59630 Sensor with Integral Float Actuator
Description
The 59630 is a reed level sensor with integral float actuator and an M8 x
1.25mm pitch thread with a choice of normally open, normally open high voltage,
normally closed or change over contacts. It is capable of switching up to
265Vac/300Vdc at 10VA. It is ideally suited to liquid and air conditioning
condensate and industrial process control applications.
Features
• Sensor with integral blown
polypropylene float, with integral
magnet
• Sensor operates when float rises
from end stop position
Choice of contacts
• Choice of connector and cable
length options
• RoHS Compliant
Benefits
• Hermetically sealed, magnetically
operated contacts continue to
operate long after optical and other
technologies fail due to
contamination
No standby power required
• Simple installation with M8 thread
and nut
Applications
• Liquid level control
• Air conditioning systems

Notes:
1. Contact rating - Product of the switching voltage and current should never exceed the wattage rating. Contact Littelfuse for additional load/life information.
2. When switching inductive and/or capacitive loads, the effects of transient voltages and/or currents should be considered. Refer to Application Notes AN108A and AN107 for details.
3. Breakdown Voltage - per MIL-STD-202, Method 301.
4. Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load.
5. This resistance value is for 300mm wire length. Resistance varies based on wire length.
6. Operate (including bounce)/Release Time - per EIA/NARM RS-421-A, diode suppressed coil (Coil II).
7. Shock and Vibration - per EIA/NARM RS-421-A and MIL-STD-202.
8. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse.
Note:
Normally Open: contacts are open when float is down as shown in the De-activate
view. The contacts close when float is in upward position as shown on the left view.
Normally Closed: Contacts are closed when the float is in the down position.
The contacts open when float is in the upward position as shown in the left view.
