Light curtains are an effective form of safeguarding for automated machinery. The SF4B-H24G-01(V2) is a model of light curtain specifically designed for a variety of industrial applications. In this article we will explore the application field and working principles of the SF4B-H24G-01(V2).

Application Field

The SF4B-H24G-01(V2) is best suited for automated machinery with a maximum speed of 25 m per second. It is compliant with ISO13849-1 type 3 and offers protection up to PL e with a SIL3 rating. It has a range of up to 24m and an increasing range of up to 36m with extended application. Its narrow beam width of 9mm makes it a great choice for high-speed applications. The SF4B-H24G-01(V2) also supports type 4 electric interlock and emergency stop. It is a type 4 device with a Sensor Failure Detection and Drift Compensation (SFDC) function, and its optional functions include an area monitor, external switch, and an ON/OFF skip.

Working Principle

The SF4B-H24G-01(V2) is a type 4 light curtain that works by emitting infrared beams at a 24mm pitch. These beams detect any intrusions in the protected area and are then reflected back to a receiving/emitting unit. The device can be set up as a point-to-point unit or an array, depending on the application. The SF4B-H24G-01(V2) is also equipped with an adjustable response time of up to 30mS, which allows it to adjust to the speed of the application. It also features a Sensor Failure Detection and Drift Compensation (SFDC) function which monitors the status of the beams, compensates for drift caused by aging, and detects any potential failures.

In addition to detecting intrusions, the SF4B-H24G-01(V2) can also be used as an area monitor. The area moni­tor function allows the device to detect any foreign objects or objects that are out of place in the protected area. It can also be used with an external switch to control other functions, as well as an ON/OFF skip feature which can be used to bypass the light curtain in certain applications.

Conclusion

The SF4B-H24G-01(V2) is an effective form of light curtain safeguarding for automated machinery. It is well suited for high-speed applications and offers protection up to PL e with a SIL3 rating. It features a range of up to 24m and an adjustable response time of up to 30mS. It also has a range of optional features, such as an area monitor, external switch, and an ON/OFF skip. All these features make the SF4B-H24G-01(V2) an ideal choice for keeping people and machinery safe.
