New Original Omron E3JK-DR11-C Photoelectric Switch Sensor
1. Product Overview
The E3JK-DR11-C is a brand-new cuboid diffuse-reflective photoelectric sensor from Omron’s E3JK universal AC/DC free power series. It adopts an integrated built-in power supply circuit design, supporting wide-range AC and DC dual power input without separate power adapters. This model features relay contact output, 2.5-meter maximum diffuse sensing distance, red LED light source, and a 2-meter fixed PVC cable connection.
As a cost-effective general industrial photoelectric sensor, it is widely used for object presence detection, counting, position confirmation and material shortage monitoring on packaging machines, conveyor lines, food processing equipment, printing machinery and automated assembly stations. Every genuine original unit undergoes strict factory aging testing, EMC anti-interference inspection and IP64 dustproof/waterproof sealing verification to maintain stable operation in environments with workshop dust, water splashes and electromagnetic noise generated by motors and inverters. It is equipped with an adjustable sensitivity potentiometer and dual-status LED indicators for easy on-site calibration and fault judgment, and the matched metal mounting bracket simplifies fixed installation on equipment frames.
2. Main Functions
2.1 Diffuse-Reflective Object Detection
- Single-body diffuse reflection design, no separate reflector or transmitter-receiver pairing required
- Max 2.5 m effective sensing distance detected with standard 300×300 mm white test paper
- Adjustable detection threshold via built-in trimmer potentiometer, compatible with targets of different colors, sizes and reflectivity
- Automatically identifies opaque objects including cartons, plastic parts, metal sheets, paper and wood materials
- Supports switchable Light-ON and Dark-ON operation modes to match different control logic demands
2.2 Universal AC/DC Power & Relay Output Control
- Wide-range free power input: AC 24–240 V / DC 12–240 V, compatible with almost all factory power distribution systems
- Built-in mechanical relay single-contact output (1C contact), capable of directly driving small solenoid valves, signal lamps and auxiliary relays
- Complete internal circuit protection against overvoltage, surge current and reverse voltage damage
- Dual LED indicators: orange operation light for trigger status, green stability light for reliable sensing zone prompt
2.3 Industrial Environmental Adaptability
