Linear position sensors

Temposonics linear-position sensors can generate up to 20 simultaneous position outputs along a given sensing element, making them a cost-effective replacement for traditional proximity sensors.

Features & benefits

  • Magnetostrictive sensors, suitable for multiple-magnet applications, are capable of stroke ranges greater than 5,000 mm; can provide resolution as small as 1 µm

  • Sonic wave sensing devices use a high-resolution clock to determine accurate absolute position between fixed point and moving magnet; one return signal created for each magnet; if magnets are added, there is an additional signal generated for each magnet from the single interrogation pulse

  • R-Series are smart sensors for fast, synchronized position control; G-Series are programmable sensors with built-in diagnostics for applications needing analog, start/stop, and PWM outputs; E-Series are designed for applications requiring simple position feedback
