Hall Effect Sensor Coded Switch

July 18, 2013
Elma Electronic Inc. introduces the X4, the first in a family of new rugged switches based on the latest Hall Effect sensor coding technology.

The X4 from Elma Electronic Inc. is the first in a family of new rugged switches based on the latest Hall Effect sensor coding technology. Hall Effect sensing technology offers enhanced reliability and performance where conventional switches would not survive, such as in the presence of dust and/or vibrationProducts that could benefit from this new switch technology would be any device required to withstand harsh environments as found in the construction, transportation, industrial and defense industries.

Elma's X4 Series  features a 5-bit Gray code output with 12 or 24 positions for exceptional resolution as well as parallel analog and PWM outputs. The X4 is available in two indexing angles, either 30 or 15 degrees. Selectable switching torque, from 1.5 N cm to 20 N cm, is available and the indexing mechanism itself boasts a life of up to 100,000 switching cycles.

Designed to meet IP68 (with optional sealing), the new X4 switch features high-quality construction including a stainless steel shaft and zinc housing, making it suitable for use in high humidity and salt atmosphere environments. It is also resistant against a variety of other environmental stress factors like shaft load, shock, vibration, water pressure and fire.

The rugged design enables the X4 switch to operate in a wide range of temperatures (-30°C to +85°C). The new switch also meets MIL-STD-202G and MIL-STD-810F for humidity.

Along with a push-button switch option, the X4 Series  can be customized with different shaft styles, connectors and cabling as well as electrical interfacing such as CANbus, SPI and I²C.

This family of X4 Series Hall Effect sensor coded switches includes versions for audio applications, including one for audio attenuation. Pricing for the X4 Series Switch starts at $20 per unit. Delivery is eight weeks ARO with some samples available within one week.
