It detects ferrous targets at 2.5 mm non-flush and switches at up to 1 kHz, carrying a 50 mA load over 10–30 VDC. The 9 mm cube housing is rated IP67, suitable for washdown areas or dusty environments. Current consumption is 13 mA; the 1 m cable terminates the connection. ## NC vs. NO – how the output type affects your choice The exact same form factor, sensing distance, and electrical ratings appear on the NO sibling E2SQ211MOMS. The only difference is the output state: this part opens its load circuit when a target is present (break contact), while the NO version closes the circuit on target. Physical fit in a 9 mm panel cutout, cable length, and mounting are identical, so a board swap is possible – but the logic inversion means you must verify whether the downstream input expects a normally open or normally closed signal. For a safety or fault-annunciation circuit where a loss of sensor signal (wire break) must be detected, the NC configuration is the standard fail-safe choice.","metaTitle":"Omron E2SQ261MOMS Inductive Sensor, NC, 2.5mm, 9mm, IP67","metaDescription":"Active production E2S series NC inductive sensor. 2.5 mm sensing, 10-30 VDC, 50 mA load, 1 kHz switching, IP67. 9 mm cube, 1 m cable.

However, the output logic is inverted. If the controller expects a normally open signal (closes on target), this NC sensor will open on target, which may trigger an alarm or stop the process unless the input logic is reprogrammed or rewired.
