MITI-7 7mm Ultra-Miniature Reed Switch

RoHS

Description

The MITI-7 ultra-miniature reed switch is a normally open switch with a 7mm x

1.8mm (0.276” x 0.071”) glass envelope, which is capable of switching 170Vdc at

10W. It has a sensitivity range of 6-20 AT. It has a high insulation resistance of

10⁹ohms minimum and low contact resistance of less than 150 milliohms.

The MITI-7 is also available in a surface mount version, that is, MISM-7.

Features

• Ultra-miniature, normally

open switch

• Available sensitivity range 6-20 AT

• Capable of switching 170Vdc or

0.25A at up to 10W

Benefits

• Zero operating power required for

contact closure

• Excellent for switching micro-

controller logic level loads

• RoHS Compliant

• Hermetically sealed switch contacts

are not affected by and have no

effect on their external environment

• Very low space requirement

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

4. Breakdown Voltage - per MIL-STD-202, Method 301.

5. Storage Temperature - Long time exposure at elevated temperature may degrade solderability of the leads.
