New Original OMRON E3JK-DR11-C 2m Diffuse Reflective Photoelectric Sensor
Product Overview
E3JK-DR11-C is an original heavy-duty built-in power supply photoelectric sensor developed by OMRON, belonging to the classic E3JK universal industrial sensor series. This is a diffuse-reflective type optical sensor equipped with red LED light source, designed for object presence detection, counting, position triggering and conveying positioning in automated production lines. It supports wide-range AC/DC universal power input, adopts SPDT relay contact output, and provides switchable Light-ON / Dark-ON working modes. With adjustable detection sensitivity and IP64 dustproof & splash-proof housing, it can stably work in dusty, slightly oily workshop environments. The sensor transmits switching signals to PLC input modules to realize automatic logic control. It complies with CE, RoHS international industrial standards and is widely applied in packaging machinery, conveyor systems, printing equipment, food processing assembly lines and general factory automation detection occasions.

Primary Main Functions
- Non-contact Object Detection: Detects workpieces, cartons, packaging boxes and conveyed goods without physical contact, realizing object arrival & absence judgment.
- Dual Working Mode Switching: Freely toggle between Light-ON (output ON when receiving reflected light) and Dark-ON (output ON when light is blocked) to match diverse control logic demands.
- Continuous Sensitivity Regulation: Rotary potentiometer fine-tunes detection distance to avoid false triggering caused by different object colors or surface reflectivity differences.
- Relay Contact Signal Output: Mechanical contact output is compatible with all brands of PLC digital input terminals, applicable to both AC and DC control circuits.
- Anti-interference Environmental Adaptation: Effectively resists ambient light interference, dust and water splashing, suitable for harsh production workshop conditions.
- Equipment Counting & Position Triggering: Cooperates with PLC to complete product counting, positioning stop, conveyor start/stop and limit protection actions.
- Wide Voltage Compatibility: Universal AC/DC power input eliminates power supply limitation, convenient for on-site electrical cabinet wiring transformation.
- Long Service Life Stable Operation: Long mechanical & electrical relay lifespan ensures 24-hour uninterrupted long-term running for automation equipment.
Key Technical Features
- Universal wide-range AC/DC power supply design greatly simplifies on-site wiring, no need to configure dedicated DC power adapters separately.
- Visible red light spot makes optical axis alignment and installation calibration intuitive and fast, greatly shortening equipment debugging time.
- Robust IP64 sealed casing prevents dust accumulation and coolant splashing inside the sensor, reducing failure rate in oily workshops.
- Mechanical relay output features strong load capacity, which can directly drive small solenoid valves and indicator lamps without intermediate relays.
- Optimized optical lens structure effectively suppresses background reflection interference, avoiding misdetection caused by ground or wall reflection.
- Large adjustable potentiometer and mode toggle switch facilitate easy operation even with gloves worn during on-site maintenance.
- Standard rectangular overall structure matches universal mounting brackets, flexible for various installation angles and positions on machinery frames.
- Mature circuit design with strict aging testing guarantees consistent detection performance throughout long-term service cycle.
