Celesco's M150 transducer has a range of 1.5 inches, fits into tiny spaces, and is good for applications such as biomedical and robotics. The aluminum transducer body measures just 0.74 × 0.74 × 0.38-in., or the approximate size of thumbprint, with a 0.014-inch diameter nylon-coated stainless steel measuring cable. It offers extremely durable construction and a high degree of reliability. The devices don't require precise manual alignment so users need not sacrifice stroke range to properly position the sensor.
