Dimensional Drawing of OMRON Limit Switch
Limit Switch Main unit
Note 1. In the above external dimensions of each model, the dimensional tolerance of unspecified parts is ±0.4mm. ( ) dimensions are reference values.
2. There is variation in the simultaneity of the ON/OFF action of contacts with 2 or more poles (2NC, 2NC/1NO. 3NC), so please check before use.

Note 1. The above values are initial values.
2. The switch contacts are compatible with both normal and micro loads. However, once a load has been opened or closed, a load with a smaller capacity cannot be connected to the contacts. This may cause
the contact surface to become rough and the contact reliability to be impaired.
*1. This protective structure is based on a test method based on the standard (EN60947-5-1), and the sealability under the actual usage environment and conditions should be confirmed in advance.
The switch box body is protected from the intrusion of dust and water, but the operation key insertion port on the head should not be exposed to cutting chips, water, chemicals, etc.
This may cause early wear, damage, and failure.
*2. The durability conditions are for an ambient temperature of 5 to 35°C and an ambient humidity of 40 to 70% RH.
*3. Do not apply 125V AC 1A to two or more circuits.
*4. Please ensure this for safe use.
*5. Reference value for micro loads.
This value may change depending on the switching frequency, environmental conditions, reliability level, etc. Please check with the actual load in advance.
