- Resists Oils and Coolants
- The GKM features a simple shape and structure, and yet provides IP67 protection and oil resistance.
- The protective structure eliminates the need for screws to hold a cover, so there are no worries about loose screws leading to liquid penetration.
- And the model number is laser-marked on the housing so it's always readable when the time comes to order maintenance parts.
- The compact, easy-to-use GKM with built-in amplifier is ideal for oily environments
