59135 High Temperature Flange Mount Sensor + 57135 Actuator

Description

The 59135 is a high temperature flange mounting reed sensor 28.57mm x

19.05mm x 6.35mm (1.125” x 0.750” x 0.259”) with a choice of normally open,

normally open high voltage, normally closed or changeover contacts. It’s case

design enables screw or adhesive mounting. It is rated for operation up to 150°C.

It is capable of switching up to 265Vac/300Vdc at 10VA. The 59135 functions

best with the matching actuator 57135-000.

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 11.81mm 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.

8. For custom modifications to the wire length or size, or adding a special connector, please contact Littelfuse.
