Allen-Bradley 836T-T253JN18 Pressure Switch

The Allen-Bradley 836T-T253JN18 (836T-T253JN18) is an industrial pressure switch engineered for pressure monitoring and control within automated equipment and fluid handling systems. Operating within Allen-Bradley control architectures and industrial machinery, this Bulletin 836T pressure switch detects fluid or gas pressure changes and provides switching action to maintain safe and consistent operating thresholds. It functions as a critical protective and control device in pneumatic systems, hydraulic machinery, pumps, compressors, and automated industrial processing lines. Built for dependable operation in demanding environments, the switch interfaces directly with industrial control circuits, relays, and programmable logic controllers to regulate operational cycles and protect systems from overpressure or underpressure conditions. With a net weight of approximately 10 kg, the rugged unit provides stable installation and reliable mechanical performance. The Allen-Bradley 836T-T253JN18 serves as an essential direct replacement spare part for maintaining, repairing, or restoring the pressure regulation capabilities of compatible Allen-Bradley machinery and fluid processing equipment.
