PANASONIC SF4B-H12C / H96C — Safety Light Curtains
Panasonic SF4B-H□C: compact Type 4 safety light curtain, PL e / SIL 3, ø25 mm, 0.3–7 m, 263.4–1,943.4 mm, OFF 14 ms.
Status: In production
Brand: Panasonic
Product: Compact Type 4 safety light curtain (hand protection, 25 mm)
Safety level: Type 4, Category 4, PL e, SIL 3
Minimum sensing object: ø25 mm (20 mm beam pitch)
Operating range: 0.3–7 m
Protective height: 263.4–1,943.4 mm (12–96 beams)
Response time (ON→OFF): 14 ms or less
The Panasonic SF4B-H□C is the hand protection type of the SF4B-C series: it detects opaque objects of ø25 mm with a 20 mm beam pitch over an operating range of 0.3–7 m. It is Type 4 to IEC 61496-1/2, Category 4, PL e to ISO 13849-1:2015 and SIL 3 to IEC 61508. A metal inner frame inside the plastic body allows protective heights up to 1,943.4 mm across 15 models. The manufacturer states that the plastic body is 45 % lighter than the previous aluminium-enclosure model.
Two versions are available: the cable type with a 5 m cable (SF4B-□C, 8-core) and the pigtailed type with muting function and a 0.5 m connector cable (SF4B-□CA-J05, 12-core, with large multi-purpose indicator). OSSD 1 and OSSD 2 are switchable between PNP and NPN, max. 200 mA. OFF response is 14 ms or less and ON response 80–90 ms. The ELCA function reduces mutual interference without an interference prevention line. External device monitoring, interlock and emission halt are built in; fixed and floating blanking are set with the SFB-HC handy-controller.

Is this light curtain right for your machine?
Share the width and height of the opening to be guarded, the required resolution (finger/hand/body), the machine stopping time, the required performance level (PL) and your safety controller; let’s define the right model, safety distance and wiring together.
All product specifications are subject to change without notice. Validation of the safety function and the risk assessment remain the responsibility of the machine builder.
