| e2a cylindrical proximity sensor 1 cylindrical proximity sensor e2a safe mounting with greater sensing distance ? ensures a sensing distance approximately 1.5 to 2 times larger than that of any conventional omron sensor. ? problems such as the collision of workpieces are eliminated. ? full range of standard si zes (m8, m12, m18 and m30; both long and short barrels) ? modular construction simplifies customization. 2 e2a cylindrical proximity sensor note: m30 non-shielded models with double sensing distance and short barrels cannot be mounted due to the necessary separation distan ce from the surrounding metal. standard sensing models are t hus available. m12 shielded 4.0 mm pre-wired brass 34 (50) pnp e2a-m12ks04-wp-b1 2m e2a-m12ks04-wp-b2 2m npn e2a-m12ks04-wp-c1 2m e2a-m12ks04-wp-c2 2m 56 (72) pnp e2a-m12ls04-wp-b1 2m e2a-m12ls04-wp-b2 2m npn e2a-m12ls04-wp-c1 2m e2a-m12ls04-wp-c2 2m m12 connector brass 34 (48) pnp e2a-m12ks04-m1-b1 e2a-m12ks04-m1-b2 npn e2a-m12ks04-m1-c1 e2a-m12ks04-m1-c2 56 (70) pnp e2a-m12ls04-m1-b1 e2a-m12ls04-m1-b2 npn e2a-m12ls04-m1-c1 e2a-m12ls04-m1-c2 non-shielded 8.0 mm pre-wired brass 34 (50) pnp e2a-m12kn08-wp-b1 2m e2a-m12kn08-wp-b2 2m npn e2a-m12kn08-wp-c1 2m e2a-m12kn08-wp-c2 2m 56 (72) pnp e2a-m12ln08-wp-b1 2m e2a-m12ln08-wp-b2 2m npn e2a-m12ln08-wp-c1 2m e2a-m12ln08-wp-c2 2m m12 connector brass 34 (48) pnp e2a-m12kn08-m1-b1 e2a-m12kn08-m1-b2 npn e2a-m12kn08-m1-c1 e2a-m12kn08-m1-c2 56 (70) pnp e2a-m12ln08-m1-b1 e2a-m12ln08-m1-b2 npn e2a-m12ln08-m1-c1 e2a-m12ln08-m1-c2 m18 shielded 8.0 mm pre-wired brass 39 (59) pnp e2a-m18ks08-wp-b1 2m e2a-m18ks08-wp-b2 2m npn e2a-m18ks08-wp-c1 2m e2a-m18ks08-wp-c2 2m 61 (81) pnp e2a-m18ls08-wp-b1 2m e2a-m18ls08-wp-b2 2m npn e2a-m18ls08-wp-c1 2m e2a-m18ls08-wp-c2 2m m12 connector brass 39 (53) pnp e2a-m18ks08-m1-b1 e2a-m18ks08-m1-b2 npn e2a-m18ks08-m1-c1 e2a-m18ks08-m1-c2 61 (75) pnp e2a-m18ls08-m1-b1 e2a-m18ls08-m1-b2 npn e2a-m18ls08-m1-c1 e2a-m18ls08-m1-c2 non-shielded 16.0 mm pre-wired brass 39 (59) pnp e2a-m18kn16-wp-b1 2m e2a-m18kn16-wp-b2 2m npn e2a-m18kn16-wp-c1 2m e2a-m18kn16-wp-c2 2m 61 (81) pnp e2a-m18ln16-wp-b1 2m e2a-m18ln16-wp-b2 2m npn e2a-m18ln16-wp-c1 2m e2a-m18ln16-wp-c2 2m m12 connector brass 39 (53) pnp e2a-m18kn16-m1-b1 e2a-m18kn16-m1-b2 npn e2a-m18kn16-m1-c1 e2a-m18kn16-m1-c2 61 (75) pnp e2a-m18ln16-m1-b1 e2a-m18ln16-m1-b2 npn e2a-m18ln16-m1-c1 e2a-m18ln16-m1-c2 m30 shielded 15.0 mm pre-wired brass 44 (64) pnp e2a-m30ks15-wp-b1 2m e2a-m30ks15-wp-b2 2m npn e2a-m30ks15-wp-c1 2m e2a-m30ks15-wp-c2 2m 66 (86) pnp e2a-m30ls15-wp-b1 2m e2a-m30ls15-wp-b2 2m npn e2a-m30ls15-wp-c1 2m e2a-m30ls15-wp-c2 2m m12 connector brass 44 (58) pnp e2a-m30ks15-m1-b1 e2a-m30ks15-m1-b2 npn e2a-m30ks15-m1-c1 e2a-m30ks15-m1-c2 66 (80) pnp e2a-m30ls15-m1-b1 e2a-m30ls15-m1-b2 npn e2a-m30ls15-m1-c1 e2a-m30ls15-m1-c2 non-shielded 20.0 mm pre-wired brass 44 (64) (see note.) pnp e2a-m30kn20-wp-b1 2m e2a-m30kn20-wp-b2 2m npn e2a-m30kn20-wp-c1 2m e2a-m30kn20-wp-c2 2m 30.0 mm 66 (86) pnp E2A-M30LN30-wp-b1 2m E2A-M30LN30-wp-b2 2m npn E2A-M30LN30-wp-c1 2m E2A-M30LN30-wp-c2 2m 20.0 mm m12 connector brass 44 (58) (see note.) pnp e2a-m30kn20-m1-b1 e2a-m30kn20-m1-b2 npn e2a-m30kn20-m1-c1 e2a-m30kn20-m1-c2 30.0 mm 66 (80) pnp E2A-M30LN30-m1-b1 E2A-M30LN30-m1-b2 npn E2A-M30LN30-m1-c1 E2A-M30LN30-m1-c2 size sensing distance connection body material thread length (overall length) output configuration operation mode no operation mode nc e2a cylindrical proximity sensor 3 model number legend example: e2a-m12ls04-m1-b1 standard, m12, long barrel, shielded, sn=4 mm, m12 connector, pnp-no e2a-m08kn04-wp-b1 5m standard, m8, short barrel, non-shielded, sn=4 mm, pre-wired pvc cable, pnp-no, cable length=5 m 1. basic name e2a 2. sensing technology blank: standard double distance 3. housing shape and material m: cylindrical, metric threaded, brass s: