Product_description: ['Omron E2EC proximity sensor has a 2 mm inductive sensing with 3-wire, PNP output and NO contactThe E2E inductive proximity sensors are extremely small in diameter with 3 mm, 4 mm, 6.5 mm, M4 and M5 versions available. The stable long sensing distance of these sensors enables high performance for detection of ferrous metal even when the work flow is unsteady. The E2E series of proximity sensors have 4 indicator lamps on them in a 360 deg layout making it extremely easy to check the operation status.Ultra small size, but surprisingly easy installationHigh-speed response frequency stably detects moving objects: 5 kHz maxFour indicator lamps for easier indicator positioningSpecial mounting brackets reduce time and efforts for installationProtective stainless steel spiral tube against wire breakage is available (M4, M5 only)Standard sensing object - 6.5 x 6.5 x 1 mm ironYellow operation indicator.
