Why Choose the Pizzato FR 20A1-A Position Switch?
The Pizzato FR 20A1-A is a robust industrial position switch with short piston plunger and external gasket designed for reliable mechanical position detection in machinery and automation systems. As part of the established Pizzato FR series, it combines a durable technopolymer enclosure with a compact plunger actuator for dependable switching in demanding industrial applications.
This position switch uses a short piston plunger with external protective gasket, making it suitable for applications where machine components directly operate the switch through linear movement. Its 1NO + 2NC slow-action contact block provides three contacts for signalling and control, while positive-opening operation supports use in appropriate safety-related machinery applications.
With an IP67 protection rating according to EN 60529 and a PG13.5 threaded cable entry, the FR 20A1-A provides a compact and durable solution for industrial machinery. The external gasket helps protect the plunger mechanism from environmental contamination, supporting dependable operation in production equipment, material handling systems and automated machinery.

Reliable Plunger-Operated Position Detection
Position switches such as the Pizzato FR 20A1-A provide an electrical switching signal when a moving machine component physically depresses the piston plunger. This allows industrial control systems to detect position, movement or end-of-travel conditions and use the resulting signal for machine sequencing, monitoring and control.
The short piston plunger is particularly suitable for direct linear actuation where a cam, carriage, stop or other moving component approaches the switch. Combined with the external gasket, 1NO + 2NC slow-action contacts, positive-opening functionality and IP67 enclosure, the FR 20A1-A provides dependable position detection for industrial machinery.
Typical Applications
- Industrial machinery position detection.
- Machine safety and control circuits.
- Automated production and assembly equipment.
- Conveyors and material handling systems.
- Packaging and processing machinery.
- Mechanical travel and end-position monitoring.
- Direct cam and carriage position detection.
- OEM machinery and industrial automation systems.
