Product description
Magnetic Contact Sensor 90142
The 90142 is a wireless magnetic contact sensor using a replaceable coin-cell supply. Its published details include a blue LED indicator, compact dimensions and an open-air range reference.
The magnetic contact sensor combines a coin-cell supply with RF transmission and a blue LED indicator. The published dimensions, standby current and temperature range support an initial check of mounting space and operating conditions. The product record states that the specified battery is included.
A contact-sensor installation also depends on the sensor and magnet arrangement and on the receiving system. Confirm the detection gap, mounting position, compatible receiver and pairing procedure before defining a complete solution. The open-air range is a radio reference, not a guarantee of performance through walls, and standby current alone is not a battery-life promise.
