brake wear.
Traction elevators of the future won’t need microswitches for brake release monitoring. In the more distant future, elevators will be cableless, enabling horizontal travel.
