Industrial SP75S-MF1-4-1E1-2S Industrial Automation Proximity Sensor

The SP075S-MF1-4-1E1-2S from WITTENSTEIN alpha is a compact, single-stage planetary gearhead that delivers a 4:1 reduction for precise torque multiplication in servo-driven automation. The output shaft end is supplied with a key (con chaveta) for secure coupling, and the gearhead’s inertia is 0.780 kg·cm², supporting predictable acceleration and load response. Drive data lists an S1 (continuous) input speed of 2,900 rpm and an S3-60% (intermittent) input speed of 7,500 rpm, with corresponding output torques of 81 Nm at S1 and 132 Nm at S3-60%. The SP075S-MF1-4-1E1-2S designation denotes one planetary stage and a 4:1 transmission within the MF1 family, reflecting its intended use in compact drive assemblies that require reliable speed reduction and torque amplification. This gearhead is designed for robust operation in industrial environments where stable, repeatable motion is essential.
