The 836T-T260JX40 controller is an 836 Pressure Controls tool made by Allen-Bradley. It is a traditional machine tool used by different industries to detect and monitor pressure levels. It is used in air compressors, machine tools, and hydraulic devices. It features snap action precision switches that are equipped with silver contacts that help with friction-free and consistent performance. The controller comes with operator-adjustable operating and differential pressure ranges. The operating range of the pressure controller ranges from 30 inches of mercury in a vacuum to 35 PSI. The front side has a blank label which can be used to write important operation information on. The external bellows of the pressure controller are manufactured using copper alloys. The controller uses a ¼-inch NPT female pipe connector. It supports a maximum line pressure and occasional surge pressure up to 65 PSI. The surge pressure is the maximum pressure that can be applied to the actuator. Surges or transients may occur during the startup and shutdown of the system. 

The Allen-Bradley 836 series 836T-T260JX40 pressure controller uses a ⅜-inch NPT female pipe connector for the piston. The piston unit has an adjustable operating pressure range. The 836T-T260JX40 controller can be used with both open and closed circuits and it can respond to both pneumatic or hydraulic pressure. When pressure is applied to the actuator, it exerts force on the main spring. When the threshold pressure of the spring is reached, it transfers the motion to the contact block which in turn causes the tripping. The pressure control unit has a toggle spring mechanism that is efficient. The 836T-T260JX40 controller has a temperature range between -30 and 66 degrees Celsius for regular operation and it can be stored at a temperature range between -30 and 93 degrees Celsius when not in use.
