The sensor operates on a 5-24V DC supply, delivers an NPN output with a maximum load current of 100 mA, and is set to Light-On switching mode. The switching frequency is rated at 3 kHz, supporting high-speed detection in automation sequences. ## Selection Considerations vs. Peer Models Compared to the Omron E3Z-T61K 2M, the EE-SX872A offers a significantly shorter sensing distance (5 mm vs. 15 m) and a lower IP rating (IP64 vs. IP67), but provides a faster response (0.17 msec vs. 1 msec). The E3T-FT11 has a longer sensing range of 500 mm and IP67 but uses red LED light and has a slower response of 1 msec, while the EE-SX872A uses infrared light. Neither peer shares the T-slot body style of the EE-SX872A; they are rectangular, requiring different mounting provisions. ## Mechanical and Electrical Integration The sensor has a compact T-slot body measuring 12 mm × 12 mm × 31 mm, constructed from PBT, and is rated IP64 for dust and splash-water resistance. Electrical connection is via a prewired 2 m cable with bare wire ends; the NPN output is compatible with most PLC digital inputs and sinks up to 100 mA. An integral indicator confirms power-on and switching state, aiding commissioning and troubleshooting. ## Regulatory Documentation The EE-SX872A carries CE and RU compliance marks, as indicated in the standard documentation, satisfying the certification requirements for European and Russian markets.","metaTitle":"Omron EE-SX872A Through-Beam Sensor, 5 mm, NPN, IP64","metaDescription":"Omron EE-SX872A compact T-slot through-beam photoelectric sensor, 5-24V DC, NPN output, 0.17 ms response, IP64.
