Advanced optical shutter

Based on our rotary solenoid D2, Kendrion offers a wide range of highly reliable optical shutters for blocking light and laser beams in the field of optical safety technology. The optical shutter D23 forms the technical basis with remarkable properties and can be used in a wide range of applications, e.g. in medical instruments, aeronautical instruments, fiber optic signal transmission systems and in mass photometry. The D23 optical shutter impresses with maximum reliability, durability and a fast switching time of approx. 15 ms. With at least 10 million switching cycles, the Shutter D23 is designed for reliable continuous operation.

Based on our smallest rotary solenoid D1, Kendrion offers a compact miniature shutter in the field of optical safety technology. The D16 shutter is characterized above all by its high reliability and long service life of 2.5 million switching cycles. In addition, this shutter has a fast closing time of less than 20 ms.

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

Locking solenoids of the LLV series are characterized by high forces, compact design and a lateral force carrying capacity of up to 4,000 N. The electromagnetic locking units were specially developed for use in protective devices. They are available in the versions currentless locking (CL; spring force keeps bolt in locking position) and currentless unlocking (CU; spring force keeps bolt open, locked when energized). Solenoid armature and locking bolt are guided separately in maintenance-free bearings. The latch bolt is made of stainless. The microswitch, which is installed directly in the latch housing, signals the respective position of the latch bolt approx. 0.5 mm to 1 mm after leaving the stroke start position or before reaching the stroke end position. The locking solenoids are manufactured and tested according to DIN VDE 0580/07.2000.
