BS4 series
The BS4 series miniature photoelectric sensors are available in seven different shapes (K, L, R, T, TA, F, Y types) with built-in connectors, providing maximum flexibility for various user applications and installation settings. The sensors are designed to minimize false triggering caused by foreign objects. They offer high visibility, and the action indicator light can be viewed from multiple directions.
Main Features
• Compact size with built-in connector
• Supports dedicated connector cables (sold separately) and universal connector cables
• Flexible selection of various shapes (K, L, R, T, TA, F, Y types)
• Horizontal detection surface and body to minimize detection errors
• Action indicator light visible from multiple directions
• Models available with light-on or dark-on indicator lights
• High impact and vibration resistance
• High-speed response frequency: 2kHz
• Standard and flexible connector cables (sold separately)

Compact Size with Built-in Connector
The built-in connector miniature photoelectric sensors can be installed in limited spaces and can be used with dedicated or universal connector cables.

Multiple Shapes Available for Installation Flexibility
Seven different shapes are available for installation in various applications.

Models Available with Light-on and Dark-on Indicators
Models are available with light-on or dark-on indicators based on user needs or applications.

Light-on indicator (BS4-□2M-□)

Dark-on indicator (BS4-□2R-□)
Flexible Connector Cables (sold separately)
Flexible connector cables can be used in dynamic applications where moving or bending parts are required without damaging the cables.

Multi-Directional Action Indicator Light
The action indicator light can be viewed from multiple directions, allowing users to see the action status in various environmental settings.

High Impact and Vibration Resistance
The sensors provide vibration resistance up to 2,000Hz and impact resistance up to 1,500G, making them suitable for installation in harsh environments.

Application Cases

◆ Palletizer
The miniature photoelectric sensor with flexible cable is used to check the correct position of the gripper while stacking the cathodes, anodes, and separators of batteries without damaging the cable.

◆ PCB Transport Line
The miniature photoelectric sensor is used to detect the position of transport pallets on the PCB loader.

◆ Laser Marking on Semiconductor Components
The miniature photoelectric sensor and stepper motor are used to move and check the X-Y axis position of the pallet during the laser marking process on semiconductor components.

◆ Milling Machine
The miniature photoelectric sensor and stepper motor are used to control the X-Y axis in a compact milling machine.
