Front/Side Mount Photoelectric Sensors BH Series

Product Overview

The BH Series photoelectric sensors offer versatile installation options, allowing users to choose between front mounting using an M18 nut and fastening cap or side mounting with M3 bolts and nuts. This flexibility ensures easy integration into various industrial environments. The sensors are designed to produce either individual or simultaneous NPN and PNP open collector outputs through simple wiring configurations. With an IP67 protection structure, these sensors guarantee reliable and error-free operation, even in challenging environments with moisture or dust.

Key Features

• Versatile Installation: The sensors can be installed either through front mounting with an M18 nut and fastening cap or side mounting using M3 bolts and nuts, providing flexibility in application.
• Simultaneous NPN/PNP Output: Designed to support both NPN and PNP open collector outputs, these sensors can be configured for individual or simultaneous output, depending on the wiring setup.
• Extended Sensing Distance:
  • Through-beam type: Capable of detecting objects at distances up to 20 meters.
  • Polarized retroreflective type: Effective at distances up to 4 meters.
  • Diffuse reflective type: Offers a sensing distance of up to 1 meter or 300 millimeters.
• Compact Design: The BH Series sensors are designed with compact dimensions of W 14 mm × H 34.5 mm × L 28 mm, making them suitable for installation in space-constrained environments.
• Mirror Surface Rejection (M.S.R.): This function prevents false detections from reflective objects such as metals or mirrors, particularly useful in the polarized retroreflective type.
• Built-In Sensitivity Adjustment: Each sensor is equipped with a built-in adjuster for easy sensitivity control, allowing fine-tuning according to specific application needs.
• Selectable Operation Modes: Users can switch between Light ON and Dark ON modes based on the application requirements.
• Visual Indicators: The sensors include:
  • Operation Indicator: A red light that indicates sensor operation.
  • Stability Indicator: A green light that provides feedback on the stability of the sensing operation.
  • Power Indicator: Available on specific models, providing a clear indication of power status.
• Advanced Protection Circuits: The sensors are built with reverse power protection and output short overcurrent protection circuits to safeguard the device and ensure reliable operation.
• Interference Prevention: Mutual interference prevention functions are integrated, except in the through-beam type, ensuring accurate detection even in environments with multiple sensors.
• Durable Construction: With an IP67 protection rating, the BH Series sensors are designed to withstand harsh conditions, including exposure to water and dust, ensuring long-lasting performance.
