SICK FXL1 Safety Interlock Switch, Power, Vistal, Interlock

This safety interlock switch provides monitored locking for access points in industrial settings. It employs RFID sensing and a power-to-lock mechanism to prevent unauthorised opening while offering escape release capability. The unit is designed for integration into safety architectures with both cabinet-based and Flexi Loop diagnostics and connects via an 8‑pin M12 plug. It is suitable for environments requiring rugged protection and electrical safety outputs.

• SIL3 and PL e safety level supports high-risk applications
• 2 PNP semiconductor safety outputs limit output current to 100mA
• Power-to-lock concept permits controlled locking and escape release
• IP65, IP67, IP69K enclosure resists dust and high‑pressure washdowns
• Operating range -20°C to +55°C covers varied ambient conditions

• Suitable for guarded doors requiring locking and monitored release
• Ideal for machine safety chains with series diagnostics
• Used with safety relays and Flexi Compact controllers
• Can be used for hygienic wash‑down environments in production
• Suitable for installations needing coded RFID actuator identification

It provides two self‑monitoring semiconductor OSSD outputs implemented as PNP devices with cross‑circuit monitoring.

It runs from a 24V DC supply with an allowable range of 19.2V DC to 28.8V DC.

The unit uses an 8‑pin M12 plug connector with a stainless‑steel coupling nut and requires compatible M12 connection cables.

Response time is ≤150 MS, release time is ≤350 MS and risk time is 150 MS, with series connection adding 70 MS per additional device.

Mechanical life is rated at 1x10^6 switching cycles and the housing is manufactured from VISTAL® with stainless‑steel brackets and plug components.
