Muscle Wire - shape memory alloy metal wire (0.127mm)

DC-AC converter, also referred to as an inverter. It converts a constant voltage (DC) of 12 V to an alternating voltage (AC) of 220 V, 380 V or 18 V

The kit converts the 180 degree rotary motion of a servo into linear motion. It is ideal for use in projects requiring horizontal or vertical motion. It consists of a 5 mm thick transparent blue plate with mounting holes and an FS90 servo. Kitronik 2595

Linear actuator LACT6-12V-20 with a 15.2 cm stroke and a 20:1 gear ratio provides a force of 500 N and position stability thanks to the worm drive. The model with limit switches is intended for automation applications where feedback is not required.

Linear actuator LACT8P-12V-20 with a 20.3 cm stroke and a 20:1 gear ratio provides a force of 500 N and a feedback signal for precise position control. Integrated limit switches and a worm drive enable reliable operation in automation and control systems.

Linear actuator LACT4-12V-5 with 10.2 cm stroke and 5:1 gearbox reaches a speed of 43 mm/s with a force up to 90 N. A compact solution for applications requiring fast linear motion without position control.

A miniature linear actuator that has a stroke range of up to 130 mm at a speed of 3 to 5 mm/s. It has a built-in motor and is powered by a voltage of 3 to 6 V

30 cm nickel-titanium alloy wire with shape memory. When it is in martensitic form, it can be flexed and deformed at will. After applying a current of about 1.5A or heating to 100°C, the wire returns to its original shape. SparkFun COM-11900

Mounting Bracket for Concentric LD Linear Actuators

A miniature linear actuator that has a stroke range of up to 50 mm at a speed of 3 to 5 mm/s. It has a built-in motor and is powered by a voltage of 3 to 6 V

Linear actuator LACT8-12V-20 with a 20.3 cm stroke and a 20:1 gear ratio offers a force of 500 N and position stability without power. The model without feedback is intended for applications requiring simple but reliable motion control.

The medium-duty linear actuator can lift loads up to 100 kgf (1000 N) and withstand a static load of up to 450 kgf (4500 N), the nominal extension of the actuator is 10 cm. The power supply voltage is 12 V. This version of the actuator has a built-in potentiometer for reading the position of the actuator or, for example, feedback implementations. Pololu 3612

Linear solenoid with a nominal operating voltage of 5 V. It allows you to create a linear motion to move elements or control switches and levers. JF-0530B
