Monostable Rotary Magnet Type D

Rotary magnets by Kendrion Kuhnke

The rotary magnets of series D & E from KENDRION KUHNKE are suitable for applications in mechanical engineering, medical technology and laboratory technology as well as in the machine industry or in transport and traffic. The shaft, which is ball bearing on both sides, ensures precise positioning and longest service life. The rotary magnet is insensitive to linear accelerations, and is therefore used in devices in aviation and commercial vehicles.

The rotary magnets are offered in two different versions. Series D consists of rotary magnets with cylindrical cross-section. Series E offers higher efficiency due to the square cross-section with high torques in small space.

The KENDRION KUHNKE rotary magnets are available in different versions. Special versions with special applications such as plug contacts or customer-specific connector-assembled connection cables as well as modification of the shaft or customer-specific mounting holes are available on request.

Standard versions and customization options

The preferred types of the rotary magnet series are designed for 24 V DC and 100% ED. All versions are available with a rotation angle from 25° to 95°. The version BOR with shaft ends on both sides allows use as left- or right-turning version with rotation angles of 45° or 95°. The magnets are equipped with a return spring on the right-turning shaft. Depending on the size, rotation angle and duty cycle, it may be necessary to use a so-called “softly adjusted” return spring. These rotary magnets are marked with the addition DS9420 in the order number.

The coil design is preferably for DC operation with a nominal voltage of 24 V DC. In case of coil design for 205 V DC, direct operation on AC mains 230 V AC is possible via a terminal box with rectifier.

▪ Rotation angle: 25° / 35° / 45° / 65° / 95°
▪ Torque: 0.045 Ncm – 200 Ncm
