59150 Flange Mount Sensor + 57150 Actuator
Description
The 59150 is a flange mounting reed sensor 28.57mm x 19.05mm x 6.35mm
(1.125” x 0.750” x 0.250”) with a choice of normally open, normally open high
voltage, normally closed or changeover contacts. Its case design enables screw
or adhesive mounting and the wires exit from top right hand side. It is also
available with left hand exit - see 59145 Series. It is capable of switching up to
265Vac/300Vdc at 10VA. The 59150 functions best with the matching
actuator 57150-000.

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.
