Oil-Resistant/Oil-Proof Photoelectric Sensors BJR Series

Product Overview

The BJR series oil-resistant/oil-proof photoelectric sensors are specifically designed for use in environments rich with cutting oil and lubricants, making them ideal for applications in the automotive and machine tool industries. These sensors offer long-distance detection capabilities, reaching up to 15 meters with the through-beam type. Key features such as the Mirror Surface Rejection (MSR) function and mutual interference prevention ensure stable and error-free operation. The sensors are easy to install, featuring metallic nuts for the screw mounting holes, which accommodate M3 bolts, and they maintain excellent performance even when exposed to various oils.

Features

• Long Sensing Distance:
  • Capable of detecting up to 15 meters (through-beam type), 3 meters (polarized retroreflective), and 1 meter (diffuse reflective) with high-performance lenses.
• Mirror Surface Rejection (MSR):
  • Available in the polarized retroreflective type to reduce errors caused by shiny surfaces.
• Compact Size:
  • Dimensions of 11 mm (width) × 32 mm (height) × 20 mm (length) allow for easy integration into tight spaces.
• Adjustable Operation Modes:
  • Switchable between Light ON and Dark ON modes with built-in sensitivity adjuster for precise detection settings.
• Protection Features:
  • Equipped with reverse power protection and output short overcurrent protection circuits.
• Interference Prevention:
  • Mutual interference prevention available in reflective types to minimize cross-talk between sensors.
• Noise Immunity:
  • High resistance to electrical noise and minimal impact from ambient light, ensuring reliable operation.
• Durability and Environmental Resistance:
  • Optimized for environments with cutting fluid or lubricating oil, meeting IP67 protection standards (IEC) and IP67G oil resistance standards (JEM).

Installation and Maintenance

The BJR series sensors are designed for easy installation and maintenance. The screw mounting holes are reinforced with metallic nuts, facilitating installation with M3 bolts. This feature also allows for straightforward maintenance and ensures durability even in environments exposed to various oils.

Additional Features

• Power Supply:
  • Operates with a 10-30 VDC power supply, with protection against voltage fluctuations.
• Current Consumption:
  • Through-beam type: Emitter and receiver each consume ≤ 20 mA. Reflective types consume ≤ 30 mA.
• Control Output:
  • Options for NPN or PNP open collector outputs to suit various system requirements.
• Durability:
  • Withstands vibration (1.5 mm double amplitude) and shock (500 m/s²), ensuring performance in harsh conditions.
• Environmental Conditions:
  • Operating temperature range from -25 to 60 °C, and storage temperature from -40 to 70 °C.