cylindrical, metric threaded, stainless steel 4. housing size 08: 8 mm 12: 12 mm 18: 18 mm 30: 30 mm 5. barrel length k: standard length l: long body 6. shield s: shielded n: non-shielded 7. sensing distance numeral: sensing distance: e.g. 02=2 mm, 16=16 mm 8. kind of connection wp: pre-wired, pvc m1: m12 connector (4-pole) m3: m8 connector (4-pole) m5: m8 connector (3-pole) 9. power source and output b: dc, 3-wire, pnp open collector c: dc, 3-wire, npn open collector d: dc, 2-wire e: dc, 3-wire, npn voltage output f: dc, 3-wire, pnp voltage output 10.operation mode 1: normally open (no) 2: normally closed (nc) 11.specials (e.g., cable material, oscillating frequency) 12.cable length blank: connector type numeral: cable type 2 3 4 5 6 7 8 9 10 11 1 12 e2a@-@@@@@-@-@@-@@ 4 e2a cylindrical proximity sensor specifications dc 3-wire models note 1. the response frequency is an average value. measurement conditions are as follows: stan dard target, a distance of twice the sta ndard target distance between targets, and a se tting distance of half the sensing distance. 2. when using any model at an ambient temperature between ?

(unit: mm) note 1. in the case of using the supplied nuts. if true flash mounting is necessary, apply a free zone of 1.5 mm. 2. in the case of using the supplied nuts. if true flush mounting is necessary, apply a free zone of 4 mm. power off the proximity sensor may output a pulse signal when it is turned off. therefore, it is recommended that the load be turned off before turning off the proximity sensor. power supply transformer when using a dc power supply, make sure that the dc power sup- ply has an insulated transformer. do not use a dc power supply with an auto-transformer. mutual interference when installing two or more sensor s face-to-face or side-by-side, ensure that the minimum distances given in the following table are maintained.

wire the cable through an independent metal conduit to pre- vent against proximity sens or damage or malfunctioning. cable extension standard cable length is less than 200 m. the tractive force is 50 n. mounting the proximity sensor must not be subjected to excessive shock with a hammer when it is installed, otherwise the proximity sensor may be damaged or lose its water-resistivity. do not tighten the nut with excessive force. a washer must be used with the nut. maintenance and inspection periodically perform the following checks to ensure stable operation of the proximity sensor over a long period of time. 1. check for mounting position, disloc ation, looseness, or distortion of the proximity sensor and sensing objects. 2. check for loose wiring and connections, improper contacts, and line breakage. 3. check for attachment or accumulation of metal powder or dust. 4. check for abnormal temperature conditions and other environ- mental conditions. 5. check for proper lighting of indicato rs (for models with a set indi- cator.) never disassemble or repair the sensor. environment water resistivity do not use the proximity sensor underwater, outdoors, or in the rain. operating environment be sure to use the proximity sensor within its operating ambient temperature range and do not use the proximity sensor outdoors so that its reliability and life expectancy can be maintained. although the proximity sensor is water resistive, a cover to protect the prox- imity sensor from water or water-soluble machining oil is recom- mended so that its reliability and li fe expectancy can be maintained. do not use the proximity sensor in an environment with chemical gas (e.g., strong alkaline or acid gasses including nitric, chromic, and concentrated sulfuric acid gases). inrush current a load that has a large inrush current (e.g., a lamp or motor) will damage the proximity sensor, in which case connect the load to the proximity sensor through a relay. type
