In-Depth Technical Specifications

Optical Performance Characteristics

Featuring a 3.18mm (0.125") sensing gap, the OPB841W55Z provides exceptional resolution for detecting small components. The through-beam infrared sensing technology ensures high noise immunity with typical forward current of 20mA (50mA max) and collector current capacity of 30mA. The phototransistor output delivers fast response times, typically in the microsecond range, making it ideal for high-speed applications.

Robust Electrical Parameters

• 30V collector-emitter breakdown voltage for enhanced circuit protection
• Operating temperature range: -40 C to +80 C (industrial grade)
• Dark current: <1 A (typical) for minimal power consumption
• Current transfer ratio: 10% minimum at 20mA forward current

Mechanical Design Features

The chassis-mount module comes in a pre-wired package with 6" (152mm) lead wires for easy installation. The housing provides IP40 environmental protection and features precise optical alignment with 0.5mm mechanical tolerance. The slot width accommodates standard 0.8mm thick actuator flags.
