Curtis PB-6 Style Throttle 0-5k 3-Wire PB-8 Compatible

Description
· Same physical shape as the PB-6, as well as the same mounting pattern · 3 terminal safety microswitch which may be used for various control inputs · Stainless steel case with spring return lever · Output: 0 - 5K ohm wiring: POT HIGH = BROWN WIPER = BLUE POT LOW =WHITE or BLACK The standard controller throttle input is 0–5kΩ. Curtis potboxes (PB-5, -6/8, -9, -10) are designed to match this input. Some of these potboxes have a built-in safety microswitch, eliminating the need to install a separate pedal-actuated safety microswitch. Curtis also offers a self-contained foot pedal unit (FP-2) that eliminates the need for fabricating and installing a pedal-potbox linkage. Any potbox that provides a nominal 0–5kΩ output (controller output begins at ≈300 ohms, full output is ≈4400 ohms) will work with the standard throttle input. The pot box must be mounted so as to allow connection between the potbox lever arm and the vehicle accelerator linkage. The mounting dimensions are shown in Figure 3. The lever arm provides a series of holes so that the accelerator pedal “throw” can be converted into the correct amount of potentiometer rotation. Use of a second return spring on the pedal, in addition to the potbox return spring, is required to prevent an uncontrollable full-on throttle input (which could happen if there was a single spring, and it broke). If the self-contained potbox spring is insufficient to return the pedal by itself, two additional pedal return springs must be used. It is also required that the accelerator pedal hit a mechanical stop at its full-on position just before (≈1 mm [1/32"–1/16"]) the potbox lever hits its own full-on stop. This mechanical stop will prevent the potbox lever arm from bending if undue force is put on the pedal. Protection of the potbox from water and dirt will help avoid problems of corrosion and electrical leakage. After the potbox has been mounted, operation of the pot can be tested by measuring the resistance between the two wires with an ohmmeter. With the pedal not applied, the resistance should be less than 50 ohms. As the pedal is applied, the resistance should rise smoothly until it reaches a value between 4500 and 5500 ohms. Values below 4500 ohms may cause a reduction in efficiency and top speed. Values above 7000 ohms indicate a defective potbox, and will cause controller shutdown. The potbox is the throttle in an EV. It tells the controller how much current is needed to be sent to the motor. The potbox's lever arm is attached to the existing accelerator cable. The box translates foot pressure into a variable resistance to let the controller know how fast you want to go. In addition there is a safety switch inside that helps prevent starting the EV with the gas pedal floored. 0-5K Resistance with Micro Switch for Contactor Control. Dimensions: 3-3/4" high, 4" long, 2-1/16" deep
long time to deliver? but fit was good the item was delivered straight from China vs sellers' location, this was probably 8-10 bucks in China and delivery was too long and cost too high looking at where it came from, also no mounting screws that i had to go purchase? would not recommend this seller. i would have ordered direct from Temu
I am revising my feedback. Since I was not able to use the golfcart charger handle, the seller refunded all of my money (including the shipping cost). I did not expect the seller to provide a full refund. I am very pleased with what they did. I highly recommend them to anyone. I thank them for their very positive action.
This was and exact fit for my bad buggy as advertised! It was obviously in new condition, good quality, and was a good value! This seller also provided excellent communication and customer service. I highly recommend this seller!
