Description

The Omron E3FA-TN11 utilizes a precise through-beam photoelectric sensing principle, where a separate emitter and receiver pair detect object presence by beam interruption. This method provides high reliability and immunity to target surface color or reflectivity variations. The sensor’s integrated signal conditioning delivers a clean, fast NPN switching output with a 0.5ms response time for high-speed automation applications.

Engineered for industrial durability, the sensor’s housing meets both IP67 and IP69K standards, offering protection against dust, high-pressure water jets, and steam cleaning. Its extended operating temperature range from -40°C to +85°C ensures stable performance in freezer warehouses, foundries, and outdoor installations, making it a robust solution for packaging, material handling, and safety light curtain applications.

Key Features

Long-Range Precision: 20-meter sensing distance enables reliable detection in large-scale automation setups.
Industrial-Grade Output: NPN open-collector output interfaces seamlessly with standard PLCs, relays, and microcontrollers.
Extreme Environment Rated: IP67/IP69K sealing and a -40°C to +85°C operating range guarantee performance in washdown and outdoor applications.
Fast Response Time: 0.5ms switching speed supports high-speed production line and conveyor belt monitoring.
Compact & Flexible Installation: Small 37mm x 21mm body with a fixed 2-meter cable simplifies mounting in space-constrained areas.
High-Value Build: Omron's E2E series reliability ensures long-term stability and reduced maintenance in demanding industrial cycles.
Red LED Source: 624nm visible red light beam simplifies alignment and troubleshooting during setup.
RoHS Compliant: Manufactured with environmentally safe materials, meeting global regulatory standards.

Frequently Asked Questions

What is the wiring configuration for the NPN output on the E3FA-TN11?

The NPN open-collector output has three wires: Brown (V+), Blue (V- / GND), and Black (Output). The Black output wire switches to GND (sinks current) when an object is detected. Always connect a pull-up resistor between the Black output wire and your positive supply voltage if interfacing with a microcontroller or PLC input expecting a high-level signal.

Can this sensor be used in outdoor or wet environments?

Yes, the Omron E3FA-TN11 is rated IP67 (dust-tight and protected against temporary immersion) and IP69K (protected against high-pressure, high-temperature water jets). This dual rating makes it suitable for outdoor installations, food processing washdown areas, and other harsh industrial environments where exposure to water, dust, and cleaning chemicals is common.

What is the maximum switching speed or response time?

The sensor has a fast response time of 0.5 milliseconds. This allows it to reliably detect objects on high-speed conveyor belts or in rapid indexing applications. The through-beam design inherently provides excellent immunity to background light and target surface variations, ensuring consistent high-speed operation.

Does the 2-meter cable have a standard connector, or is it hard-wired?

The sensor comes with a fixed, integrated 2-meter cable without a standard quick-disconnect connector. The cable is terminated with bare wires (Brown, Blue, Black) for direct connection to your control system terminal blocks or a mating cable harness. This design enhances environmental sealing compared to connectorized versions.
