1078749

Overview

SICK part number 1078749 corresponds to the WTB27-3P2461, a two-wire safety light curtain designed for personnel protection. This device features a resolution of 30 mm and a protective height of 540 mm. It operates with a response time of 15 ms and utilizes PNP switching outputs. The unit is rated IP67 for dust and water resistance, ensuring reliable operation in industrial environments. It supports standard safety categories including PL e and Category 4 according to EN ISO 13849-1.

Feature Summary

• Two-wire technology simplifies wiring by combining power supply and signal transmission on a single pair of conductors.
• High-resolution 30 mm sensing capability ensures precise detection of human body parts for enhanced personnel safety.
• Robust IP67 housing provides complete protection against dust ingress and temporary water immersion.

Applications

• Personnel protection at press brakes and stamping machines
• Safety guarding for injection molding equipment
• Protection zones around automated assembly stations

Procurement Notes

Verify that the specific order number 1078749 matches the required resolution and protective height for your application. Confirm compatibility with existing control systems regarding voltage levels and output types. Ensure all safety regulations relevant to your region are met before installation.

Selection Notes

Choose this model when space constraints require a compact solution without compromising safety integrity. The two-wire design reduces cabling complexity compared to four-wire alternatives. Consider the 30 mm resolution as sufficient for general personnel protection where higher precision is not mandated by risk assessment.
