Shindengen Mechatronics Co., Ltd. Product Lineup

The rotary type "Rotary Solenoid" manufactured and sold by Shin Denko Mechatronics is designed based on the flat structure and principle of our push-pull solenoids. It has a structure that converts linear force into rotational motion, making it an actuator that rotates while undergoing slight axial movement during rotation. The case and armature plate are equipped with three special inclined grooves called ball races, and between them, bearing balls are used. When a direct current voltage is applied to the coil, the suction force generated causes the armature plate to press the bearing balls strongly against the case side, allowing for instantaneous rotational movement at a fixed angle while performing axial movement due to the action of the ball races. 【Features】 ■ A solenoid that provides direct rotational motion. ■ Simple structure with excellent durability. ■ A wide range of models from small to large, allowing for selection suited to various applications. ■ Depending on the model, the rotation angles can be 25°, 35°, 45°, 67.5°, or 95° to the right or left. *For more details, please refer to the PDF document or feel free to contact us.

The "Small Rotary Solenoid OE" features a special inclined groove called a ball race, which allows it to perform axial movement while instantly rotating at a fixed angle. Due to the small gap during the rotation, when combined with a crank to convert it into a linear type, it can achieve greater force in the long stroke range compared to the linear type. It is widely used in various fields, including lab systems and industrial sewing machines. 【Features】 ■ Compact and lightweight with an outer diameter of φ20mm ■ The rotation groove is specially processed, providing nearly constant torque across all angles ■ The coil is surrounded by a high-permeability metal case, resulting in minimal leakage flux ■ The type with a return spring does not require an external return mechanism *For more details, please refer to the PDF document or feel free to contact us.

The "bidirectional rotary solenoid" is a rotary solenoid that utilizes permanent magnets. The rotational motion is achieved by the magnetic flux generated by the permanent magnet and the coil. It is widely used in various fields such as laboratory systems and industrial sewing machines. 【Features】 ■ Controls rotation in both directions by changing the polarity of the applied voltage ■ High response and high torque in both directions as it does not use a return spring ■ The sliding shaft is supported by bearings, ensuring long lifespan ■ No axial movement during rotation ■ The rotation angle can be set arbitrarily using an external stopper *For more details, please refer to the PDF document or feel free to contact us.

The rotary type "Rotary Solenoid" manufactured and sold by Shin Denko Mechatronics is designed based on the flat structure and principle of our push-pull solenoids. As a result, it has a structure that converts linear force into rotational motion, and it operates as an actuator that rotates while undergoing slight axial movement during rotation. Three special inclined grooves called ball races are provided on the case and the armature plate, and through the bearing balls in between, when a direct current voltage is applied to the coil, the armature plate is strongly pressed against the case side by the generated suction force. This allows the armature plate to rotate instantaneously at a fixed angle while moving axially due to the function of the ball races. 【Features】 ■ It is a solenoid that directly provides rotational motion. ■ It has a simple structure and excellent durability. ■ There is a wide range of models from small to large, allowing for selection suitable for various applications. ■ Depending on the model, the rotation angles can be 25°, 35°, 45°, 67.5°, or 95° to the right or left. *For more details, please refer to the PDF document or feel free to contact us.

The "Small Rotary Solenoid OE" features a special inclined groove called a ball race, which allows for axial movement while instantly rotating at a fixed angle. It is used in precision instruments such as optical shutters and laboratory systems. Due to the small gap during the rotation, when combined with a crank and converted to a linear type, it can achieve greater force in the long stroke range compared to the linear type. 【Features】 - Adopted for optical shutters - Compact and lightweight with an outer diameter of φ20mm - The rotating groove is specially processed to provide nearly constant torque across all angles - The coil is surrounded by a high-permeability metal case, resulting in minimal leakage flux - The type with a return spring does not require an external return mechanism *For more details, please refer to the PDF document or feel free to contact us.

Shindengen Mechatronics Co., Ltd. will be exhibiting at the "Techno Frontier 2026 Motor Technology Exhibition" held at Tokyo Big Sight. Shindengen solenoids can accommodate a wide range of applications with various types centered around push-pull solenoids and rotary solenoids. It is also possible to optimize thrust characteristics and operating strokes according to application requirements. Additionally, there are configurations that prioritize cost. Furthermore, we offer proportional solenoids with extremely high control characteristics and automotive-compatible solenoids that balance very high environmental resistance with low cost at a high level. We sincerely look forward to your visit. 【Exhibition Overview】 ■ Venue: Tokyo Big Sight ■ Dates: July 15 (Wednesday) to July 17 (Friday) 9:30 AM to 5:00 PM ■ Booth Number: 2-W32 ■ Address: 3-11-1 Ariake, Koto-ku, Tokyo 135-0063 ■ Nearest Stations: - Rinkai Line: Kokusai Tenjijo Station (about a 7-minute walk) - Yurikamome: Tokyo Big Sight Station (about a 3-minute walk) *Please feel free to contact us for more details.
