The PS31L-NS11R2-M00 is a robust limit switch designed for presence/absence detection, positioning, and travel limit applications in industrial environments. It is constructed with a durable zinc alloy (Zamack) body and head, providing high mechanical resistance and an IP66 degree of protection against dust and water. This model is equipped with an adjustable lever with a stainless steel roller, a 1/2" NPT cable inlet, and a Zb type snap-action contact block with a 1NO+1NC configuration. Electrically, it is rated for a conventional thermal current (Ith) of 10A and a rated insulation voltage (Ui) of 500V. Its precise operating points, positive opening operation, and immunity to electromagnetic disturbances make it a reliable choice for industrial control and automation systems.
