FAQ – Meaning of Suffixes for Connection Method in E2E NEXT

Q: What do the suffixes related to “connection method” mean in the Omron E2E NEXT proximity sensors, as shown in the Model Number Legend? 

A: These suffixes define the physical connection type of the sensor: whether it is pre-wired, uses an M12 or M8 connector, follows the old or IEC pin arrangement, includes a Smartclick feature, or has a robot (bending-resistant) cable. The following table explains each abbreviation: 

• (blank) → Pre-wired models (standard fixed cable)

• M1 → M12 connector models (old pin arrangement)

• M3 → M8 (4-pin) connector models (old pin arrangement) 

• M5 → M8 (3-pin) connector models (old pin arrangement)

• M1G → M12 connector models (IEC pin arrangement)

• M1J → M12 pre-wired standard connector models (old pin arrangement)

• M1GJ → M12 pre-wired standard connector models (IEC pin arrangement)

• M1TJ → M12 pre-wired Smartclick connector models (old pin arrangement)

• M1TGJ → M12 pre-wired Smartclick connector models (IEC pin arrangement)

• M1TGJR → M12 pre-wired Smartclick connector models with robot (bending-resistant) cable (IEC pin arrangement)

• M3G → M8 (4-pin) connector models (IEC pin arrangement)

Additional notes

• Old vs. IEC pin arrangement:
  For the DC 2-wire configuration (Normally Open), when the model has the “G” suffix the connection is between pins 1 and 4, and without the “G” suffix the connection is between pins 3 and 4. 
  
  
  
  For the DC 2-wire configuration (Normally Closed), with the “G” suffix the connection is between pins 1 and 2, and without the “G” suffix the connection is between pins 2 and 3. 
  
  
  For 3-wire models, the distinction between New Arrangement and Old Arrangement does not apply; it only applies to DC 2-wire models.

• Smartclick connectors:
  Suffixes with TJ indicate Smartclick versions, which allow quick locking without torque adjustment

• Robot cables:
  The R suffix (e.g., M1TGJR) means the model uses a bending-resistant robot cable for continuous flexing applications.

• Polarity:
  Some models include a T suffix to indicate no polarity, simplifying wiring and reducing the chance of misconnection.

• Cable lengths:
  Pre-wired models usually have 2 m cables, with options such as 5 m. Pre-wired connector models often use ~0.3 m cables leading to a connector.

• Environmental resistance:
  E2E NEXT sensors with oil-resistant PVC or Smartclick connectors improve durability in harsh environments with cutting oils.
