Dimensional Drawing of OMRON Limit Switch
Note 1. Limit Switch, The dimensional tolerance of parts not specified in the above external dimension diagrams for each model is ±0.4 mm.
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 of Limit Switch.
2. The switch contacts are compatible with both normal and micro loads, but once a load has been opened or closed, a load with a smaller capacity cannot be connected to the contacts. Otherwise,
the contact surface may become rough and the contact reliability may 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 in the head part should not be exposed to cutting chips, water, chemicals, etc. This
may cause early wear, damage, and failure of Limit Switch.
*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 AC250V 3A to two or more circuits.
*4. Please ensure this for safe use.
*5. Based on the evaluation method of EN ISO14119.
*6. This value may change depending on the switching frequency, environmental conditions, reliability level, etc. Please check with the actual load in advance.
