It operates on 12–24 VDC and provides an open collector (NPN) output rated at 100 mA max load current. The emitter draws 15 mA, receiver 20 mA, for a total 35 mA current consumption. ## Output polarity — check your input card The E3Z-LT61 uses an NPN open collector output that sinks current to common. If your panel uses PNP-sourcing sensors like the E3Z-LL81, rewiring of input common and load connections is required. Load power supply voltage maxes at 26.4 VDC, and load current at 100 mA — enough for a direct PLC input but not for driving a relay coil without an interposing interface. ## Sensing distance and light source Through-beam at 60 m means the emitter and receiver are separate housings; the beam must be aligned and unobstructed. The red LD (655 nm) produces a visible spot approximately 5 mm diameter at 3 m, which helps with rough alignment using a white card or reflective tape. JIS/IEC Class 1 and FDA Class 2 laser rating means no laser safety signage is required in most industrial environments, though standard light-curtain precautions apply.","metaTitle":"Omron E3Z-LT61 Photoelectric Sensor, Through-beam 60m, Red L","metaDescription":"Omron E3Z-LT61 through-beam photoelectric sensor with 60 m range, red laser diode 655 nm, NPN open collector output, 12–24 VDC.
