te.com DC-EC SERIES General purpose DC LVDT SPECIFICATIONS High level 10VDC output Stroke ranges from 0.05 to 10in 0.25% linearity Reverse polarity protection Double magnetic shielding Stainless steel housing Imperial or metric threaded core The DC-EC Series DC operated LVDTs combine a computer-designed AC LVDT with custom integral signal conditioning to achieve premium Features performance. Operating on a nominal 15VDC supply, the DC-EC Bi-polar DC operation Series delivers an extremely linear, low noise, yet high frequency Shock and vibration tolerant response 10VDC output. Captive core option (available on Innovative design and manufacturing techniques further enhance the select models) DC-EC performance and cost efficiency. The micro-miniature AISI 400 Series stainless steel components employed were meticulously selected for maximum stability housing and thermal performance. Vacuum encapsulation of all elements affords CE compliant excellent shock and vibration tolerance, while double magnetic shielding Calibration certificate supplied with provides the utmost protection from stray fields. each unit Like in most of our LVDTs, the DC-EC windings are vacuum impregnated with a specially formulated, high temperature, flexible resin, Applications and the coil assembly is potted inside its housing with a two-component Materials testing epoxy. This provides excellent protection against hostile environments Z-axis position feedback for punch- such as high humidity, vibration and shock. presses Available in a variety of stroke ranges from 0.05 to 10 inches, the DC- Microscope X-Y stage position control EC Series can be configured with a number of standard options including Medical imaging metric threaded core, guided core and small diameter/low mass core. Automotive suspension testing Captive core option: The DC-EC features an optional captive core design Flight simulators (available for most models) that greatly simplifies installation. The core rod and bearing assembly includes a Bronze bearing on the front end for self-alignment, while a PTFE sleeve allows low-friction travel through the stainless steel boreliner (spool tube). The core rod and the bearing assembly are both field serviceable.
