Compact solid-state switch with 9.8 ft three-wire lead and LED indicator

SPEEDAIRE

SPEEDAIRE Solid State Switch PNP 24VDC 9.8 ft lead

SKU CH-SW1Z-KTK8W

PNP solid-state switch with 9.8 ft lead, 24 V DC operation, 40 mA max current and LED indicator for air cylinders and grippers

  • PNP output simplifies wiring for 24 V DC systems
  • 8 ft pre-wired lead reaches distant mounting points
  • 40 mA max switching current handles low-power logic loads
  • LED indicator confirms switch status at a glance
  • Operates reliably from 14 °F to 140 °F

Solid-State Switch for Pneumatic Actuators

This SMC solid-state switch mounts directly on compatible air cylinders and slide tables to provide position feedback. It operates on 24 V DC with a PNP output and a maximum switching current of 40 mA. The unit comes pre-wired with a 9.8 ft lead for straightforward installation. It suits automation technicians who need reliable end-of-stroke detection on guided compact cylinders, rotary vane actuators or parallel grippers.

Sustained Operation Within Rated Limits

The switch is rated for continuous use between 14 and 140 degrees Fahrenheit, maintaining its 40 mA switching capacity throughout that range. Its composite enclosure and solid-state design contain no moving contacts, so repeatability does not degrade with cycle count. An integrated LED gives immediate visual confirmation of the switched state during extended production runs.

Compatibility Checks Before Ordering

Verify that the target actuator is listed among the supported bore-diameter air slide tables, extruded guided compact cylinders, rack-and-pinion rotary vane tables or repairable aluminum cylinders. Confirm the control system accepts a 24 V DC PNP signal with three-wire wiring. Ensure the 9.8 ft lead reaches the termination point without splicing.

Questions about this item

Does the 24 V DC solid-state switch generate noticeable heat when it runs continuously?

It draws a maximum of 40 mA at 24 V DC, so heat output is minimal during all-day operation.

What pneumatic cylinder or actuator must I already have for this switch to mount and function?

It fits bore-diameter air slide tables, extruded guided compact air cylinders, guided air slide tables, rack-and-pinion rotary vane table actuators, parallel linear guide air grippers, and repairable switched single- or double-acting aluminum air cylinders.

Will the 9.8 ft pre-wired lead and PNP output work with my existing 24 V DC relay board?

Yes — the 3-wire 9.8 ft lead provides a PNP signal at 24 V DC, compatible with standard 24 V DC relay or PLC inputs.
