Posital Fraba Encoder

Posital, a member of the international FRABA Group, is a prominent manufacturer of position and motion sensors, with their encoders being widely used in industrial automation, robotics, and mobile machinery applications. They are known for their broad range of sensors and unique build-to-order manufacturing process.

Key Encoder Types and Technologies

Posital offers both rotary and linear position sensors, utilizing both optical and magnetic sensing technologies to cater to diverse industrial needs.

Absolute Encoders: Provide a unique position value immediately upon power-up, even after a power loss, which is critical for safety and automation applications. Many are battery-free multi-turn versions that use the proprietary Wiegand effect technology to track revolutions. They are available with a wide variety of interfaces and resolutions.
Incremental Encoders: Offer a cost-effective solution for applications primarily needing feedback on speed and direction, rather than absolute position. They generate a series of pulses as the shaft rotates, and the position is determined by counting these pulses from a known reference point.
Kit Encoders: Compact and cost-efficient solutions designed for integrated motor feedback, offering a combination of accuracy and reliability in a small form factor.
Linear Sensors: These are draw wire sensors used to monitor linear motion with lengths ranging from 1 m to 15 m.
Inclinometers: Also known as tilt sensors, they are designed to measure the angle of an object with respect to gravity and are commonly used in construction and mining equipment.
