Tapeswitch-HE-seriesTapeswitch Corp.'s newly released Multi-gate monitoring system consists of the HE Series non-contact safety interlock switches and multi-gate SCU-1 control unit for machine guarding, where monitoring for a guard is required and locking is not required, such as in packaging, paper, food and beverage, dairy, pharmaceutical and aluminum machinery applications.  HE Series Interlock switches — the latest coded magnetic non-contact switches — feature fully encapsulated solid state, single point switching with built-in, dual-color, LED status indication. The switches offer a CAT 4, SIL 3 PLe safety performance level. The system has 2 N/O and 1 N/C bi-directional solid state outputs, which offer simple series connection with a 7mm switching distance. When combined with the SCU-1 control unit, the HE series is a multi-gate switch solution capable of monitoring up to 30 switches in the series. Since the HE series is a HED double switch, it reduces the amount of wiring for multiple gates and reduces the brackets needed for mounting the switches.
