Omron EE-SX674A Photomicrosensor
The Omron EE-SX674A Photomicrosensor is a close-mounting slot sensor that detects machine components as they enter its fixed 5 mm through-beam sensing path. The emitter and receiver are incorporated into the sensor structure, allowing the optical relationship to remain fixed while a target moving through the slot creates the detection event. This arrangement supports compact presence and position detection where installation space or surrounding machine geometry limits sensor placement. An infrared LED provides the sensing light, while the NPN output communicates the resulting state to compatible control circuitry. Light-ON or Dark-ON operation is selectable, and the unit operates from 5 to 24 VDC using a 4-pole connector. For close-mounting detection, the EE Series offers the EE-SX674A within the compact slot sensor range used for machine detection with Omron control products.

Omron is a globally recognized automation leader, known for manufacturing innovative sensing solutions that combine compact design, advanced optical technology, and industrial-grade durability. The EE-SX674A is part of Omron’s renowned EE-SX series, purpose-built for engineers who require fast, accurate sensing in space-limited systems. Designed with a 5 mm slot width and NPN output, this photoelectric slot sensor is ideal for tasks such as object positioning, indexing, and actuator arm detection in conveyor lines or assembly machines.
This slot type sensor uses an infrared LED (940 nm) for stable throughbeam sensing, featuring selectable Dark-ON / Light-ON modes and only 12 mA max current draw. It operates on 5–24 VDC, is protected against short circuits, and connects via a 4-pole plug-in connector. With an IP50-rated polybutylene phthalate (PBT) housing, the slot sensor Omron is built to withstand vibration (20–2,000 Hz) and shock (500 m/s²), delivering stable output even in tough industrial settings.
Common applications include slot photoelectric sensor mounting in PCB handling units, label feed detection, textile threading paths, and compact packaging machines. Maintenance teams favor this Omron slot sensor for its durability and plug-and-play compatibility, while engineers value its precision under fast-moving conditions. With years of proven reliability across industries, the EE-SX674A provides consistent detection performance within compact setups.
