Product description

The Siemens 3SE6605-2BA01 is a magnetically operated switch contact block with a large rectangular housing (25 x 88 mm). It offers 1 NO (normally open) and 1 NC (normally closed) contact elements and features an M8 plug connection. The pin assignment is specified as Pin1=21, Pin2=22, Pin3=13, Pin4=14. This switch requires either the 3SE6704-2BA solenoid or the 3SE6701-2BA (for increased operating distance), which must be purchased separately.

This switch is designed for robust safety monitoring in industrial environments, providing both signaling and interlocking functions. The M8 plug ensures a secure and quick connection.
