From Cynergy3, the SSF211 series and SSF212 series are horizontal float switches. They operate in liquids with Specific Gravity (SG) of 0.8 or above. These float switches are constructed from a reed switch and pivoted actuator magnet. SSF211 and SSF212 switches feature an N/C (normally closed) contact.

SSF211 float switches are designed for horizontal mounting within a tank. They are only suitable for applications where you have suitable access to the inside of the tank so that you can fit them. SSF212 float switches can be mounted from outside the tank and do not require access.

• While supplied with an N/O contact, you can easily configure this to N/C (normally closed) by inverting the switch by 180° when you mount it. Instead of the float moving in a downwards direction as standard, it would move in an upwards direction away from the main body of the switch.
• These float switches feature a compact design at only 47 mm long.
• The stem is constructed from SS304 stainless steel while the float is made from SS316 stainless steel. This ensures that these limit switches are suitable for use in the most rugged environments.
• All SSF211 float switches are fitted with a 1 m long 17/0.10 (AWG22) cable. They can be fitted internally via a 1/8” BSP thread.
• SSF212 float switches are fitted with a 1 m long 17/0.10 (AWG22) cable, plug and socket or M12 socket. This varies by model. They can be externally fitted via a 1/2” NPT thread.

Looking for a float switch that's suitable for use in harsh environments? This Sensata Cynergy3 float switch has a stem and float made of robust stainless steel material, making it highly durable and resistant to corrosion. The switch is simple to install as there's no need to access the inside of the tank – you can mount it horizontally via a 1/2-in NPT (National Pipe Thread) thread from the outside of the tank. For versatile use, you can change from normally open (NO) to normally closed (NC) operation by mounting the device with the orientation arrow pointing downwards, instead of in the upwards direction.

• Length of only 47 mm for use in compact setups
• Wide operating temperature range of -10°C to +120°C for use in a variety of demanding applications
• Cable length of 1 m for ease of connection

The switch is designed for resistive loads only. It's not suitable for use with inductive loads or applications where there's a significant inrush current.
