SICK T4000-DNA15P Safety Interlock Switch Cordset

The SICK T4000-DNA15P is a non-contact safety interlock switch from the T4000 Standard family that uses RFID-coded actuators for tamper-resistant safety monitoring. Supplied as a 15 meter cordset (part number 6012146) with a 4.6 mm cable, PVC jacket, and copper conductors of 0.25 mm², it is designed to be paired with a compatible T4000 evaluation unit to deliver uniquely coded safety signals. The device’s sensing principle is RFID, with an assured switch-on distance Sao specified at 5 mm (10 mm in certain configurations) and a switch-off distance Sar of 23 mm (32 mm in some configurations); it supports five actuation directions and requires a minimum dwell time of at least 0.5 s for safe operation. The housing is glass-fiber reinforced thermoplastic (Fortron) and the overall dimensions are 25 mm W × 42 mm H × 12 mm D with an approximate weight of 0.53 kg. Cables are rated for fixed installation with bend radii greater than 5 × cable diameter (and more than 10 × for moving installations). The interlock cordset is rated IP67, suitable for harsh industrial environments, and is designed for machine safeguarding applications where a coded safety interlock must be integrated into a safety circuit. This model is commonly used in safety setups requiring a uniquely coded interlock pairing, with compatibility noted for specific SICK evaluation units such as the T4000-1RBA01.
