Non-Contact Safety Switches HS3A Interlock Switches XW Series E-Stops Overview HS3A Non-contact RFID Safety Switches Key features: * RFID non-contact interlock switch, Category 4 and PLe (EN/ISO 13849-1) compliant. * The sensor head with built-in safety function (redundant solid state output with internal monitoring) eliminates the need for a designated safety module. * RFID ensures detection of slow-moving, open, sliding, and rattling doors. * Multicode and unicode sensor heads are available. Unicode sensor head (one sensor head corresponds to one actuator) prevents tampering with the use of an unassigned spare actuator. * Sensor head can be installed in 5 directions. * Degree of protection IP67. Actuator IP67, IP69K (Note) Note: IP69K is a degree of protection specified by Deutsches Institut fur Normung (DIN), DW 40050 Part 9 for hot and high-pressure water.

When any of the HS3A switches detects that the safety guard is open, or when a failure has occurred on any of the switches, the system tuns off the machine. However, the external control system cannot detect which safety guard is open or where a failure has occurred.

When the off-center displacement of the interlock switch (sensor head) and actuator is 0 mm. 2. When surface-mounted on aluminum. When using by embedding in metal, pay attention to the operation distance affected by the metal. In non-metallic environment, the typical turn-on distance increases to 30mm. When connecting a single switch (max.) Light Curtains Min. Response Time Distance Table 2: Response Time Note: To ensure safety, both safety outputs (OA and OB) must always be evaluated. Singlechannel use of the safety outputs as shown below leads to a reduction of safety category stipulated in EN954-1. 800-262-IDEC (4332) * USA & Canada 379
