Package Include: 1 x Linear actuator J4 2 x Normally closed magnetic reed switch 1 x User manual Introduction: This is a linear actuator with adjustable stroke. It is equipped with two external normally closed magnetic switches that can slide freely, and by adjusting the position of these two normally closed magnetic switches, the linear actuator can be controlled to work within the set stroke length. For example, for a linear actuator with a stroke of 600 mm, you can set it to move within a stroke range of 200 mm to 500 mm. Application: It has a wide range of applications, mainly for scenes with high requirements for noise level and waterproof level. Such as water entertainment, on-water or on-board equipment, aquaculture, sewage treatment systems, outdoor electric windows and doors, irrigation devices and other water-related industrial automation equipment, household equipment and medical equipment. And it is mainly used for doors, windows, cellars, trapdoors, hatchways, solar tracking system, medical devices, agricultural machinery, vehicles, ships, elevator platforms, lifting tables, TV lifts, robots, cabinets, massage sofas, electric beds, medical chairs, and other electrical equipment. It can open, close, push, pull, lift, and descend these devices. It can replace hydraulic and pneumatic products to save power consumption. Feature: High-quality products and high-quality services New housing design, high working stability Metal housing, able to work in very harsh environments Metal gearbox, high strength wear-resistant gear Aluminum alloy telescopic tube and outer tube, good corrosion resistant Heavy duty design, high-power DC motor Worm gear structure design, strong self-locking force POM engineering plastic worm gear, low noise Advanced waterproof and dustproof technology With waterproof breather valve, ideal for use outdoors or in the rain. Low power consumption and low noise Equipped with two external normally closed magnetic switches that can slide freely, by adjusting the position of these two normally closed magnetic switches, the linear actuator can be controlled to work within the set stroke length. You can control this linear actuator by a remote switch. Built-in two limit switches, linear actuator will automatically stop when stroke rod reaches the limit position. With auto-locking capability to hold load position after stopping, and no power supply is required. Maintenance-free Specifications: Optional working voltage: Optional working voltage: DC 12V, DC 24V Stroke: 28 inches or 700 mm Optional speed: 5±1mm/s, 10±2mm/s, 16±3mm/s The above is the speed at no load, and the actual working speed will gradually slow down as the load increases. Max load capacity: 3500N / 350 Kgs / 780 lbs at 5mm/s Linear actuator can get maximum load capacity when it operates in the vertical direction, and the pulling force is less than pushing force. No-load current: 0.5~1A at 12V or 0.3~0.5A at 24V Full load current: 7A at 12V or 3.5A at 24V Please use a 12V/10A or 24V/5A power supply to power the linear actuator Shaft diameter: 20mm The diameter of the mounting holes for the front and rear connectors: 8mm [0.315 in] Housing material: Aluminum Alloy Stroke rod material: Aluminum Alloy Gear material: POM engineering plastic + Steel Alloy Motor type: Brushed DC Motor Duty cycle: 20%, max 5mins continuous use Service life: approx. 25,000 cycles Power cable: Ordinary Two-core Wire Cable length of the linear actuator: 1000±10%mm [40 in], the length can also be customized according to your specific needs. Certifications: CE Environment temperature: -20℃ to 80℃ Operating noise: ≤45dB (Linear actuators with different parameters will have different noise levels.) IP rating: IP67 (Ideal for use outdoors or in the rain, but it is not suitable for use submerged in water.) Different no-load speeds and corresponding maximum thrust No-load Speed Full load Speed Maximum Thrust Self-locking Force 5mm/s 3mm/s 3500N / 350 kg / 780 lbs 3500N / 350 kg / 780 lbs 10mm/s 5.5mm/s 2500N / 250 kg / 560 lbs 2500N / 250 kg / 560 lbs 16mm/s 8.5mm/s 1500N / 150 kg / 340 lbs 1500N / 150 kg / 340 lbs Wiring for remote switch: If use a remote switch to control the linear actuator, do as following: 1. Connect two wires of DC power supply to two terminals of the remote switch input. 2. Connect two wires of linear actuator to two terminals <Motor> of the controller, and you can exchange these two wires to change the moving direction of linear actuator. 3. Connect two magnetic reed switches to the limit control terminals of the remote switch, please follow the connection diagram below for specific wiring. Operation by remote switch: 1. Press and hold the button ▲ on the remote: linear actuator extends outward, when it moves to the position of a magnetic switch, the linear actuator will automatically stop. 2. Press and hold the button ▼ on the remote: linear actuator inward retracts, when it moves to the position of another magnetic switch, the linear actuator will automatically stop. How to adjust the position of the magnetic switch: You can loosen the fixing straps of the magnetic switch, then move the magnetic switch to a suitable position and tighten the fixing straps again. Note: If the positions of the two magnetic switches are reversed, please swap their positions. Production time: The linear actuators are the customized products, and these products are not in stock, we need to spend 3~7 working days to produce them according to the specified parameters in your order. Return or Exchange: The Linear Actuators are the customized products, we need to produce them according to the specified parameters in your order, so that we do not accept returns or cancel orders. If customers order unsuitable linear actuators themselves, we also do not accept exchanges, please understand.
