Technical Datasheet: BALLUFF Through-Beam Sensor Pair

Ordering Code (Complete Pair): BOS00CW

Model/Type (Receiver): BLE 18KW-PA-1PP-S4-C

Model/Type (Emitter): BLS 18KW-XX-1P-S4-L

1. Product Overview & Key Features

The BOS00CW is a high-performance through-beam photoelectric sensor system comprising a dedicated emitter (transmitter) and a matching receiver unit.

• Housing Design: Threaded barrel right-angle type (M18 × 1), featuring a $90^\circ$ optical angle head for mounting in tight mechanical gaps.

• Operating Principle: Through-beam (Emitter beams a steady light path directly to the receiver; interruption triggers an immediate state switch).

• Alignment/Adjustment: The receiver housing is equipped with an integrated multi-turn potentiometer on the back face to accurately dial in distance sensitivity.

2. Electrical Data

• Operating Voltage: 10…30 V DC (Supply Class 2 compliant)

• Rated Insulation Voltage (Ui): 75 V DC

• Electrical Design: DC PNP

• Output Function: Normally Open (NO) & Normally Closed (NC) complementary output staging.

3. Outputs & Performance

• Permanent Current Rating: 100 mA max.

• Short-Circuit Protection (SCP): Yes

• Overload & Reverse Polarity Protection: Yes

• Status Indicators: Transparent rear ring windows housing visible LEDs (Green for stability/power, Yellow for output switching state).

4. Mechanical & Environmental Data

• Dimensions: M18 × 1 mm thread / Right-angle optical head profile

• Housing Material: Rugged industrial polymer / ABS blend

• Ambient Operating Temperature: -25 °C…55 °C

• Ingress Protection (IP Rating): IP67

• Country of Origin: Made in Italy

• Included Accessories: M18 plastic mounting locking nuts and washers.

5. Electrical Connection & Wiring Layout

Both the emitter and receiver units feature an integrated M12 × 1 circular male connector (4-pin configuration).
