Technical Datasheet: BALLUFF BES054N

Ordering Code: BES054N

Part Number / Model: BES M08MI-PSC30B-S49G

Product Category: Inductive Proximity Sensor

1. Product Characteristics & Application

• Sensor Type: Inductive Proximity Sensor

• Housing Design: Threaded mini cylindrical barrel type (M8 × 1) with a rugged metal housing (MI designator line).

• Sensing Range (Sn): 3 mm (Extended sensing distance optimized for an M8 housing size).

• Mounting: Non-flush mountable (indicated by the extended 3 mm range for the compact M8 body profile).

• Special Features: Engineered for robust small-scale automation. It provides precise non-contact metal target verification, making it an excellent match for space-restricted industrial assemblies, miniature component tracking lines, and high-density conveyor networks.

3. Performance & Dynamic Data

• Ambient Operating Temperature (Ta): -25 °C ≤ Ta ≤ 70 °C

• Short-Circuit Protection (SCP): Yes

• Overload & Reverse Polarity Protection: Yes

• Switching Frequency: High-cyclic conversion velocity designed for rapid target loops and precise mechanical position feedback.

4. Mechanical & Environmental Data

• Dimensions: M8 × 1 mm standard metric threads / Full-metal robust cylinder structure

• Housing Material: High-grade nickel-plated brass or specialized wear-resistant alloy face

• Country of Origin: China (As indicated on label: Country of origin: China)

• Item Code / Batch: 253247 / 2445CN / 09420519

5. Electrical Connection & Wiring Layout
