A slip clutch is a product equipped with a slip mechanism, allowing for the transmission and interruption (overload protection) of power between two rotating axes of machines or devices, as the name suggests. It transmits power when the torque is below a specified value, and when the load torque exceeds the specified value, it engages a slipping mechanism. Under normal conditions, it transmits power like a coupling, but in the event of an anomaly, it slips to protect the drive source and the product, which is a feature of the SSC-A! *For more details, please refer to the PDF document or feel free to contact us.

There are various types of clutches, including mechanical, hydraulic, pneumatic, and electromagnetic. Among them, the electromagnetic clutch we are introducing this time utilizes the electromagnetic force generated by passing current through a coil to transmit and interrupt power. It is compact, about the size of a palm, but works effectively as a power transmission and interruption device!

Many people might wonder, "The MRF device seems interesting, but how exactly is it used?" Therefore, we would like to introduce the fascinating features of the MRF device. Don't you think the movement of a typical joystick feels monotonous and unsatisfying? In response, SMT has integrated the MRF device into the joystick. By equipping the XY axis of the joystick grip with the MRF device, you can experience various tactile sensations through electrical control when you move (operate) the grip. This allows for a force feedback effect in games and simulation operations, meaning that the MRF device can provide a more immersive operating experience. *For more details, please refer to the PDF materials or feel free to contact us.

This is a case introduction page for our original product "MRF Device," which features MR fluid and offers torque control tailored to various needs. The torque changes due to the variation in magnetic force, which alters the viscosity of the internal MR fluid, enabling high quietness, agile responsiveness, and fine torque control. The MRF Device remotely provides feedback to the user regarding the pressure experienced by the machine. ★ We are currently offering a special document on the structure of the MRF Device in the catalog below!

Instead of a friction brake using friction plates, we adopt our unique coil spring brake system. Thanks to the internal clutch mechanism, there is no sliding noise during idle, which occurs with friction plate types. Custom settings for brake torque (0.05 to 0.2 N·m) are possible, accommodating a wide range of applications. It can be easily installed with just screws, eliminating the need for gap adjustments due to disassembly of parts during installation. The slip mechanism also allows it to be used as a protective device for the drive side mechanism. Additionally, forced operation during power outages is made possible by this mechanism.

Due to the tightening of the spring, it generates several times higher torque than an electromagnetic clutch, despite its small size. Its unique structure, which excels in responsiveness, allows for rapid torque rise and decay. Since it can be produced and supplied locally in Guangdong Province, China, it also significantly reduces lead times and transportation costs overseas.

• Other FA equipment

Since secondary processing (such as riveting and press-fitting) is not performed in the assembly process, there is no change in component accuracy, allowing for greater stabilization of torque accuracy than before. The incorporation of dedicated bearings ensures high durability. Local production and supply in Guangdong Province, China, enable a reduction in lead times overseas and significant savings in transportation costs.

• Other FA equipment

A series of seven models ranging from low-load, low-cost low-end models (0.147N·m) to high torque (0.49N·m). The low-end model is ideal for replacing conventional spring clutches and solenoid mechanisms due to its cost performance and space-saving design. With a design that minimizes component costs and processing fees, it is optimal for low-load, low-cost products. The SMT15AC achieves energy savings while maintaining performance with a 2.0W specification. ★ We are currently offering a special limited release of our clutch lineup materials!
