Company Overview
The Fredericks Company is an ISO 9001:2008 certified company founded in 1935. Our facility is located in Huntingdon Valley, Pennsylvania and we are a leading designer and manufacturer of electrolytic tilt sensors and inclinometer assemblies. Because we design and manufacture both the core electrolytic sensing technology and the completed inclinometer assembly at our facility, we maintain full control over the production process of our units. This ensures quality from unit to unit and eliminates any problems associated with parts obsolescence. Electrolytic tilt sensors manufactured at our facility have performed reliably in the field for many years, testifying to the quality of our workmanship.
The long history of The Fredericks Company provides assurance that we will continue to support and manufacture our products in coming years; we also guarantee support of our products for as long as they are being used in our customers’ products and the raw materials remain available. Our skilled engineering team has decades of combined experience and can provide in depth implementation recommendations upon request.

Electrolytic Tilt Sensors – General Information
Electrolytic tilt sensors from The Fredericks Company provide high accuracy angular position measurement in one or two axes. These sensors require signal conditioning circuitry to provide an angular output. The Fredericks Company offers a variety of low cost signal conditioners to run our electrolytic sensors. Customers can also design their own signal conditioning circuitry; TFC can provide circuit and software design input and analysis upon request.

Inclinometers – General Information
Inclinometers are an assembly of a signal conditioner and tilt sensor. The assembly provides an output of tilt position in one or two axes through a variety of standard interfaces. Our inclinometers utilize either electrolytic or MEMS technology to sense tilt angle. A regulated power input is available as well as potting for all housed units. Potting provides an environmental protection rating of IP67.

Tilt Switches – General Information
Tilt switches provide an on/off indication of whether the unit is tilted past a certain angle which is field programmable. The type of output and availability of communications is dependent on the unit. All tilt switches utilize an electrolytic tilt sensor and signal conditioner. They are also enclosed in an ABS plastic housing with potting to provide an environmental protection rating of IP67. They also include a regulated power input.
