Machine Guard Systems - Access Interlocks

Supplier: Newfema

Access interlocks - Single and dual key versions

Price Guide: POA

Access interlocks are manufactured in 316L stainless steel to provide rugged, industrial grade method of interlocking guard doors. They are actuated by either a lever or a rod which is connected to a chain.

One advantage of the access interlocks is that there is no need to run power wires to the gate. Power is disconnected by a trapped key on a control panel or by a Prosafe RKS type unit and the key is then handcarried to the gate by the operator.

Single key access/chain interlock is used to interlock hatches, guards and doors where full body access is not required. Dual key access/chain interlock is similar to the single key version but has a secondary key to allow ‘2 key in’ or ‘key exchange’ conditions.

The key exchange version may be used where whole body access is required, as the secondary key can be used as a personnel key. Actuator locking arm is tolerant to misalignment ± 10mm.

The lever arm retracts fully into the block protecting it from damage when the guard is open. The chain option is designed to lock badly fitting guards doors or gates or to connect to moveable equipment & parts.
