Technical Datasheet: Baumer FGDK 28P3001

Product Type: Through-Beam Optical Fork Sensor (Gabel-Lichtschranke)

Part Number / Part ID: FGDK 28P3001 / 10229659

Manufacturer Location: CH-8501 Frauenfeld, Switzerland

1. Product Characteristics & Application

• Sensor Type: Photoelectric Fork Sensor (Slot Sensor).

• Sensing Principle: Through-beam optoelectronic detection. The transmitter and receiver are housed directly opposite each other inside a rigid U-shaped metal frame, ensuring permanent optical alignment.

• Special Features: High structural rigidity against twisting or misalignment. Optimized for reliable edge detection, label tracking loops, sheet verification, automated material sorting channels, and parts counting on fast-moving assembly lines.

2. Electrical Data

• Operating Supply Voltage: 4.5…30 V DC (UL Class 2 Compliant)

• Electrical Design / Output Type: DC PNP

• Output Function: Normally Closed (NC) / Dark Operate (indicated by the packaging wiring map: BK = DARK / DARK OPERATE—meaning the switching output is active when the light beam is broken by a target).

• Approvals: CE, cULus Listed (IND. CONT. EQ. 1DD2)

3. Performance & Dynamic Data

• Short-Circuit Protection (SCP): Yes

• Overload & Reverse Polarity Protection: Yes

• Switching Frequency: High-speed response cycle frequency engineered for miniature part detection, label gaps, and micro-positioning synchronization feedback loops.

4. Mechanical & Environmental Data

• Housing Design: Rigid U-shaped fork/slot profile

• Housing Material: Die-cast zinc or rugged polybutylene engineering alloy

• Ambient Operating Temperature: Standard automated industrial thermal resilient profile

• Country of Origin: Made in Switzerland

5. Electrical Connection & Wiring Layout

The sensor utilizes a 3-wire termination configuration (standard cable tail or integrated connector hub mapped on the sleeve).

Core Color Assignments:

• Brown Lead (BN): +VS (4.5…30 V DC Power Supply Input)

• Black Lead (BK): DARK (Active PNP Output Signal to Load – Closed/Active when beam is blocked)

• Blue Lead (BU): 0V (Ground / Common reference line)
