Overview
The Sick T40-E0101K (part number 6035041) is a non-contact transponder safety switch designed for machinery protection and safety interlock applications. Part of SICK’s T4000 Direct series, this switch provides PLe Cat4 Type 4 rated safety performance with universal actuator coding per EN ISO 14119. The sensor-only design (actuator sold separately) enables flexible machine integration across five actuation directions.
Key Features
- Non-contact operation: Eliminates wear from mechanical contacts, improving reliability and uptime.
- Two OSSD safety outputs: Dual semiconductor outputs for safety-critical control circuits.
- PLe Cat4 Type 4 rated: Meets EN ISO 13849-1 performance level e and IEC 61508 SIL 3 requirements.
- Universal actuator coding: Works with multiple T4000-1KBA, T4000-1KBQ, and T4000-1KBR actuators.
- M12 connector: 8-pin M12 interface with 0.2M pre-equipped cable for plug-and-play integration.
- IP67 rated: Sealed plastic PBT housing for washdown and harsh industrial environments.
