The new SR unit from Fortress Interlocks is a compact safety key switch that is said to be ideal for isolating power to machinery.
For example, when the key is trapped inside the SR unit the power to machinery is on, and when the key is free, power is off. This allows the person carrying the freed key to enter the machinery or guarded area safely and power is not resumed until the key is returned. Other sequences can also be specified.
The key switch is heavy duty, housed in a metal enclosure which is IP rated 65/66/67. Its compact design allows the customer plenty of space for wiring.
