TR4 Direct – Product Overview

Safety switches - TR4 Direct is part of SICK's industrial safety switches portfolio. The TR4 Direct family is designed for professional machine, production and process environments where dependable sensing, safety monitoring, measurement or motion feedback is required. This product entry is written as customer-facing ecommerce content and keeps the technical identity tied to the SICK family documentation rather than introducing unsupported specifications.

Core Function and Operating Principle

The core function of the TR4 Direct family is to provide a defined, repeatable signal to the automation system. The published source describes the product around its operating principle and configuration structure, while the technical table below records the values that can be stated directly from the SICK documentation. Where a parameter is configuration-dependent, that dependency is retained rather than replaced with an assumed single value.

The documented application strengths of this family include “RFID-based non-contact safety switching” “PL e / SIL3 safety architecture” “Two OSSD safe outputs” “Response range up to 25 mm”. These characteristics make the range relevant where repeatable machine signals, controlled sensing, dependable safeguarding, process measurement or motion feedback are required.

Technical Performance

The SICK documentation publishes Safety level: PL e / SIL3; Safe outputs: 2 OSSD; Response range: Up to 25 mm; Series connection: Up to 30 devices; Enclosure: IP69K on supported types. These values define the engineering envelope described by the source material and should be read together with the selected ordering code where the family contains multiple configurations.

The SICK documentation publishes Connection: M12, 8-pin / 5-pin or cable depending type. These values define the engineering envelope described by the source material and should be read together with the selected ordering code where the family contains multiple configurations.

Electrical, Interface and Connection Details

The published SICK configuration defines the electrical and communication architecture for TR4 Direct. Depending on the documented type, this can include the stated supply, switching outputs, analog signals, safety outputs, industrial communications, connectors or other interfaces. The specification table keeps those source values explicit so they can be checked during engineering and purchasing.

Mechanical and Environmental Design

The family is intended for industrial installation, with the source documentation defining its housing, enclosure, temperature, mechanical and connection characteristics where these are published. No additional material or environmental ratings have been added where SICK does not publish them for the family row.

Configuration, Commissioning and Integration

For system integration, selection should follow the required sensing or safety range, output behaviour, connection, mounting arrangement and environmental conditions. The SICK documentation is structured around ordering variants, so the exact part number should be checked before purchase or installation. This is particularly important where the family offers multiple electrical interfaces, optical arrangements, resolutions, safety functions or housing options.

Commissioning should use the SICK installation and configuration documentation for the selected ordering code. Confirm mechanical clearances, electrical compatibility, required accessories, safety architecture and application-specific parameters before putting the device into service. For safety-related products, the final system design must follow the applicable SICK documentation and the relevant safety standards for the complete machine.

Typical Industrial Applications

The published SICK application scope for this family includes Guard-door monitoring, Machine guarding, Hygienic or demanding environments. The appropriate use depends on the actual machine architecture, target object or medium, required operating range and selected variant. The family is particularly suited to engineering-led procurement where exact product configuration matters.
