Otto IP68S Through Hole Thumbwheel Switch, Hall Effect, 3000000 Cycles Mechanical Life

Otto IP68S through hole thumbwheel switch model HTWM-1B12A22 is a compact Hall Effect proportional thumbwheel designed for robust industrial applications. Featuring a self-centre single axis actuator, the switch provides linear voltage output, enabling precise position sensing without mechanical wear.

This Thumbwheel Switch supports snap-in style mounting for quick installation into a 34.03 x 17.78 mm panel cut-out with a behind panel depth of only 24 mm, making it ideal for space-constrained environments.

Rated IP68S, the electronics are fully sealed against dust and water ingress, ensuring reliability in harsh and wet environments. Operating temperature ranges from -40°C up to 85°C with high EMI and RFI immunity for stable signal integrity.

The HTWM series offers four output configurations, including increasing or decreasing voltage from centre to full travel, and single or dual redundant outputs, enhancing safety and flexibility in control systems.

Mechanical life is rated at 3,000,000 cycles, supporting long service intervals and reduced maintenance costs. Pre-wired options use 450 mm long 18AWG cable with stripped ends, streamlining installation tasks.

The black bezel and wheel provide an ergonomic and aesthetic interface suitable for armrest, grip, and panel-mounted control applications across industrial automation, electrical control, and machinery systems.

The device features a self-centre single axis actuator that provides linear voltage output change. Snap-in mounting fits a 34.03 x 17.78mm panel cut-out with 24mm behind panel depth. Operates reliably between -40°C to 85°C with excellent EMI/RFI immunity.

Available with four output options including single or dual outputs per axis. Pre-wired versions come with 450mm 18AWG wires with stripped ends for easy installation. The black bezel and wheel design ensures ergonomic panel integration.

Ideal for use in armrest, grip, and panel applications requiring durable, contactless rotary sensing. Explore more high-quality industrial electrical switches and automation components at EnvMart to suit your specific application needs.
