LEP Product Introduction:
The LEP brushless waterproof and dustproof displacement sensor is composed of two carbon film substrates, with a hollow separation between the two. On the carbon film substrate, advanced technology and process of screen printing are used to process conductive materials for potentiometers. The collection carbon film foil directly above the substrate is printed with low resistance collection sensing materials; The external force applied by the external position contact makes the sensing material of the collection membrane come into contact with the conductive material of the potentiometer, thereby generating real-time displacement signals. The dedicated screen printing coating and several continuous linear lithography processes of the lithography machine can ensure excellent linear accuracy and long lifespan of the sensor.
LEP Features:
● Flat carrier, long service life, high resolution, high stability, and excellent materials
● Prevent the intrusion of stains, dust, and liquids
● Excellent linearity, up to ± 0.05% FS
● The shell is made of hard anodized aluminum oxide, which is beautiful and elegant. The protection level is IP67, and the working temperature is high
LEP Application Field:
Medical equipment specific, robot system, valve actuator, solar panel position control, car and truck adjustment, window lifting, folding convertible roof, mirror system, etc.
