Schmersal Actuator for Use with Solenoid Interlock Safety Switch รหัส AZM 161-B6-2177

The EX-AZM161 is a solenoid interlock switch designed for explosives atmospheres. It will ensure that sliding, hinged and removable guarding devices cannot be opened until hazardous conditions have come to an end (when used in combination with the control elements of a machine, e.g. fail-safe standstill monitors or fail-safe delay timers). They are also used for cases in which the opening of a guarding device represents a non-permissible intrusion in a production process.
The switching element with interlock on the EX-AZM161 is not physically connected to the actuator but functionally brought together or separated on switching. When the guard device is opened in the uninterlocked condition, the actuator is separated from the base unit. In the process, NC contacts are positively opened and NO contacts closed.
Interlocking is carried out by means of a latching bolt which blocks the actuator so that it cannot be withdrawn from the interlock. The machine control circuit is only enabled when the actuator has been fed into the interlock and the latching bolt is in the blocking position. This is ensured by contact monitoring of the latching bolt.

ATEX.

Use this actuator from Schmersal to prevent access to moving parts of machines when they're running. This component works together with a solenoid interlock safety switch and is designed for use on hinged safety guard doors. To enhance workplace safety, it latches onto the switch when the machine is running, so you can't open it until the machine stops or is in manual mode.
This unit is made of a high-quality steel material that's robust and corrosion-resistant, so it can withstand use in heavy-duty industrial environments. It's useful in production and manufacturing assembly lines, especially those with machines running at high speeds.

• Meets Restriction of Hazardous Substances (RoHS) standards, meaning it contains only limited amounts of any harmful materials
• ATEX (ATmosphères EXplosibles) approved for use in hazardous environments

• Process control
• Packaging equipment
• Hazardous work areas

To mount this actuator, it's important to ensure that the centre of rotation is on the same plane as the upper edge of the safety switch. You should also use screws with countersunk heads to ensure they're flush with the surface of the actuator.
