ncGard Range




Non-contact safety switches are interlocking devices that are designed to protect people, industry and productivity.

Non-contact safety switches are ideal for use in applications where precise guidance of guards is difficult.  Due to the design they are extremely long-lasting devices that require minimal maintenance.  In addition they are resistant to shock and vibrations and offer a high level of prevention against tampering.
