SICK RE21 Series Safety Switch, IP67, 1NO 1NC Safety Contacts - RE21-SA84

This safety switch is a non-contact magnetic sensor designed to monitor guard positions in industrial environments. It operates with reed outputs and connects via a short cable with an M8 4-pin male connector, offering status indication through LEDs. The unit is housed in VISTAL® material and is intended for use where a compact, sealed interlock is required while the safety logic is handled by external circuitry.

Features and Benefits:

• IP67 enclosure protects against dust and water ingress
• 400mA contact current supports low-power safety circuits
• Switchable up to 230V AC for AC safety monitoring
• Operates between -30 to 60°C for broad ambient conditions
• Five actuation directions enable flexible mounting orientations

Applications

• Suitable for guarding on assembly-line access panels
• Ideal for integration with external safety logic units
• Used with metal actuators where magnetic sensing is required
• Can be used for machine perimeter interlocking in wet areas
• Used for monitoring removable covers on conveyor systems

What type of output does it provide?

It uses reed switch outputs providing one normally open and one normally closed contact for safety signalling.

How is the unit connected to a control system?

It connects via a 0.2m cable terminating in an M8 4-pin male connector with copper conductors.

Does the switch detect its own internal faults?

It has no internal fault detection

connected safety logic must perform fault monitoring.

What mechanical stresses can it withstand?

It meets vibration resistance of 10Hz to 55Hz with 1mm amplitude and shock resistance of 30g for 11ms.
