Product Description
Schmersal BNS 303-11Z-2211 5,0M – Magnetic safety sensor of the BNS 303 series. It detects without contact whether the guard is closed: when the matching magnetic actuator approaches, the contacts in the sensor switch. Evaluation is via a suitable safety monitoring module. The manufacturer's article number is 101146586, the EAN 4030661139647.
Scope of delivery
Actuator must be ordered separately.
Important note
The contact configuration for versions with or without LED is identical., Contact symbols shown for the closed condition of the guard device.
