• Features
Ergonomic design for reduced hand, wrist and arm stresses associated with repeated switch operation; requires no physical pressure to operate
Designed to minimize the possibility of defeat and accidental actuation
Two diverse-redundant microcontroller-based photoelectric STB self checking touch buttons
Continuous internal self-checking operation, Immunity to ambient light, EMI and RFI interference
High excess gain to cut through heavy contamination, LED power, output and fault indicators
Designed to be interfaced with Duo-touch SG two-hand control modules or other control systems that comply, at minimum, with ANSI NFPA 79 or IEC 60204-1 two-hand control requirements
Immune to ambient EMI and RFI interference
Protected against reverse polarity and transient voltages
Protected against false pulse on power-up, overload and short-circuit protection
Electronics fully epoxy-encapsulated fiber reinforced polyester base
Polyamide red button with metal base E-stop button
Robust 13 ga (0.090 in) cold rolled steel with powder coat paint run bar housing
Polypropylene copolymer STB mount
