Question 1

What are bi-stable rotary solenoids used for in automatic sorting systems?

Accepted Answer

Bi-stable rotary solenoids are electromagnetic actuators that enable high-speed, highly durable conveyor path switching and product ejection in automatic sorting machines. They rapidly distinguish between product quality, shape, and size, and accurately perform sorting of good/defective products and grading by size. Takano's rotary solenoids provide space-saving solutions with low power consumption and exceptional responsiveness.

Question 2

Why are Takano rotary solenoids ideal for defective product ejectors?

Accepted Answer

Takano rotary solenoids are ideal for defective product ejectors because they combine high-speed responsiveness with durability to withstand long hours of continuous operation. Their bi-stable magnetic technology requires power only when the blade rotates, making them energy-efficient. With life cycles exceeding 5 million cycles and response speeds as fast as 8 milliseconds, they reliably handle demanding sorting applications.

Question 3

What selection criteria should be considered when choosing a rotary solenoid for sorting applications?

Accepted Answer

When selecting a rotary solenoid for sorting applications, consider: (1) Response speed—faster actuation improves sorting throughput; (2) Durability—life cycle ratings must support continuous operation; (3) Size and weight—compact designs save space in machinery; (4) Power consumption—bi-stable technology reduces energy costs; (5) Operating angle and force requirements—must match your conveyor switching or ejection mechanism specifications.
