Compact Design for Precise Industrial Sensing

The Pepperl+Fuchs UB250-F77-E2-V31 is a high-precision ultrasonic proximity sensor designed for non-contact object detection across a 20–250 mm sensing range, with an adjustable 45–250 mm working range via its teach-in function—activated by a 3-second low-level pulse. Housed in a miniature rectangular casing (23 x 12 x 31 mm, 10 g), it seamlessly integrates into space-constrained industrial environments, such as robotic grippers or compact machinery. The M8 x 1 connector ensures quick, standardized wiring, while the IP67 rating protects against dust and temporary water immersion. A yellow LED indicator provides clear feedback on switching status and teach-in activation, simplifying setup and real-time monitoring. Its lightweight polycarbonate housing and any-position mounting flexibility make it ideal for applications requiring precision in tight layouts.

Reliable Performance with Advanced Ultrasonic Technology

Engineered for consistent operation, this sensor utilizes a 400 kHz ultrasonic transducer to detect objects regardless of material, color, or texture, offering superior versatility in complex industrial setups. It operates on a 20–30 V DC power supply (12–20 V DC with reduced sensitivity) with a PNP normally open (NO) output, delivering 200 mA load current with short-circuit and overload protection. Key features include a ±1 mm repeat accuracy, 2.5 mm hysteresis to minimize signal fluctuations, and a 10 Hz switching frequency, ensuring stable performance in high-vibration environments. The sensor’s 300 m maximum cable length supports remote installations, while temperature compensation (0.17%/K) maintains detection precision across its -25°C to 70°C operating range, making it reliable for both cold storage and moderate-temperature applications.

Durability and Compliance for Demanding Environments

The UB250-F77-E2-V31 meets international standards (EN/IEC 60947-5-2:2020) and carries UL certification (Class 2 power source), ensuring global compatibility in automation systems. Its robust construction—with a polycarbonate housing and epoxy/hollow glass sphere transducer—resists chemical exposure, mechanical shocks (30 g, 11 ms), and vibrations (10–55 Hz), making it suitable for harsh industrial settings. The factory-set 250 mm switching point can be customized via the teach-in function, streamlining integration into applications like conveyor belt monitoring, automated material handling, or robotic part positioning. Backed by Pepperl+Fuchs’ industrial expertise, this sensor offers long-term durability with minimal maintenance, embodying excellence in compact ultrasonic sensing solutions for critical automation tasks.
