NSR51-LS Series

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. Becauseit is a limitswitch that requires high reliability, it is a full-scale limit switch for heavy industry with improved environmental resistance and high mechanical strength.

Resistant to heavy conditions
The enclosure uses aluminum alloy casting.
Mounting flanges are resistant to intense force.
Resistant to high temperature and instant temperature changes.
The actuator part has a large total travel (TT), so it can be used as a switch. It has high mechanical strength.It has a high level of environmental resistance.
Protective structure: The oil seal on the shaft and the O-ring seal on the cover provide a structure resistant to water immersion, oil and dust.
It has high durability against high vibration and shock performance.
It is long-lasting with its roller bearings.
