Product overview
The KST A15-1812 is an aircraft servo with a case measuring 35.5mm × 15mm × 32.5mm, subject to a dimensional tolerance of ±0.2mm. Its specified weight is 42g ±10%. These case dimensions and weight provide physical parameters for integration planning. The servo has a rated operating voltage of DC7.4V and an operating voltage range of DC6.0V–8.4V. Its operating temperature range extends from -20°C to +65°C, defining the stated temperature limits for operation.
At 7.4V, the A15-1812 delivers a rated torque of 0.5N.m and a stalling torque of 1.8N.m. Its rated speed is expressed as 0.18 seconds per 60° of movement; the no-load speed is 0.12 seconds per 60° at the same voltage. Travel depends on the input range: 1000us–2000us corresponds to ±50°, while 500us–2500us corresponds to ±100°. The two travel specifications therefore retain distinct input conditions, just as the speed specifications distinguish rated operation from no-load movement.
