OMRON

OMRON

The standard for safety limit switches. A full lineup is offered globally.
[Features]
● Contact configurations include 1NC/1NO, 2NC, 2NC/1NO, and 3NC. (MBB specifications are available for slow action).
● Also available are M12 connector types that reduce labor and make replacement easier.
●Compatible with both general loads and microloads.
● Au-clad contacts with high contact reliability are used as standard.
● Complies with the safety contact requirements of EN115-1, EN81-20, and EN81-50 (slow action types only).
● UL, EN (TÜV), and CCC standards obtained.

massApproximately 92g (for D4N-1A20R)

Note 1. The above values ​​are initial values of Limit Switch.
   2. Once a load has been switched, a load with a smaller capacity cannot be connected to the contact. 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 sealing performance under the actual usage environment and conditions should be confirmed in advance.
      The switch box body is protected from the intrusion of dust, oil, water, etc., but the operation key insertion port in the head part should not be exposed to cutting chips, oil, water, chemicals,etc., when using the switch. This
      may cause early wear, damage, and failure of Limit Switch.
*2. The durability conditions are at 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. This value may change depending on the switching frequency, environmental conditions, reliability level, etc. Please check with the actual load in advance.
