Allen-Bradley 836T-T252JX24X15 Pressure Switch

Allen-Bradley 836T-T252JX24X15 Pressure Switch is an electro-mechanical pressure control device from Rockwell Automation’s Bulletin 836T family, designed for industrial pressure monitoring and control in machine-tool and general hydraulic or pneumatic systems. It uses a copper-bellows sensing element to translate pressure changes into a mechanical switch action, enabling a defined on/off response without requiring electronic sensing. The unit is configured for industrial service with a robust enclosure and a typical 1/4" NPT female process connection, making it suitable for mounting in common fluid-power and control loops. In applications such as starting or stopping equipment, signaling control circuits, or clamping operations in machine tools and similar environments, this 836T switch provides a reliable, mechanical threshold response essential for straightforward, rugged operation in demanding manufacturing settings.
