Safety switch is easy to integrate
A novel noncontact safety switch uses the latest pulse-echo technology to determine door position and lock status.
Machine safety specialist Schmersal has introduced a new noncontact safety switch that uses the latest pulse-echo technology to determine door position and lock status Compared with conventional mechanical safety switches, the new AZ 200 offers offset tolerances of +/-5mm, which can dramatically increase productivity by reducing downtime of a machine should an actuator be improperly or incorrectly aligned

Safety interlock switch can never be bypassed
Schmersal (UK) have introduced a new range of safety interlock switches that are activated by an individually-coded, geometrically-unique, actuating key with 15,000 different combinations.
Light barriers take on space limitations
Schmersal (UK) Ltd, specialists in man-machine safety systems, have introduced the SLC400 range of optoelectronic safety light grid barriers and curtains, designed to guard plant and machinery
When a safety guard is open, the actuator of the AZ 200 is completely inserted in its plastic enclosure to reduce the risk of injury to operators.
Further advantages include its ergonomic operation and design that allows for effortless integration and easy fitting to standard profiles used in machine construction.
To save money, if several safety guards need to be monitored, multiple AZ 200s can be wired in series and their signals evaluated through a single safety relay.
This daisychaining principle is also suitable when different safety systems - all based on the same technology - need to be combined in one application.
The user can, for instance, connect a combination of series-wired safety switches, solenoid interlocks and safety sensors to a single safety relay.
Control Category 4 is achieved whether an installation uses one or a series of AZ 200s, which eliminates the need for additional switches and also reduces wiring and the number of control modules required.
The new unit was also specifically designed and certified to IEC61508 and BS EN62061 and is suitable for applications up to SIL 3.
Commenting for Schmersal, Product Manager Dan Walters says: "We believe the AZ 200 will be ideal for machine builders as it offers similar benefits to our AZM 200 solenoid interlock, which is proving extremely popular".
