High-resolution Digital Proximity Sensor with Separate Amplifier E2C-EDA Series pe ct otice. A Digital Proximity Sensor At Last! Finally a Digital Proximity Sensor Capable of High-resolution Sensing with Unprecedented Ease Sensors An Impressive Lineup of Sensor Heads to Handle a Wide Variety of Applications Industry First An Array of Heads Flexible Cables Provided as a Standard Feature The lineup includes some Sensor Heads as thin as 3-mm in diameter and others that are thin and flat. Narrow installation spaces are not a problem for these models. Still other Sensor Heads are heat resistant or rated IP67 for superior environmental resistance. These models are capable of high-resolution sensing even in harsh environments. With flexible cables connecting the Preamplifier to the Amplifier, installation on moving parts is never a problem. The twin-output models can also output an open-circuit alarm. In that rare instance where the cable breaks, the E2C-EDA can then send out an alarm that greatly simplifies the task of locating the faulty Sensor. Flexible cable Connector Flat Heat resistant 3 dia. to 200°C 5.4 dia. 8 dia. M10 M18 May be cut any length up to 3 m (models ending in -F) High-resolution Sensing Unaffected by Environmental Swings Excellent temperature characteristics at 0.08%/°C (5.4-mm dia.

E2C-ED01(-@) 0.55 Sensing distance (mm) In addition to repeat accuracy of 1-µm or better, the temperature characteristics of the E2C-EDA are flat. This means that environmental factors, such as temperature swings in the morning and at night, will not affect high-resolution positioning and screening. 0.50 0.45 −20 0 20 40 60 Ambient Sensor Head temperature (˚C) 2 Industry Leader High-resolution Digital Proximity Sensor with Separate Amplifier E2C-EDA Series Amplifiers Simple and Reliable Measurements with Micron-level Resolution ustry First Industry First Two Clear, Large, and Easy-to-Read Digital Displays Digital Display Simplifies Installation and Settings The E2C-EDA features two large, easy-to-read digital displays. Since the digitized detected and threshold values can be checked at the same time, settings are simple and reliable for just about anyone. Various teaching methods are also available for settings that cannot be made consistently by different operators. In the stable sensing zone, the E2C-EDA generally reads 1,500 or higher (see note 2). This way you can tell at a glance whether the current installation and settings are within the optimal range. Detected value Threshold value Character size: 6 mm Note 2: This reading is only a guideline because there may be some variation between Sensors. Also refer to the Engineering Data because values may vary with non-standard objects. Threshold Teaching MODE Key (See note 1.) UP/DOWN Keys for fine threshold value adjustments Note 1: Press the MODE Key with the E3C-EDA running to switch to individual teaching modes, Fine Positioning, or Zero Reset. Connector for Connecting Sensor Heads to Amplifiers A Shielded Connector is used for more reliable wiring and easier cable handling. Since the press-fit connector allows repeat connections, wiring and head replacement are simple and reliable. Leader Support for High-resolution Positioning and Screening Patent pending Fine Positioning Maximizes Digital Changes Fine Positioning maximizes changes in the digital value as you get closer to the sensing point. More precise sensing can be achieved by executing Fine Positioning with the workpiece positioned at the point to be maximized. Sensing Distance - Digital Value Characteristic (Typical) Display reads 1,500 when Fine Positioning is executed. 5.4-mm dia.

Height inspection Capacitor sleeve mounting inspection Area Output (Twin-output Type) An OK/NG result is easily obtained because the E2C-EDA outputs a signal between two threshold values. Digital value Threshold 1 3000 3000 2000 Non-defective product Threshold 2 2000 Output between threshold 1 and threshold 2. Height inspection Screw assembly inspection Mutual Interference Prevention The E2C-EDA has a mutual interference prevention function that uses intermittent sensing via optical communications to enable up to 5 Sensors to be combined very closely together. This feature enables multiple measurements to be made in a machine or process. Optical communications Five Sensors max. 4 High-resolution Digital Proximity Sensor with Separate Amplifier E2C-EDA Series Positioning Teaching Press-fit inspection (positioning) Position teaching yields consistent settings that cannot be matched by operator settings. Conventional dial type Digital type Perfect Operator setting inconsistencies Settings are simple enough for anyone with teaching (reduces operator setting inconsistencies). Gap inspection Zero Reset (Fixed Threshold) Metal chip and shaving buildup inspection for presses When using a fixed sensing gap (threshold), the origin and reference position can be corrected quite simply if needed, such as when changing the process being performed. Change in Machine Arrangement The origin (reference) is offset. Zero Reset Correction completed! Simple and Common Sensor Operation in Devices Platform Concept Ensures Common Operation and Programming Devices The basic functions and Programming Devices like the Mobile Console are the same for the E2C-EDA as they are for the E3X-DA-S Digital Fiber Sensor and the E3C-LDA Laser-type Photoelectric Sensor. Just select the right type of E2C-EDA for the application, and the rest is easy. E3C-LDA Laser-type Photoelectric Sensors E3X-MDA Digital Fiber Sensor (2-Amplifier Type) E3X-DA-S Digital Fiber Sensor E2C-EDA Digital Proximity Sensor OMRON's unique wiring-saving Connector reduces the amount of wiring required even with a mixture of different sensing types. 5 Ordering Information ■ Sensors Sensor Heads Type Appearance Sensing distance 3 dia. × 18 mm Shielded Cylindrical 5.4 dia. × 18 mm 0.6 mm 1 mm 8 dia. × 22 mm Repeat accuracy E2C-EDR6-F (See note 2.) 1 µm E2C-ED01-@ (See notes 1, 2, and 3.) 2 µm E2C-ED02-@ (See notes 1, 2, and 3.) 2 µm E2C-EM02-@ (See notes 1, 2, and 3.) 2 µm E2C-EV05-@ (See notes 1, 2, and 3.) 5 µm E2C-EM07M-@ (See notes 1, 2, and 3.) 2 µm E2C-EM02H (See note 2.) 2 mm M10 × 22 mm Model 1 µm Screw 2 mm 30 × 14 × 4.8 mm Flat 5 mm M18 × 46.3 mm Unshielded Screw 7 mm M12 × 22 mm Heat-resistant Screw 2 mm Note 1.
