OTTO J3 Transducer Range Details

Part of the OTTO Transducer Switch Series, these J3 Transducers provides analog output proportional to the force applied to the button. OTTO J3 Transducers features a short, concave pushbutton to deliver precision control. KEY FEATURES • Force Transducer Switches • Custom Options • IP67S or MIL-PRF-8805, Symbol 2 OTTO J2 Transducer Switches offer short travel with full bridge circuit type & an impressive 1,000,000 cycle life.


The J3 series of strain gauge based force transducers provides analog output proportional to the force applied to the button. The J3-100002 bottom mount transducer offers short travel, full bridge circuit, a concave button style and 1 million cycle life.

The strain gauge technology compensates for outside influences, like temperature, allowing the transducer to maintain accuracy even in the most demanding environments. 

OTTO J3's threaded bushing case offers a secure switch retention method for a wide range of panel thicknesses. Applications include flight control of aircraft, operating ground vehicles, and cursor control or target acquisition.
