Seller: shedbuilderuk (516) 100%, Location: Cambridge, Ships to: GB, Item: 283007074666 These are high-quality Linear Actuators that were originally designed for use as "cruise controls" for agricultural vehicles. They are new and unused, but have been dry stored for a few years (Which is why I've listed the condition as "New other"). Their unique feature is that they include an electrically operated clutch that allows the output arm to be mechanically disconnected from the drive system. The unit also contains a linear potentiometer that allows the position of the output arm to be sensed. Their case is a very solid aluminium die-casting, and internally they have a high quality gear-train. I use these units in conjunction with Arduino microcontrollers and inexpensive L298N boards (available from eBay for around £1.50) to make mechanical drives for various projects. They have proven to be both reliable and powerful. The nice thing about the using the L298N boards is that they have two output channels, so one channel can be used to drive the motor, with the second driving the clutch. The potentiometer can feed directly into the Arduino's A/D converter, and with a bit of Arduino code, you've got a very powerful and inexpensive servo. To get you started, I'll include a printed description of how to get the actuators up and-running with an Arduino and a L298N board, though if you know some electronics you'll be way past that in no-time. The actuators are ideal for home automation projects, greenhouse window openers, automotive, etc. The units are 95mm x 72mm x 75mm (excluding the mounting studs), and have a stroke of 50mm. The end-to-end travel time is less than three seconds. Both the clutch and motor are rated at 12 volts. The clutch draws a around 120 mA when energised, and the motor around 500 mA while running under reasonably heavy load. I haven't measured how much physical push-or pull there is, but it's a lot (way way more than I can resist with my hand). I have a quantity of these, so please contact me if you require multiple units. Condition: New other (see details)
