Built on the proven performance of Canfield Connector’s widely used 8000 series, the 8A series introduces a fully molded, encapsulated housing that enhances protection in demanding environments while maintaining consistent sensing results. This updated design provides a cost-effective solution without sacrificing the performance engineers rely on in pneumatic sensing applications.

The fully molded construction improves environmental protection and insulation, making it well-suited for washdown environments and applications exposed to moisture or contaminants. By eliminating potential ingress points and reinforcing the housing, the design supports long-term durability and consistent operation in real-world conditions.

The 8A series also features an improved mounting design that reduces physical stress on the sensor during installation. Integrated mounting elements help ensure a secure fit across a range of round and tie-rod cylinder applications while supporting long-term reliability.

“With the 8A series, we wanted to take the proven performance of our 8000 series and make it even more durable and cost-effective,” said Todd Harmon, Vice President of Canfield Industries. “The fully molded design gives customers a better solution for tough environments without adding complexity.”

The sensor is intended for OEMs monitoring the position of pneumatic cylinders and grippers in applications such as product selection, press-fitting, riveting and ultrasonic welding. By sensing the magnetic piston, it transmits cylinder position to the PLC with repetition accuracy of 0.2 mm.

The SDAC-MHS is available in 20 mm and 30 mm sizes to match common stroke lengths used in Festo grippers and compact cylinders. The sensor detects the full piston stroke and end positions without extending beyond the cylinder body, which supports use in space-constrained installations. In addition to analog position feedback, the SDAC-MHS includes two programmable digital switching outputs, allowing one sensor to replace two conventional cylinder switches.

The SDAC-MHS sensor combines analog current output, digital switching outputs and IO-Link communication in a single device. In standard wiring mode, it provides continuous analog position feedback and one programmable digital switching output that can be set as normally open, normally closed, a window comparator or a hysteresis comparator. With IO-Link, the sensor provides three additional switching outputs and allows parameters to be configured through a graphical interface.

Key specifications of the SDAC-MHS include:

• Sensing ranges: ~20 mm (analog variant) and ~30 mm (IO-Link variant)
• Repetition accuracy: 0.2 mm
• Linearity error: ±2 mm
• Resolution: ~0.05 mm (analog) / ~0.012 mm (IO-Link)
• Analog output: 0–10 V
• Operating voltage: DC 10–30 V
• Mounting: Inserted in the C-slot on the gripper or cylinder
• Protection classes: IP65, IP68
• Port: 30 cm cable with M8, 4-pin connector

These switches are manufactured specifically to fit into extruded or machined 1/4-inch 60-degree dovetail slots. They are superior to reed switches because they utilize solid-state technology with no moving parts for a longer life. They are available in PNP or NPN logic, with a normally open output, and a flying lead pigtail or a 3-pin M8 electrical connection with a 90-degree cable exit.

The new NITRA CPS9E cylinder position switches start at $20.00 and come with a 1-year warranty.
