Technical Datasheet: BALLUFF BES01M6

Ordering Code: BES01M6

Part Number / Model: BES 516-383-S49-C

Product Category: Inductive Proximity Sensor

1. Product Characteristics & Application

• Sensor Type: Inductive Proximity Sensor

• Housing Design: Threaded mini cylindrical barrel type (M8 × 1).

• Sensing Range (sn): 2.5 mm (Extended sensing range for an M8 housing size).

• Mounting: Non-flush mountable (indicated by the extended non-flush range for M8 size and target mechanical specifications).

• Special Installation Note: As highlighted prominently on the label (Attention: Lock washers must be used! / Achtung: Zahnscheiben unbedingt verwenden!), the included serrated lock washers must be fitted during installation to maintain tight thread locking under mechanical vibration.

• Tightening Torque: Maximum tightening mechanical limit is 8 Nm.

2. Electrical Data

• Operating Voltage: 10…30 V DC (Supply for use in the secondary of a Class 2 source of supply)

• Rated Current Consumption: ≤ 200 mA

• Housing Material: High-grade robust metal construction

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

• Item Code / Batch: 231499 / 1603CN

• Included Accessories: Mounting locknuts and required mechanical tooth lock washers (visible inside the bottom pouch compartment).

5. Electrical Connection & Wiring Layout

The sensor features an integrated standard compact 3-pin circular male connector interface (S49 interface designator).

Pinout Assignment:

• Pin 1: Brown wire → + (10…30 V DC Power Supply)

• Pin 4: Black wire → Output Switching Signal (Load)

• Pin 3: Blue wire → – (0 V Ground / Common)
