Compact Optical Shutters

Based on our portfolio of rotary solenoids, Kendrion offers a wide range of highly reliable optical shutters for light and laser beam blocking in the field of optical safety technology.  Our optical shutters are used in a variety of applications, for example, in medical instruments, aerospace instruments, fiber optic signal transmission systems, and mass photometry.

Miniature shutter

The D1 miniature shutter is particularly suitable for space-critical applications. Despite its small size of 15 mm, it is characterized by its high reliability and long service life of 10 million switching cycles. The miniature shutter also has a fast closing time of less than 20 ms. Due to its simple control, the D1 shutter is suitable for a variety of applications for interrupting light beams.

High-performance shutter

The D2 high-performance shutter combines a solid construction designed for maximum reliability and durability. The shutter has a fast switching time of about 30 ms. With at least 10 million switching cycles, it is designed for reliable continuous operation. Besides, the integrated photocells enable the switching position to be detected. The bounce effect is optimized by using an integrated damping mechanism.

Bistable shutter

Based on the bistable rotary solenoid CDR030, Kendrion offers a bistable shutter that enables currentless holding in both end positions. The end positions are held by the built-in permanent magnets. This makes the magnet design very energy-saving. The CDR030 shutter is also characterised by its high reliability and long service life of 20 million switching cycles. In addition, the shutter has a typical closing time of 30ms.
