Note 1. The above values are initial values of Limit Switch.
2. The switch contacts can be used for 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, oil, 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. Please contact us for other detailed conditions.
*3. Do not apply AC125V 1A to three or more circuits.
*4. Please ensure this for safe use.
*5. Based on the evaluation method of ISO 14119.
*6.This value may vary depending on switching frequency, environmental conditions, reliability level, etc. Please check with the actual load in advance.
