Panasonic SF4C-H16-J05 Safety Light Curtain

Technical Overview

Ultra-slim 13mm Type 4 PLe SIL3 safety light curtain featuring 16 channels, 20mm beam pitch, 320mm protective height, 7ms response time, and IP67 resin body.

Key Features

Ultra-slim 13 mm body reduces machine footprint and expands operational opening width.
Combines PNP and NPN polarities in a single model with an LED polarity indicator.
Integrated fixed and floating blanking functions to accommodate fixed obstacles or material feedthrough.
Equipped with the ELCA (Extraneous Light Check & Avoid) function to suppress mutual interference.
Highly visible large multi-purpose LED indicators on both sides for operation and error feedback.
Laser-welded IP67 and IP65 protection structure for resistance to demanding environments.

Industrial Applications

1. Compact Robotic Assembly Cells

Deploying physical safety barriers near automated pick-and-place robots. The SF4C-H16-J05's ultra-slim 13 mm profile and 7 ms response time allow close-proximity integration to maximize safety while conserving shop floor area.

Problem Solved

Eliminates bulky metal guards and decreases the minimum safe mounting distance from the hazard zone, enabling downsized machine layouts.

2. Automated Material Infeed and Outfeed Chutes

Securing conveyor ports where products continuously pass through a hazard boundary. Utilizing the built-in floating or fixed blanking functions, specified beam paths are bypassed for moving workpieces without stopping production.

Problem Solved

Prevents false safety trips and subsequent machine downtime during normal material flow while maintaining operator safety.

3. Multi-Machine Electronics Assembly Areas

Guarding contiguous semi-automatic workstation benches where adjacent machines use optical sensors. The built-in ELCA function automatically shifts scanning frequencies to ignore neighboring light curtains.

Problem Solved

Prevents optical crosstalk and erratic system shutdowns caused by extraneous light sources or adjacent safety units.
