General-Capability Position Transducers Give Long-Range, Compact Package, and Flexible Mounting for OEMs

New Series M displacement sensors have same-day shipping for cost-sensitive applications.

CREEDMOOR, NORTH CAROLINA USA -- Firstmark Controls is now shipping the Series M general-capability position transducer that gives long displacement range, multiple mounting options, and size efficiency for OEM and high-volume applications. Available in volume and individual prices with same-day shipping, the Series M product line was developed using Firstmark Controls's extensive experience in delivering performance- and safety-critical position transducers for the aircraft, space, and automotive markets.

"The Series M position transducer gives the lowest cost per unit length of any draw wire sensor on the market today," said Ryan Beebe, Operations associate at Firstmark Controls. "The Series M line gives users choices for electrical outputs, mounting orientation, and displacement range -- all with same-day shipping."

The new Series M line has a host of features that give unparalleled value. With a maximum range of 85 inches (2159 mm), the Series M line has nearly double the capabilities of competing OEM-type sensors. A reduced displacement cable fleet angle increases repeatability and reduces cable overlap. Three options give users flexibility in mounting the Series M transducers. Over 50 are available for electrical connectors and signal conditioning. The Series M products allow mounting of Firstmark Controls's patented RoundAbout™ cable exit for 360° x 360° displacement cable orientation. This cable exit offers control over how and where the displacement cable moves relative to the application.

"The Series M products bring together some of the best elements of Firstmark Controls's design capabilities," said Ryan Beebe. "We allow for user-replaceable displacement cable via a labyrinth-type cable exit that also serves to restrict debris from getting into the drum area. And, with the RoundAbout™ cable exit, a winner of Design News' Best Product of the Year, the Series M products can dynamically follow motion in a 3D environment, eliminating the need for transducer relocation or pulleys." Key Series M features include:

• choice of analog (voltage divider or rheostat) or digital (quadrature) sensors
• optimum fleet angle for more repeatable displacement cable wrap
• low-inertia drum for improved frequency response
• fixed or adjustable mounting features
• compatible with self-tapping or washer/nut screws
• RoundAbout™ cable exit capable (optional)
• long-life spring (100,000 full-stroke cycles minimum)
• 4-20 mA, 0-5 VDC, 0-10 VDC, ±5 VDC, and ±10 VDC signal conditioning (optional)

Typical prices for basic configurations are $96.00 for quantities of 40 and $160.00 for single units. For volume and individual orders, same day shipping is available.

Established in 1968, Firstmark Controls is an ISO9001:2000/AS9100-compliant company leading the position transducer industries with stock and engineered-to-order products.
