Brooks Instrument Model Optical Sensor Alarm

About this part

Brooks Instrument Model 7940 is a legacy optical sensor alarm. Surviving configured-unit records show multiple suffix-coded versions, so electrical supply and interface details must be taken from the complete nameplate identifier rather than inferred from the 7940 base model

Configurations vary. Verify the exact unit before choosing a replacement.
