The Omron E3FA-TP21 Photoelectric Sensor from Omron Corporation is a through-beam type device designed for precise object detection in industrial automation. It features a 20 m sensing distance, PNP open collector output, and M12 connector interface. Using a red LED (624 nm) light source, it ensures stable sensing in bright or dusty environments. Belonging to the Omron E3FA Series, this sensor offers compact cylindrical construction suitable for factory automation setups requiring high durability and consistent operation.
Widely used across automated assembly, packaging, and conveyor systems, this sensor helps ensure accurate object presence detection and stable output performance. Its rugged ABS housing and PMMA lens construction allow dependable operation even in harsh industrial conditions. The IP67 and IP69K protection ratings make it resistant to water and dust, supporting long-term reliability during high-pressure washdowns. Industries prefer it for minimizing detection errors and maintaining uninterrupted machine control efficiency.
The Omron E3FA-TP21 Photoelectric Sensor operates as a PNP output model with M12 connector configuration, ideal for compact installation and quick wiring. For users requiring an NPN output variation with the same 20 m sensing distance, the Omron E3FA-TN21 Photoelectric Sensor offers identical construction and sensing method. Those preferring a pre-wired 2 m cable option instead of a connector can select the Omron E3FA-TP11 2M Photoelectric Sensor. Alternatively, for diffuse-reflective detection without a separate receiver, the Omron E3FA-DP21 Photoelectric Sensor provides 100 mm sensing with PNP output and compact design. The Omron E3FA-TP21 ensures reliable, interference-free performance for long-distance through-beam detection tasks.
The Omron E3FA-TP21 Photoelectric Sensor reinforces Omronβs reliability in the photoelectric sensing domain, combining 20 m range, 10β30 VDC operation, and fast 0.5 ms response time. Its IP69K protection and simple alignment design support easy integration into industrial environments such as automotive lines, material handling systems, and packaging units. This model reflects the trusted performance of the Omron E3FA Series, ensuring consistent detection and minimal maintenance for industrial users across Indiaβs automation sector.
