Allen Bradley Guardmaster Interlock Switch, 2NO/2NC

Provide enhanced security and stability for your machine guard safety process and protect personnel with the Prosafe RKSE Series Rotary Key Switch box by Allen Bradley Guardmaster.

This trapped key unit isolates power to machinery when the coded key is removed, ensuring that personnel cannot access dangerous areas where machinery may be in motion. This unit is perfectly designed for safety applications which require a pre-defined sequence of operations to access machinery. This type of reliable mechanical interlocking device is usually used in environments where electrical interlock systems may be unsuitable or expensive to install and maintain, such as areas with explosive atmospheres.

To remove the key it must be rotated 90° anti-clockwise. This alters the state of the positively guided switch contacts. The contacts can be reverted to their original state by re-inserting the key and rotating it 90° clockwise, which will trap it again.

• New range of rotary switch interlocking systems: the new keys are compatible with the old barrels, although they have an additional notch (old keys will not fit the new barrels)
• Secure trapped key interlocking system allows access to machinery only after power has been switched off
• Key locked, switch ON; key released, switch OFF
• Surface-mounted housing
• IP65 rated – total protection against dust ingress and durable against low pressure water jets
• Robust stainless-steel housing for exceptional durability

Key must be ordered separately.
