The Model NSR51 Heavy duty industrial limit switches are sensing limits on machines and industrial equipments. The heavy duty rugged design makes them suitable for most industrial applications.The body structure is covered with iron with static paint. Shaft mechanisms are made of stainless steel. NSR51 Belt Misalignment Switches, It can be mounted on both sides of the machine to be attached to the chassis. It is designed to prevent damage to the machine. System decreases downtime and maintenance costs and time can be saved.The micro switch used in the products is approved by VDE. All products are produced as accordance with CE standards. Also It meets EAC standards for the Russian market. NSR51 series products do not require any maintenance. Because it is a limit switch that requires high reliability, it is a full-scale limit switch for heavy industry with improved environmental resistance and high mechanical strength.

Features
| Resistant to heavy conditions. | |
| The enclosure uses aluminum alloy die cast | |
| Mounting flanges are resistant to intense force. | |
| Resistant to high temperatures and instantaneous temperature changes | |
| The actuator part has a large total travel (TT), so it can be used as a switch | |
| High mechanical strength can be fully utilized | |
| Excellent environmental resistance | |
| Protective structure: The oil seal on the shaft and the O-ring seal on the cover provide an exterior immersion,
oil and dust resistant structure. |
|
| It has high durability against high vibration and shock performance | |
| It is mechanically long-lasting with roller bearings. |
