Sensors & Switches – Allen-Bradley

Sensors & Switches are essential industrial automation components from Allen-Bradley that detect, monitor, and control mechanical, electrical, and environmental conditions in automated systems. These devices include proximity sensors, photoelectric sensors, limit switches, safety switches, and other sensing technologies designed to provide accurate input to PLCs, PACs, motor starters, and industrial control systems.

What Are Sensors & Switches?

Sensors & Switches detect changes in position, motion, temperature, pressure, or other physical conditions and convert them into electrical signals for control systems. Allen-Bradley sensors and switches provide reliable, real-time feedback, enabling automated decision-making, machine protection, and safety compliance in industrial environments.

Allen-Bradley Sensor & Switch Product Families

• Proximity Sensors – Inductive, capacitive, and magnetic sensors for detecting metal or non-metal objects without physical contact.
• Photoelectric Sensors – Sensors that use light to detect objects, distance, or changes in surface conditions.
• Limit Switches – Mechanical switches that activate when a moving part reaches a predetermined position.
• Safety Switches – Devices designed to detect access or hazardous conditions and ensure machine shutdown or safe operation.
• Pressure & Flow Sensors – Monitors for pneumatic and hydraulic systems that provide input to control systems for process automation.
