Float Sensor > 59630 

## 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 

## **Dimensions** 

Dimensions in mm (inch)

## **Benefits** 

   - No standby power required 

- Hermetically sealed, magnetically No standby power required operated contacts continue to • Simple installation with M8 thread operate long after optical and other and nut technologies fail due to contamination 

## **Applications** 

   - Industrial Process Control 

- 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. 

## **Activation** 

Using sensor with float magnet orientated is illustrated

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.
