A supply is included only in the two supply packages; the explicitly identified adapter is 5 V upstream of the controller. A controller does not by itself establish a new motor voltage rating. Do not connect a 5 V adapter directly to the 3.7 V motor; configure the supply\/driver arrangement within the motor rated limits.\u003c\/p\u003e\u003ch2\u003eConnection and Mechanical Installation\u003c\/h2\u003e\u003cp\u003eUse a suitable DC motor driver and supply arrangement for the 3.7 V motor, with startup-current capacity and overcurrent protection. The motor-end illustration marks positive and negative terminals. Reverse the motor leads when a change of rotation is required, while keeping controller power-input polarity correct. Never connect household AC directly to the actuator or controller.\u003c\/p\u003e\u003cp\u003eConnect the actuator to the controller motor output and the supply to its marked DC input. Inspect the actual board and adapter labels before connection. The knob adjusts the illustrated controller output setting; exact controller electrical ratings are not separately specified here.\u003c\/p\u003e\u003cp\u003eAlign the actuator and keep side loads off the moving output. Allow the entire 77–85 mm reference envelope, guard the moving end and avoid mechanical blocking or impact. Do not treat the actuator as a feedback-controlled positioning axis or a certified load-holding mechanism. Avoid prolonged stall, overheating and moisture.\u003c\/p\u003e\u003ch2\u003eApplications\u003c\/h2\u003e\u003cp\u003eSmall reciprocating mechanisms, compact motion demonstrators and integration projects requiring repeated short linear travel. Validate actual thrust, speed, duty cycle and mounting for the application. General rotary load\/lever illustrations do not establish a payload rating for this assembly.\u003c\/p\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cp\u003eOne selected SP 20-180 actuator and only the accessories named in the package. Power supply, bracket and controller are not universal inclusions. Complete equipment, external limit sensors, encoder, battery and extra loose internal components are not included.\u003c\/p\u003e\u003ch2\u003eFAQ\u003c\/h2\u003e\u003ch3\u003eIs the rated motor voltage 5 V?\u003c\/h3\u003e\u003cp\u003eNo. The motor reference is 3.7 V. A 5 V adapter in a package is an upstream accessory and must not be treated as a direct motor connection.\u003c\/p\u003e\u003ch3\u003eIs the travel exactly 10 mm?\u003c\/h3\u003e\u003cp\u003eThe technical table and 77–85 mm dimension envelope give approximately 8 mm. Use this reference and check the actual assembly before fitting.\u003c\/p\u003e\u003ch3\u003eDoes the 600 cycles\/min option give the same loaded performance?\u003c\/h3\u003e\u003cp\u003eNot necessarily. Cycle rate, current and thrust depend on the selected version and operating conditions.\u003c\/p\u003e\u003ch3\u003eDoes every option include a bracket?\u003c\/h3\u003e\u003cp\u003eNo. Only packages
