T4N-4131 Safety Limit Switch
■ Forced open action
device(NC contacts only), it can disconnect the contact when the contact has fusing and other failures.
■ Standardized
gold-clad contacts provide high contact reliability, Can be used with both standard loads and microloads.
■ Strengthened top seal
structure improves the sealing performance.
■ Built-in contact
holder has fast-action type: 1NC/1NO; Slow-action: 1NC /1NO and 2NC.

Note1:The above values are
initial values.
Note2:Once the contact is
connected to a standard load, it can not be used to connect a smaller load. If so, the contact may result in rough surface, thus losing contact reliability.
①The protection level is
gotten based on test method of (EN60947-5-1). Please make sure its sealing under actual environmental conditions before use. The switch box has dust and oil resistance structure, but it should be
used in places without dust, oil and chemicals.
Otherwise it may lead to
premature wear, damage or malfunction.
②The durability is for
ambient temperature of 5℃ ~ 35℃ and humidity of 40% to 70% RH.
③For additional details,
please contact us.
④When the ambient
temperature is above 35℃ , more than 2 circuits 3A 250VAC loads are prohibited.
⑤The values will vary with
different switching frequency, environmental conditions, reliability level and other factors. Please confirm on the actual load in advance.
The mechanical life of
deadman lever type is more than 10,000,000 times.
