Applications: Angle and Position Measurement with Encoders in Harsh Environments

We are receiving an increasing number of inquiries like the following.

There is an increasing demand for digital data acquisition of angles and positions by combining a general-purpose incremental encoder with a measuring instrument.
The SPD series has an automatic measurement transmission function (USB and CAN) to help customers reduce program development time.

- Both digital and analog output of angle and position
- Utilize the high detection accuracy of optical encoders in harsh environments
- Need a rotary angle sensor with both high resolution and environmental resistance?
- Need a space-saving design equivalent to IP65-67.

How about these products (encoders)?
- Protection class IP65: No need for a protection case, cost reduction, easy installation, and more mounting options
- Hollow type (through-hole shaft) also available: High-precision measurement with small mounting error and space-saving installation.
- High resolution: Various pulse rates from 360-144,000 P/R available
- Excellent robustness: Metal pulse disk for high shock and vibration resistance
- Wide temperature range: High temperature characteristics and photo IC with automatic light intensity compensation are standard. Stable output from -20°C to +85°C.

Selection Points
-　IP65 rating, less susceptible to adverse effects caused by foreign substances (dust, water, oil) entering from the outside.
-　No case cover for encoder protection is required, which reduces the cost of the machine.
-　Easy acquisition of measured values in digital format using the CAN continuous output function (depending on the selected model)

Improvements
　Conventional
　- Encoder: Drip-proof type requires larger encoder body dimensions and more space for installation
　- Encoder: Fewer types of hollow-type (through shaft) drip-proof products available, limiting choice.
　- Measuring instrument: Measurement data acquisition by command response method

　Improvements
　- Encoder: Compact, lightweight, and dust-proof and drip-proof performance, providing more choices of installation locations and enabling highly efficient design.
　- Encoder: Hollow shaft and high resolution enable feedback detection of highly accurate rotational angle position of the machine.
　- Measuring instrument: Automatic output of measurement data at each update time reduces program development costs (depending on selected model).

Applications - Detection of rotational angle position of machine arm section
- Detection of rotational feed pitch and rotational speed of conveyor transfer section
- Measurement of rotation angle and rotation count of driven ball screw mechanism part, etc.
