The Autonics BEN Series offers compact, amplifier-built-in photoelectric sensors with universal voltage capabilities, designed for versatile industrial applications. These sensors are characterized by their ease of installation, featuring integrated LED indicators for quick status checks and an adjustment VR (Variable Resistor) for setting operation modes (Light ON or Dark ON). Both status and output are clearly indicated by LEDs. A key feature is the built-in IC photodiode, which enhances performance by providing resistance to ambient light and electrical noise, ensuring reliable operation in various environments.

Function Description

The BEN Series encompasses several sensing types:

• Through-beam (BEN10M-TFR/TDT): Consists of separate emitter and receiver units. Detection occurs when an object interrupts the beam between the two units. Ideal for long-distance detection and precise object positioning.
• Retroreflective (BEN5M-MFR/MDT, BEN3M-PFR/PDT): Combines the emitter and receiver in a single unit, using a reflector (MS-2 or MS-4) to return the emitted light. An object is detected when it breaks the beam between the sensor and the reflector. The BEN3M-PFR/PDT models include a built-in polarizing filter, which is particularly effective for detecting shiny or reflective objects by preventing false detections from direct reflections.
• Diffuse Reflective (BEN300-DFR/DDT): Also combines the emitter and receiver in a single unit. Detection occurs when the light emitted from the sensor reflects off the target object and returns to the receiver. Suitable for detecting objects at close range without the need for a separate reflector.

The sensors offer flexible output options:

• Relay Contact Output (BEN-TFR/MFR/PFR/DFR): Provides a robust relay output suitable for controlling various loads, including AC and DC circuits. This type is powered by universal AC/DC voltage.
• Solid State Output (BEN-TDT/MDT/PDT/DDT): Features NPN/PNP open collector simultaneous output, ideal for direct interfacing with PLCs and other control systems. This type operates on DC voltage.

Usage Features

• Easy Installation: The compact design and built-in amplifier simplify mounting and wiring. LED indicators on the product provide immediate feedback on operation and stability, reducing setup time.
• Operation Mode Selection: A VR adjustment allows users to easily switch between Light ON (output turns ON when light is received) and Dark ON (output turns ON when light is interrupted) modes, adapting to various application requirements.
• Sensitivity Adjustment: A dedicated VR is provided for sensitivity tuning, especially crucial for diffuse reflective types to optimize detection based on target characteristics and mounting conditions.
• Reflector Options: For retroreflective models, MS-2 reflectors are standard, with MS-4 available for tighter mounting spaces.
• Ambient Light/Noise Immunity: The built-in IC photodiode provides enhanced resistance to external light interference and electrical noise, ensuring stable detection in challenging industrial environments.
• Polarizing Filter (BEN3M-PFR/PDT): This feature is critical for applications involving highly reflective surfaces, preventing false detections by filtering out direct reflections from the target. The light from the emitter is horizontally polarized, reflects off the MS-2 reflector, becoming vertically polarized, and is then detected by the receiver.
• Output Protection: DC models include reverse polarity protection and short-circuit protection, safeguarding the sensor and connected equipment from electrical faults.

Mounting and Sensitivity Adjustment Guidelines:

• Through-beam Type:
  1. Mount emitter and receiver facing each other.
  2. Adjust the receiver's position to the center of the stability range (indicated by the LED).
  3. Verify stable operation by introducing the target at the optical axis.
  4. Note: Translucent objects or objects smaller than Ø16mm may cause light penetration and missed detections.
• Retroreflective Type:
  1. Mount the sensor and reflector (MS-2) face-to-face.
  2. Adjust the sensor's position until the indicator turns ON, optimizing detection by adjusting the reflector or sensor.
  3. Secure both units after confirming target detection.
  4. For multiple sensors, maintain a minimum spacing of 30cm to prevent interference.
  5. For highly reflective targets, position the target at a 30° to 45° angle relative to the sensor or use a polarizing filter model (BEN3M-PFR/PDT) to prevent false detections.
• Diffuse Reflective Type:
  1. Place the target at the desired detection point.
  2. Turn the adjustment VR from minimum until the operation indicator turns ON (position 'a').
  3. Remove the target and turn the VR until the indicator turns ON again (position 'b'). If it doesn't turn ON, 'b' is at the maximum VR position.
  4. Set the VR to the center of 'a' and 'b' for optimal sensitivity.
  5. Sensing distance is specified for 100x100mm non-glossy white paper and may vary based on target size, surface, and gloss.
