Schmersal Actuator | MZM 100-B1.1

Use this actuator from Schmersal to enhance the safety of guard doors in industrial environments. The component is designed to work with a solenoid switch to lock the guard doors of industrial machines when they’re running. This prevents unsafe access and protects both operator and machinery from injury and damage.

As this unit has a plastic housing that’s wear and abrasion-resistant, it can withstand heavy-duty use. It’s also quick and easy to install and can be securely fastened to the machine using tamper-proof screws.

• RoHS (Restriction of Hazardous Substances) compliant, meaning it contains only trace amounts of any harmful materials

• Compact dimensions of 24 (length) x 40 (width) x 160mm (depth) to fit small spaces

• Light weight of 337g to minimise strain on equipment

• Tightening torque of 8N for a secure lock on the device

• Process and packaging equipment

• Woodworking facilities

• Food processing equipment

This component requires very little maintenance. Regular dust removal with air blowers will ensure that the actuator works optimally for longer.

The MZM100 Safety switch from Schmersal has a solenoid interlock without a positive-linked mechanical locking mechanism. It uses an electromagnet to generate a 500-N holding force and then transmits the signal “interlock locked” to the safety-monitoring module. The forced-closed operating principle of the MZM100 switch offers multiple advantages. Mechanical wear becomes a thing of the past because of the absence of moving parts. The actuator and the locking mechanism are free from play and therefore neutralise undesired noises, even on machines with high vibrations. Despite the absence of play between actuator and interlock, the system tolerates large door misalignments. The smooth surfaces of actuator and interlock furthermore provide for the simplicity of cleaning.

An integrated sensor, functioning according to the patented pulse-echo operating principle from Schmersal, detects and monitors the position of the safety guard. Multiple safety switchgear can be monitored by means of one safety-monitoring module, without detriment to the safety level, saving money and clearing space in the control cabinet.

The MZM100 fulfils the requirements of control category 4 to EN 954-1 or SIL 3 to IEC 61508 and the magnetic locking principle complies, amongst others, with EN 60947-5-1.

Because of its compact size, the MZM100 can be fitted on conventional 40 mm machine profiles. It is suitable for light safety guards on packaging and wrapping machines thanks to its insensitivity to vibration, and is ideal for use in the food-processing industry because it has no surfaces, where dust and dirt can gather.
