SM300 Compact Silent Linear Actuator 12V 24V DC 3000N for Electric Sofa Medical Bed, Hall Sensor Optional
Linear Actuator
SM300 is a compact low‑noise DC linear actuator, specially designed for applications with limited installation space such as electric sofas, recliner chairs and medical nursing beds. It works under 12/24 VDC, delivering max push force 3000 N and max pull force 2000 N, with low operating noise ≤52 dB.
No‑load speed ranges 5‑25 mm/s and full‑load speed 3‑15 mm/s at 10% duty cycle. The minimum installation dimension is S+130±3 mm. Hall sensor is optional for position signal feedback. Note: the current will approximately double when operated at 12 V.
Multiple motor options (standard / fast / heavy‑duty motor) are offered with various force and speed grades. Widely used in home furniture, medical rehabilitation equipment and small‑scale industrial linear motion projects.
The SM300 is an L‑shape compact low‑noise DC linear actuator, engineered for furniture and medical equipment with limited internal installation space.
It is widely applied to electric sofas, recliner chairs, massage chairs, nursing beds and compact industrial adjustment mechanisms.
Operated at 12 VDC or 24 VDC, it delivers maximum push force up to 3000 N and pull force up to 2000 N. The no‑load speed ranges from 5‑25 mm/s, full‑load speed 3‑15 mm/s with 10% duty cycle. Operating noise is ≤52 dB for smooth and quiet performance, ideal for indoor furniture and medical devices. The minimum installation dimension is S+130±3 mm. Its side‑mount L‑shape motor design saves valuable space inside end‑products.
Built‑in mechanical end‑stop protection ensures safe operation. Hall‑effect sensor is optional for position feedback signal, supporting precise positioning and multi‑actuator synchronous control. Please note that operating current will approximately double under 12 V power supply.
Three motor variants are available: standard motor (2200RPM), fast motor (3800RPM) and heavy‑duty motor (3400RPM). Seven model codes from A‑G cover force range 500‑3000 N with different speed performance. Robust aluminum alloy construction with self‑locking function holds position securely upon power loss. Custom stroke lengths are supported to satisfy diverse linear motion requirements for home furniture, medical rehabilitation and compact industrial automation.
Applications: Electric sofa, recliner chair, massage chair, nursing hospital bed, elderly‑care rehabilitation equipment, small‑size industrial lifting & adjustment mechanisms.
