With the launch of the contact-free, absolute Vert-X 13 angle sensor, Variohm is defining a new class of rotary position sensors, combining aspects of miniaturisation, ruggedness and precision in a compact sensor. The Vert-X 13 absolute rotary position sensor is ideal for applications in confined spaces.
At a diameter of just 13 mm, the sensor, based on a magnetic, contact-free measuring principle, is so compact that it is ideal for detecting the angles of swinging and gripper arms or for precisely measuring camera positions. In addition, the Vert-X 13 has a long life, even in the most demanding environments. The reasons for this are the stainless steel case and shaft and the smooth-running, precision ball bearings, which permit radial and axial shaft loadings of up to 5 N. Another feature contributing to the long life and lack of susceptibility to condensation, is the contact-free, magnetic and absolute measurement system. This allows customer-specific measurement angles up to 360°, delivers up to 14-bit resolution across the entire measurement range and has impressive repeatability to max. 0.1°.
In developing the Vert-X 13, there was attached great importance to producing a modular concept, to create a high degree of flexibility for users. The resulting variability makes it easy and cost-effective to adapt the absolute rotary position sensor to differing customer requirements. The configuration possibilities include a number of different interfaces. The available options include ratiometric (analogue) voltage output, an incremental output signal (A,B,Z), a serial SSI or SPI interface and a PWM interface. Other customer-selectable features are the required type of protection (up to IP67), customer-specific shaft outputs and individual connection variants. Additional flexibility is provided by programmable customer-specific measurement angles and optional redundancy. Users can also freely choose between rising and falling signals.
