Choosing Linear Position Measuring components

Linear position sensor selection starts with the stroke length and accuracy needed, then narrows by the sensing technology that fits your environment and budget. The same stroke length can be measured by four or five different technologies — each with trade-offs in cost, durability, and integration.

Specifications to confirm before ordering:

  • Stroke length (the measurement range needed)
  • Required accuracy and resolution
  • Output signal — analog (0–10 V, 4–20 mA), digital (SSI, CANopen, Profibus, IO-Link), or pulse
  • Mounting — in-cylinder, profile mount, external rod, draw-wire
  • Operating environment (oil immersion, washdown, vibration, temperature)
  • Redundancy requirements (functional safety SIL rating)
  • Power supply (typically 24 VDC, some loop-powered options)
  • Cable termination and connector type

Technology selection guidance:

  • Magnetostrictive (Temposonics-style): in-cylinder mounting, oil-immersed, durable, stroke lengths to several meters
  • LVDT: high precision over short strokes (millimeters to ~250 mm), excellent in harsh environments
  • Draw-wire: long strokes (meters), low cost, vulnerable to wire damage
  • Linear encoders (optical/magnetic): highest accuracy for machine tool axes, indoor environments
  • Resistive linear potentiometer: low cost, lower accuracy, suitable for non-critical applications

For functional safety applications (PLd, PLe, SIL 2, SIL 3), specify sensors with dual independent outputs — single-output sensors cannot meet the diagnostic coverage requirements regardless of intrinsic accuracy.

Can you supply obsolete MTS Temposonics or Balluff Micropulse sensors?
Yes — legacy magnetostrictive position sensors are some of our most common requests. Older Temposonics R-Series, BTL-series Balluff sensors, and Gefran linear sensors are typically available through our supplier network. Submit the part number for a quote.
Magnetostrictive vs LVDT vs draw-wire — which one?
Magnetostrictive is the standard for in-cylinder mounting and strokes from 100 mm to 7 m. LVDT excels at short-stroke, high-accuracy applications in harsh environments. Draw-wire is the cheapest for long strokes (multiple meters) but the wire is vulnerable. Send your application and we'll recommend a technology.
Does the sensor come with the magnet (for magnetostrictive)?
Not always. The magnet is sometimes a separate part, sized to the sensor's rod diameter and stroke. If you're replacing only the sensing element, the original magnet usually stays in place. Confirm what's included on the product page.
Are these new?
Yes. All products offered for sale by Enicstra are new. For obsolete or hard-to-find part numbers, we search our supplier network for new inventory.
What about safety-rated linear sensors?
For PLd, PLe, SIL 2, or SIL 3 applications, you need sensors with dual independent outputs and matching safety controller. We stock several certified options; send your required safety category when requesting a quote.
