Company Overview

Founded in 1903 and now operating under Rockwell Automation, Allen Bradley has a long history in industrial control solutions. The brand is known for delivering reliable, integrated hardware that supports factory automation, material handling, and process safety, with full compliance to international standards.

Sensor Technologies

Allen Bradley provides a broad array of sensor types for industrial applications:

  • Proximity Sensors: Non-contact sensors ideal for detecting metal parts in conveyors and machinery systems.
  • Photoelectric Sensors: Models such as RightSight and VisiSight excel in object detection, counting, and jam prevention.
  • Inductive Sensors: Designed to operate reliably in harsh industrial environments with resistance to debris and moisture.

Limit Switch Solutions

The company's mechanical and safety limit switch offerings include rugged units for critical industrial applications:

  • General-purpose limit switches: Such as the 801 series, used for end-of-travel detection.
  • Compact precision models: Including the 802B and 802T series with NEMA 6/IP67 or oiltight construction for tough environments.
  • Safety limit switches: The 440P family meets ISO 13849 and EN 62061 for machine guarding applications.

Speed Monitoring Devices

Speed sensing is critical for conveyor safety, and Allen Bradley delivers reliable solutions:

  • Bulletin 808 Speed Sensing Switches: Detect under-speed, over-speed, zero-speed, and reverse rotation, supporting plugging and anti-plugging control in conveyor systems.
  • These switches support shaft speeds up to 2000 rpm, multiple mounting options, and include safety lockout features.

Safety Control Integration

Complementing its sensor lineup, Allen Bradley provides safety controllers and relays:

  • MSR series relays: Used for speed monitoring and fail-safe system shutdowns.
  • Guard locking interlocks: Bulletin 440T series ensures safe access control.
  • These components integrate with PLC platforms like ControlLogix, CompactLogix, and GuardLogix for centralized monitoring and control.

Certifications and Applications

Allen Bradley products are certified to UL, CSA, CE, and UKCA standards. They are widely used in industries such as automotive, food and beverage, packaging, and logistics, especially in material handling and processing environments.

Conclusion

With its extensive product range—including sensors, limit switches, speed sensing devices, and safety relays—Allen Bradley continues to set standards in industrial automation. The brand’s commitment to integration, safety compliance, and performance makes it a preferred partner for OEMs, system integrators, and engineers worldwide.
