Castell Solenoid Controlled Switch

The KSS is a heavy-duty solenoid controlled key driven electrical switch interlock ideal for the controlled isolation or switching of low current. This product is used where a process can send a signal to release a key, e.g. a robot has to finish a cycle prior to isolation. Upon removal of the key, the KSS switch contacts change to isolate the process. This type of isolator should be used for short term, off load isolation. The unit is ready for mounting into an existing panel or for surface mounting within its own IP65 rated lockable steel enclosure. The KSS is manufactured from either brass or stainless steel making it suitable for use in standard or harsh corrosive environments.

A typical application of KSS solenoid controlled switch is machine guarding. It is usually used in combination with an access interlock such as the Salus for part body access or an access interlock with an exchange key for full body access control.

The KSS breaks the machine safety circuit, ensuring a machine is shut down. Once the machine has completed the cycle, an external signal is received by the solenoid, which is indicated by an illuminated LED. Activating the green button on the KSS will enable the key to be turned and removed ensuring the power is locked out. The key can then be taken to the AIE access interlock to enable access to the machine.

The machine cannot be restarted until the door is closed, the bolt is trapped in the AIE access interlock and the key is removed and taken to the KSS solenoid controlled switch.
