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.
