It operates using a transmitter-receiver (through-beam) sensing method, which provides high detection reliability and resistance to background interference. The unit incorporates an internal amplifier and relay output, allowing direct switching of loads without additional interface modules. With an IP65-rated ABS housing and 2-meter pre-wired cable, it is suitable for machinery, conveyors, and automated production lines operating in demanding conditions. Key Features: Through-Beam Detection: Separate transmitter and receiver configuration for stable 5 m sensing range. Long Sensing Distance: Reliable object detection up to 5 meters. SPDT Relay Output: Supports switching loads up to 3 A for direct control applications. Wide Supply Voltage Range: Operates on 12–240 VDC or 24–240 VAC. DARK-ON Operation Mode: Output activates when the light beam is interrupted. Built-In Amplifier: Eliminates need for external amplification modules. IP65 Protection: Resistant to dust and water spray in industrial environments. 2 m Pre-Wired Cable: Simplifies installation and wiring. The E3JK-5M2 delivers the reliability and precision required for long-distance object detection in industrial automation systems.
