SICK STR1 Safety Switch, RFID Actuator Included, Vistal

This safety switch is a non-contact RFID interlock designed to monitor guards and access points in industrial settings. It uses RFID sensing with a permanently coded actuator and provides dual safe semiconductor outputs alongside an auxiliary contact for diagnostics. The unit is supplied by a 24V DC source and features a Vistal housing suited to washdown and harsh environments, offering high ingress protection and a Compact form factor for confined installations.

• SIL3 safety integrity providing high functional safety levels
• Category 4 performance enabling highest risk reduction
• 100mA output current supporting low-power control circuits
• 40ms response time allowing Rapid safety signalling
• IP69K rating permitting high-pressure, high-temperature washdowns

• Used for machine guard RFID interlock on production lines
• Suitable for Compact safety switch installations in tight spaces
• Ideal for hygienic washdown environments requiring IP69K protection
• Used with safety controllers requiring dual OSSD outputs
• Can be used for access monitoring where a high coding level is required

It is fitted with a 3M five-core PVC cable with 5.5mm diameter and copper conductors suitable for fixed and moving installations.

On fault at least one semiconductor safety output is switched to the OFF state to signal a safe condition.

The operating temperature range is -30°C to +70°C for applicable serial number series

It resists vibration at 10Hz to 55Hz with 1mm amplitude and shock up to 30g for 11ms.

Assured switch-on distance for frontal approach is 10mm and switch-off distance is 25mm with three Active sensor surfaces and five actuation directions.
