Spring-loaded LVDT_Manufacturer_OEM/ODM Custom Solutions

Spring-loaded LVDT Product Introduction

The HD-T120 AC Series spring‑loaded LVDTs are high‑precision AC‑output sensors with <0.25% linearity, <0.1% repeatability, and infinite resolution. Housed in a stainless steel 12mm IP65 body, they offer standard strokes from 10mm to 50mm (customizable). A precision linear bearing, hardened tip, and built‑in shielding ensure smooth movement, >10⁷ cycles life, and EMI protection. Standard M2.5 threaded tip enables easy replacement. Ideal for precision dimensional gaging, online parts inspection, high‑repeatability comparison, and pressure vessel monitoring.

HD-T120 AC Datasheet

Performance

Code	Stroke Range (mm)	Sensitivity, mV/V/(mm)
SD-T120-100-AC	10	120
SD-T120-150-AC	15	80
SD-T120-200-AC	20	60
SD-T120-250-AC	25	48

All values are nominal unless otherwise noted. Dimensions are in mm unless otherwise noted.
FR: Full Range is the stroke range, end to end; FR= S for 0 to S stroke range.
FRO (Full Range Output): Algebraic difference in outputs measured at the ends of the range.
