Before procurement teams confirm E3JM-R4M4T-US, they typically review Omron SMPS 24V 10A, E3Z D61 2M and Omron Sensors to double-check performance ratings, stock availability, and supplier credibility carefully.
Omron E3JM-R4M4T-US Photoelectric Sensor
The Omron E3JM-R4M4T-US Photoelectric Sensor delivers retroreflective with MSR function detection up to 4 m using an E39-R1 reflector and red LED (660 nm) for precise object sensing. It operates on 12 to 240 VDC or 24 to 240 VAC and includes a relay output with terminal block connection. This model is part of the Omron automation range under the Omron Photoelectric Sensors category and the Omron E3JM Series. Built with Light-ON/Dark-ON switch selection, SPDT control output (250 VAC, 3A max.), 30 ms response time, and IP66 protection, it features a conduit socket (1/2-14NPT) and is UL-listed for industrial reliability.

Omron E3JM-R4M4T-US features a sensing distance of up to 4 meters when paired with the E39-R1 reflector, providing consistent detection of opaque objects with a minimum diameter of 75 mm. Operating on a wide voltage range of 12 to 240 VDC and 24 to 240 VAC, this sensor supports SPDT relay outputs with Light-ON/Dark-ON modes that can be easily selected to match specific system requirements.
With a fast response time of just 30 milliseconds and an adjustable timer function ranging from 0.1 to 5 seconds, the E3JM-R4M4T-US enhances control and flexibility in automated processes. It delivers stable performance even under harsh conditions, thanks to its robust construction using ABS, polycarbonate, and methacrylic resin, and its ability to withstand vibrations (up to 1.5 mm double amplitude) and shocks (up to 500 m/sΒ²). The sensor maintains optimal functionality across a wide temperature range of β25Β°C to 55Β°C and holds an IP66 protection rating for dust and water resistance.
Trusted by engineers and automation professionals worldwide, Omron E3JM-R4M4T-US is a reliable, easy-to-integrate sensor that meets the demands of modern industrial systems.
