Float switch S/S external, 1/2 NPT

Horizontal

Ensure that the level of fluid in your tank is automatically regulated with this Sensata Cynergy3 float switch. The switch setting is adjustable, so you can set it to NC (normally closed) or NO (normally opened) function by simply inverting the float switch by 180°. You can use this float switch to activate alarms or indicators that notify you when the liquid in the tank is too low or too high. As it can be fitted from the outside of the tank, this is a smart choice in situations where you can't access the inside.

Features and Benefits

• Tinned copper cable for reliable conductivity
• Stainless-steel body for resistance to rust, even in humid environments
• Compact size of just 47 mm for use in tight spaces
• XLPE (cross-linked polyethylene) cable sheath for protection against extreme temperatures

How do I install this float switch?

The switch has a 1/2-in NPT (National Pipe Thread) thread that you can simply screw into place on the outside of your tank. The fixing nut ensures that the switch remains securely in place.

Cynergy3 SSF211 and SSF212 Horizontal Float Switches

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.

Features & Benefits

• 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.
