Overview

Fully Potted Limit Switches HDLS Non Plug-in: Low Temperature Version; Side Rotary; 1NC 1NO SPDT Snap Action; 12-foot Cable.The MICRO SWITCH fully potted HDLS provides an extra degree of protection in harsh environments by sealing the basic switch cavity with epoxy. These switches are the same as the non plug-in HDLS except that the entire switch cavity is filled with epoxy in addition to the conduit entrance, and the switches are preleaded, either with cable or connectors. The MICRO SWITCH harsh-duty limit switch also requires no adjustment over the life of the switch and provides an all metal drive train, superior sealing which keeps the shaft moving freely, twin fluorocarbon shaft seals, superior corrosion resistance, type 303 stainless steel shaft, anti-corrosion phosphate sealed epoxy finish and a valuable trouble shooting tool - 120 Vac neon or 24 V LED indicators available. The replacement head part number of the switch is metal stamped, so it won't wash off. It also provides a wide variety of operating heads, fluorocarbon diaphragm seal - which eliminates fluid infiltration, epoxied construction, zinc diecast housing, head and body, an additional body seal, fluorocarbon sealed cover and high compression ridge and your choice of termination options The MICRO SWITCHharsh-duty limit switch exceeds NEMA 6P because machine processes and their associated fluids demand more than the standard NEMA 6P switch provides. The switch meets the environmental challenges found in actual automotive production facilities and food and beverage lines. The MICRO SWITCH harsh-duty limit switch is made for environments that surpass NEMA 6P test criteria.
