Digging deeper into application-level nuances, current sensing has bifurcated into closed-loop and contactless topologies, each addressing distinct design challenges in power management and safety isolation. Magnetic switches, whether latch or push-pull configurations, provide reliable digital feedback in harsh environment controls. Position sensing ranges from linear displacement measurement critical to robotic actuators to rotary angle detection for steering and valve control. Speed sensing applications have similarly branched into motor speed monitoring within factory automation and wheel speed detection for traction control systems in automotive contexts. Concurrently, the choice between discrete and integrated product types reflects varying needs for design flexibility versus turnkey solutions. Output interfaces span analog voltage or current signals alongside digital protocols like I2C, SPI, and PWM, accommodating both legacy systems and next-gen IoT architectures. Finally, technology variants such as in-plane sensing, with single-axis and dual-axis configurations, answer demands for compact gyroscopic replacement, whereas out-of-plane multi-axis or single-axis techniques enable more complex motion tracking and stabilization tasks.
