Adjustable Travel 12V DC Rack & Pinion Linear Actuator, Gate, Door, Slider Motor
(Steel 1.5 MOD) 2pc. (Including 4pc M5 screws with a 3mm hex-socket size, for attaching one rack to another) 1pc.
Each limit trigger plate (as the plastic blocks are called) is fixed to a rack section with two M4 screws, each with a 2.5mm hex-socket head. The transparent side of the actuator body reveals the orange switch plungers and where the trigger plates engage with them, allowing extension adjustments to be made visually, as shown below. To increase the travel distance of the actuator you can simply remove one of the two limit plates, attach an additional rack section using one of the two included clamping sets (ensuring that the button-heads of the clamping screws are on the transparent side of the actuator body), and then replace the removed limit plate onto the new rack where you would like the actuator to stop. An example of two racks attached to one-another, alongside one of the clamping sets, is pictured below. An'adjustments guide' leaflet is included with each actuator to guide you through the process of adjusting the travel limits and adding additional racks, a copy of this is available here.Both ends of the steel rack sections have two 5mm holes (used for the clamping plates) and one 6mm hole, which can be used to transmit the load, via a pivoting bracket. By pulling on a cable, or similar. The included aluminium slot-bracket is designed to fit either of the two 6mm mounting holes on the main body of the actuator, to allow the body to pivot as the rack extends and retracts. Nominal 12V DC, up to 60W. 15% this is the maximum proportion of time that the actuator may be in operation for, up to 2minutes during any continuous stretch. The duty cycle should be reduced below 10% for average loads >200N. Please be aware that there may some variation in the operating performance from actuator to actuator, as a rule-of-thumb allow for a 5% difference above/below the given values.
If intending to use two actuators together to drive the same assembly connect them in parallel to the input current and ensure that the driven assembly is rigid enough to transfer forces between the actuators (so as to prevent twisting if one actuator is slightly faster than the other). Two sets of 6mm through-holes for pivoting mounts and hinged brackets. Three M5 tapped holes for flat-surface mounting. Only fix the body with these (so that it cannot pivot) if the load is perfectly linear and parallel to the moving rack One 6mm and two 5mm holes at the end of each rack section. Polycarbonate (transparent side), Delrin (black side and internal features), with aluminium gearbox housing.Hardened carbon steel, with black oxide treatment. It is recommended that oil is applied to the racks and clamp pieces every 4 months or so, this is not needed for mechanical lubrication but will help defend against corrosion (particularly in higher humidity environments). Wiping along the racks with an oiled rag should be sufficient for this purpose. For a dimensioned diagram (jpg image) for both rack sizes.
