No Contamination. The OP series has been designed to provide fast response. Response rates can be further quickened through overexcitation circuits. The OP series unit's sturdy construction and precise formulation of themagnetic particles combine to provide extended life. SlipCapacity. Magnetic particle clutch designed for industrial applications requiring fast response time and a stable torque. Units can also be set for continuous slip which makes them ideal for tension applications. Since voltage to torque is linear, output torque can be easily controlled. Since torque is also transmitted via internal particles, unit life is extremely long. Units are sealed which prevents any wear particles from contaminating the machine, and also prevents contamination of the clutch by the machine environment. Stable Torque. The OP series produce consistent and repeatable torque. Torque is independent of speed and proportional to voltage applied to the field. Fast Response. Long Life. OP series units are designed to deliver high performance under constant slip conditions.
