This is a coded magnetic safety switch with 1NC and 1NO contact configuration, supplied with a 10 metre cable for direct wiring into a control system. It is used in conjunction with a matching magnetic actuator to detect the position of guards or access doors on machinery, providing a signal to a safety monitoring circuit or relay. The coded design distinguishes it from standard magnetic switches by requiring a specific matched actuator, reducing the risk of defeat by substitution with a generic magnet.
