Description

The ISC Series boasts a strong metal outer shell for added durability. The swing arm offers a maximum range of motion of 95 degrees. A stainless steel idler wheel ensures smooth operation, while a punch and spring mechanism provide a secure grip. Finally, a selective M18x1.5 cable gland allows various cable sizes to be used with this unit.
The ISC-21 limit switch series is robust and versatile for various industrial applications involving resistive and low-voltage inductive loads. It offers good insulation voltage, thermal capacity, and protection against dust and water ingress.

Wiring & Display (1P)

The table describes an ISC-21 limit switch series suitable for various industrial applications involving resistive and low voltage inductive loads. It includes ratings for insulation voltage, duty rating, operational current, and temperature resistance. The switch's Ui (380V) indicates its rated insulation voltage, AC-15 (AC-15) indicates its duty rating for resistive loads, and Ie (1.5A @ Ue: 220V) specifies its operational current and voltage. The GB14048.5 standard specifies the switch's general requirements and test methods. The Ith (10A) indicates the thermal current rating. The switch's DC-13 (0.3A @ Ue: 250V) rating ensures dust and water ingress protection.
