KUHSE Twin brake release actuators

Product catalog summary

Design and Specifications
The GSd series twin brake release actuators are designed with diameters ranging from 99 mm to 164 mm and stroke lengths between 2.5 mm and 4.0 mm. These solenoids offer higher rated forces compared to the GS series of similar diameters. The armature movements are performed by electromagnetic force, requiring an external power source (spring or weight) for resetting.

Technical Data
The GSd series includes types 100, 115, 135, 136, and 165, with maximum strokes ranging from 0.25 cm to 0.4 cm. The relative on-time (ED) varies between 40% and 100%, with starting forces from 255 N to 1350 N and holding forces from 540 N to 2700 N. Power consumption ranges from 30 W to 170 W, with attraction times between 270 ms and 645 ms, and drop-out times between 120 ms and 280 ms. The total weight varies from 8.0 kg to 44.5 kg, with armature weights from 0.9 kg to 3.8 kg. The standard degree of protection is IP 42, with IP 54 available as an option. The preferred rated voltage is 200 V DC, with other voltages available upon request.

Dimensions
The dimension table provides detailed measurements for each type in the GSd series, including parameters such as diameter, length, and mounting specifications. Accessories like levers and pressure springs are available at extra cost, and special requirements can be accommodated upon request.

Design Expanding solenoids of model range type GSd are produced in sizes of 99 mm to 164 mm diameter, and with stroke lengths between 2,5 mm and 4,0 mm. So, these solenoids are featuring higher rated forces as compared with solenoids of type GS of similar diameters. The armature movements from stroke starting- to stroke limitpositions are per formed by electro magnetic force; for resetting, an external power source (spring or weight) is needed. GSd
