About us

Sentech was founded in 1988 by an entrepreneurial couple who wanted to create a company that was focused on designing and manufacturing world class sensors for the most demanding and critical industries. They took this mission and made it a success through hard work and close collaborative relationships with their customers. Job one was to intimately understand each customer’s unique requirements.  

Since then, Sentech has become a leader in designing custom electromechanical sensing and actuation products for Industrial, Aerospace and Military markets.  Designing for mission-critical applications, Sentech has proven to be the primary source for many of its loyal customers.

Sentech is a global leader in the design and manufacture of position, proximity and speed sensors, including Linear Variable Displacement Transformers (“LVDT”), Rotary Variable Differential Transformers (“RVDT”), Hall Effect, Variable Reluctance, Signal Conditioners, and Solenoids.

Sentech is a valued supplier of sensors to customers across the globe for both standard and custom solutions for critical position and speed applications.

We are privately owned and proudly manufacture in the USA in our facility in Willow Grove, Pennsylvania, outside of Philadelphia. Importantly, we are certified according to the most stringent industry standards including ISO 9001, AS9100D, UL/CSA, ATEX, IECEx, TIIS, and KOSHA among others.
