Stainless steel access interlock

Published:  05 August, 2010

SERV Trayvou Interverrouillage (STI) has launched the NXO1LTC, a new access interlock with personnel key for harsh or corrosive environments. It consists of a lock with two key slots that work on a free key / trapped key basis.

To gain access to a dangerous area, the operator has to first insert an isolation key into the lock portion. Turning this key releases the personnel key, and allows the bolt to be removed and the door opened.

The operator retains the personnel key while inside the dangerous area. This prevents the door being shut behind them and also stops the machine from being restarted by another person.

The NXO1LTC's completely stainless steel construction makes it suitable for use in harsh or corrosive environments as the paper, food, robotic, chemical and petrochemical industries.

As an entirely mechanical proposition, the NXO1LTC removes the need for cabling, reducing related maintenance costs and eliminating the risk of a cable malfunction.
STI"s safety products are heavy-duty and comply with all European machinery directives currently in force. They are popular with customers due to their strength and simple method of operation.
