Increased machine efficiency and operator safety
Whilst a solenoid interlock should provide accurate alignment of actuator and device when newly installed, during a lifetime of use actuator and device can become misaligned, causing damage to both and leading to machine downtime.
The new AZM 200 non-contact solenoid interlock from Schmersal eliminates this problem using the company's newly developed pulse echo sensor technology, which allows the actuator and interlock to engage even with an offset of +/-5mm. This simplifies mounting and reduces the need for regular maintenance and adjustment of the safety guard.
By increasing machine availability through the use of integrated electronics, the AZM 200 also reinforces Schmersal's commitment to producing safety products that not only enable conformity with regulations but also increase the efficiency of the machine or process. The new interlock is designed to increase machine uptime using innovative diagnostics to provide rapid trouble-shooting. In practice this means that a fault does not automatically lead to the machine shutting off immediately. Instead, the fault is first signalled so that machine shut down can be progressive and controlled.
Up to sixteen AZM 200 solenoid interlocks can be daisy-chained together over a distance of up to 200m, and can also be wired in series with Schmersal's CSS 180 sensor. Control Category 4 is achieved whether an installation uses one or a series of AZM 200s, which eliminates the need for additional switches and also reduces wiring and the number of control modules required.
