Mechanical Position Sensors

Angular position sensors, linear sensors, and tilt angle sensors all have a wide range of applications in the automotive industry. These sensors can be used to detect steering wheel positioning, pedal position sensing, headlight position control, and also has extensive use in robotics.

Position Sensors

These are precision sensors that convert mechanical displacement such as rotational angle, tilt angle, linear displacement, and pressure variance into electrical signals. Midori potentiometers have very low current consumption and are available with a contact element or without. With Hall effect type of contactless potentiometers, there is no electrical noise in the output and are ideal for a harsh environment where there is vibration or dither because of low amplitude. Conductive plastic and Wire-wound Multi-Turn potentiometers have virtually infinite resolution.

Applications:

  • Electric Locomotive: Speed control lever  
  • Crane, Aerial Work Platform: Boom/Arm swing angle
  • Automotive Inspection Equipment: Steering wheel rotation angle
  • Wind Power: Wind direction, Blade angle
  • Automated Guided Forklift: Steering angle
  • Injection Molding Machine: Press stroke
  • Winding Machine: Tension & Speed control
  • Valve Positioner: Valve position
  • Flowmeter: Flow regulating valve
  • Electrical Microscope: X-Y axis position
  • Industrial Joystick: Manipulation angle position
  • Personal Transporter: Speed controller
  • AGV: Wheel angle
  • Wearable Robot: Joint angle of robot arms/ legs

Linear Potentiometers

Hall-IC type contactless and with Conductive plastic contact type Linear Potentiometers. There is no electrical noise in the output, low torque, low friction, and superior lifetime. Conductive plastic Liner Potentiometer has a practically infinite measurement resolution with even higher precision compared to contactless type. Available in very small measurement increments and lengths.

Applications:

  • Railroad Switch: Point blades position
  • Bending Machine: Foot pedal
  • Dam: Crack monitoring
  • Fork Lift: Electric power steering
  • Driving Simulator: Control lever position, Foot Pedal Angle
  • Pneumatic Needle Valve: Valve position
  • Bending Machine: Material Position Control
  • Car Inspection Machine: Wheel Alignment
  • Injection Molding Machine: Mold clamping stroke
  • Pesticide Spraying Vehicle: Supply valve aperture
  • Tractor: Hydraulic cylinder stroke
  • Race Car: Monitoring torsional and flexural of the body
  • Injection Molding Machine: Mold clamping stroke, Adjust the amount of liquid resin injection

Inclinometers and Tilt Sensors

Single axis and dual axis (X and Y axis) analog output Inclinometers and Tilt Sensors can use pendulum mechanism or a buoy-flat mechanism. These are sealed with a damper oil for optimum vibration control and response time and can be used for very narrow tilt angle measurement. Midori also offers MEMS sensor type devices which can be reconfigured or programmed to your specific Electrical Angle, Tilt Angle, Index Point, and Response Time. The MEMS devices also have superior temperature characteristics and high resistance to vibration thus making them ideal for harsh environments.

Applications:

  • Fish Finder: Tilt control
  • Medical Treatment Bed: Reclining angle
  • Truck: Rear Loader
  • Leaderless Pile Driver: Vertical position of drill    
  • Maritime Satellite Antenna: Antenna position
  • Crane, Aerial Work Platform: Boom angle, Jib angle         
  • Excavator: Body attitude              
  • Conveyor: Conveyor angle
  • Dam Gate: Gage angle
  • Ferry Ship: Vehicle gate angle
  • Shield Machine: Pitch & Roll position      
  • Bulldozer: Body attitude              
  • Power Seat Test Equipment: Seat position & angle

Whether you have a need for an angle sensor, linear sensor, or tilt angle sensor, the products provided by Midori America Corporation are designed to not only meet the exacting industry standards that so many business sectors expect, but are also designed to be as durable, functional, and precise as possible.

Midori America Corporation is a wholly owned subsidiary of Midori Precisions Co., Ltd, a Japanese company founded in 1952. Midori Precisions Co., Ltd. originally developed and manufactured electromechanical transducers to be used in the myriad electronic businesses that dotted the Japanese business landscape. These early products were created by using the same wire-wound potentiometer technology that was to be offered in the precisions instrumentation market. By the early 70s, Midori Precisions Co., Ltd. had developed technology that was able to provide its product line with precision conductive plastic instruments. The 1980s saw even more success for Midori as they pioneered a new form of technology, the contactless magneto-resistive potentiometer. Based upon this technology, Midori was able to offer a sensing element offering with improved function and cost efficiency to industries across the world.

Midori America Corporation, as a sales and factory representative of Midori Precisions Co., Ltd., is dedicated to providing the American market with the best in position sensors including plastic linear and rotary potentiometers and contactless linear and rotary potentiometers. All products are made to the exacting standards that made Midori Precisions Co., Ltd. a respected name in the Japanese industrial sector and you can rest assured that all of your needs will be met by these products.
