Reed sensors - triac switch 230V-100W have leads with elastic cables (length of cable according to customer's requirements).
The cases of sensors are rifled (please see details on drawings).
This switch is designed to operate with neodymium ring magnet with dimensions 10x7/3,5x3 (in mm).
Nevertheless, other magnets with similar inductance value can be used.
Basic parameters are below.
