1136783

Overview

The SICK part number 1136783 is a configurable switch element belonging to the ES21 series. It functions as an auxiliary contact block designed for integration with compatible safety switches. The component features a single-pole, normally-closed (SPST-NC) circuit configuration. It utilizes screw terminals for electrical connection and requires a specific switch housing for proper installation. This auxiliary module expands the signaling capabilities of the primary safety device within industrial control systems.

Feature Summary

• Provides an additional normally-closed contact point for safety circuit monitoring
• Designed for modular expansion of existing safety switch housings
• Utilizes screw terminal connections for secure wiring

Applications

• Expansion of safety interlock circuits in machinery
• Integration with SICK ES21 safety switch series
• Industrial equipment guarding systems requiring auxiliary status feedback

Procurement Notes

Verify that the target application utilizes a compatible SICK ES21 safety switch housing, as this unit is an auxiliary component and not a standalone device. Confirm the requirement for a single-pole, normally-closed contact logic matches the system design. Ensure the mounting environment supports the mechanical specifications of the ES21 series accessories. Cross-reference the manufacturer's documentation for the specific list of compatible switch models to guarantee physical and electrical compatibility before procurement.

Selection Notes

Select this component only when an existing safety switch setup requires an additional normally-closed signal output. It is intended for use with the ES21 series safety switches. Do not select this item if a complete safety switch assembly is required, as it serves strictly as an add-on contact block. Verify that the control system can accommodate the expanded wiring provided by the screw terminal interface.

Part Context

This part belongs to the SICK ES21 product family, which consists of safety switches for industrial applications. The ES21 series is designed for machine guarding and access control. Part 1136783 specifically serves as an accessory to enhance the functionality of the main switch units by providing extra contact points for system integration.

Replacement Considerations

Compatible replacement parts include other auxiliary contact blocks from the SICK ES21 series, such as part number 6036136. Ensure any substitute maintains the SPST-NC configuration and screw terminal interface to preserve system integrity.
