Spectra Symbol Featured Products

Spectra Symbol HotPot Membrane Potentiometer Sensor

Spectra Symbol HotPot Membrane Potentiometer Sensor was developed with the most rugged membrane technology and boasts over a 10 million life cycle. Robust in humidity, in temperatures up to 85ºC, and as low as -40ºC, the HotPot is an industrial, military, outdoor, and automotive preferred sensor and is ideal for door and window position sensing, as well. The Spectra Symbol HotPot Membrane Potentiometer Sensor securely bonds to the host with 3M pressure sensitive adhesive (PSA) and is IP65 rated - dust proof and water proof for intense spray.

Spectra Symbol Flex Sensor

Spectra Symbol Flex Sensor features an ultra-thin flexible substrate which operates with variable output due to the bend angle of the sensor. This Flex Sensor also features a life cycle of >1 million and withstands a temperature range between -35ºC to +80ºC. The Spectra Symbol Flex Sensor is great for finger location, gaming, robotics, and other location and bend feedback applications.

Spectra Symbol SoftPot Membrane Potentiometer Sensor

Spectra Symbol offers the SoftPot Membrane Potentiometer Sensor for universal position sensing in linear-stroke applications such as seat position, actuator position, handheld medical device location and switch, electronic musical instrumentation, and other position feedback devices. Features of the Spectra Symbol SoftPot include a 0.5mm height with lengths extending 12.5mm to 1,000mm in length. 3M pressure sensitive adhesive (PSA) securely bonds to the host and is IP65 rated - dust proof and water proof for intense spray. Spectra Symbol's SoftPot Membrane Potentiometer Sensors are currently a medical standard in the healthcare industry, as well as in many industrial applications. An inexpensive and low form-factor way to achieve full travel position sensing. Demo Video
