Product Description
Other Models

The AI-TEK 70085-1010-235 is a high-performance, passive variable reluctance speed sensor designed for precision rotational measurement in demanding industrial environments. Manufactured by AI-TEK Instruments (formerly known as AIRPAX), this sensor represents decades of expertise in converting mechanical motion into reliable electrical signals .

As part of the extensive 70085 series, the 70085-3030-235 utilizes variable reluctance technology to detect the speed of rotating ferrous targets without requiring an external power source. These self-generating sensors have been the cornerstone of control and protection circuits for years, trusted in applications ranging from aircraft engine controls to critical industrial machinery monitoring .

The sensor operates on a simple yet robust principle: when a ferromagnetic object (such as a gear tooth) passes the sensor's polarized tip, it changes the magnetic flux, inducing a voltage in the pickup coil. The frequency of the resulting signal is directly proportional to the rotational speed, while the amplitude varies with both speed and gap distance .
