Allen-Bradley 836-A1A Pressure Control Type 1 Enclosure

Allen-Bradley 836-A1A Pressure Control Type 1 Enclosure is a Bulletin 836 pressure control switch configured for panel mounting in general industrial equipment. This device style A unit uses an internal copper alloy bellows sensor and ships with no enclosure modifications required, making it compatible with standard Type 1 enclosures used inside electrical panels. The associated 836-A1A cut sheet lists a control-circuit rating of AC 125 VA and voltage compatibility from 24 to 600 V, enabling straightforward integration with common control circuits and power supplies. Designed for reliable automatic pressure control in pneumatic or hydraulic systems, this enclosure-ready switch provides switching action at user-programmable setpoints within the 836 family’s range while keeping the sensing element protected from environment inside the panel. Its rugged metal enclosure and Style A bellows support stable operation in indoor, general-purpose industrial environments, allowing designers to mount the control directly in the equipment cabinet and manage pressure signals without exposing the electronics to external conditions.
