Reed Sensor **Datasheet** 

## **59025 Reed Sensor** 

## **Description** 

The 59025 Reed Sensor is a small cylindrical reed sensor, 25.4 mm (L) x 6.22 mm (Dia.) (1.00” x 0.245”), with a choice of normally open, normally closed or change-over contacts. It is capable of switching up to 265 Vac/300 Vdc at 10 VA. The 59025 Reed Sensor is  available with a range of sensitivity and cable length options. It is well suited for use in a wide range of industrial, appliances, or IoT proximity sensing applications. 

It functions best with the 57025 actuator. 

## **Features & Benefits** 

## **Additional Information** 

   - Can operate through non-ferrous materials (for example, wood, plastic, or aluminum) 

- Non-contact switching solution for wet & harsh environments 

- No leakage current in ‘open’ state−ideal for battery■ Available in select sensitivities powered IoT applications (operating distances) 

   - Standard cable configurations; customization options available 

- Helps implement efficient proximity/access and energy management systems 

- Compact size and easy ■ UL Recognized per UL 508 installation and effective and CSA C22.2 No. 14. concealment in many applications

## **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. Leakage current is less than 0.1 mA for 60 seconds. 

**4.** Electrical Load Life Expectancy - Contact Littelfuse with voltage, current values along with type of load. 

**5.** This resistance value is for 300 mm wire length. Resistance changes when wire lengthens. 

**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.
