Dual Axis Tilt Switch With Adjustable Threshold

Product catalog summary

Specifications
The ETS Dual Axis Tilt Switch features adjustable thresholds with part numbers ETS 1-4, ETS 4-11.5, ETS 10-25, and ETS 20-50. The switching range varies from 1-4° to 20-50°, with adjustment steps from 0.2° to 2°. Switching accuracy ranges from ±0.1° to ±1°, and hysteresis is between 0.2° and 2°. The device operates at a bandwidth of 0.25Hz, requires a power supply of 7-35Vdc, and has a maximum current of 40mA. It supports a switching capacity of 220Vdc, 250Vac, and 60W max. The dimensions are 65x60x40mm for the housing or 50x35mm for the PCB, with a temperature range of -20 to 65°C and IP67 sealing for housed types.

Part Numbering
There are three main types: single axis, dual axis, and omni-directional, each with four versions for different switching angles. The dual axis version allows individual adjustment for X and Y axes, while the single axis monitors only the X axis. The omni-directional version combines both axes to calculate the tilt angle. Once the threshold is reached, the relay operates, closing the switch contacts for alarms or system interfacing.

Description
The tilt switch offers single, dual, or omni-directional sensing with adjustable thresholds from 1 to 50°. It includes a 'ZERO' button for post-installation calibration, features small size and low power consumption, and has no moving parts for long life and minimal servicing. Customization is available for various applications.

Applications
Applications include bank angle warning systems for ride-on mowers, safety cut-outs for cranes, tilt warning systems for platforms, rollover warnings for agricultural vehicles, and safety cut-outs for telescopic and scissor lift platforms.

Wiring Information
The wiring involves a terminal block with specific functions: Blue for Switch Common, Green for Switch NO, Grey for Switch NC, Brown for +Ve Supply, and Black for GND.

Dual Axis Tilt Switch With Adjustable Threshold-1

level developments ETS : Dual Axis Tilt Switch With Adjustable Threshold Description There are three main types, single axis, dual axis and omni-directional. For each of these types there are four versions to cover a variety of switching angles. The exact switching angle can be adjusted with the pcb mounted rotary switches. With the dual axis version the tilt thresh-old (the trip angle) can be adjusted individually for the X and Y axis. With the single axis version, only the X axis is monitored, and with the omni-directional version, the measurement of both axis is combined to calculate the resultant tilt angle. Once the tilt thresh-old is reached the relay operates and the switch contacts are closed. This can be used to sound an alarm, switch on a warning light, or interface directly to a machines control system. Single, dual or omni-directional tilt sensing Adjustable switching threshold from 1 to 50° 'ZERO' button to set zero after installation Small size and low power consumption.
