Heidenhain ST1287 Linear Measuring Device 511401-01 Measuring Probe ST 1287 Linear Measuring Probe

The Heidenhain ST 1287 Specto Measuring Probe, part number 511401-01, is a highly precise, pneumatically actuated length measuring probe from Heidenhain in Germany. The ST 1287 was developed for use in measuring fixtures, automated measurement systems, and test stations, and offers an accuracy of ±1 μm over a travel of 12 mm. This makes it ideal for demanding industrial applications. The right-angled cable outlet and the ball-jointed plunger ensure a low-friction measuring process and consistent repeatability. The device outputs a 1 Vpp sine signal with a grating period of 20 μm and has a reference mark for indexing. It offers robust connections (15-pin D-sub connector), IP64 protection, and a rugged temperature range - well-suited for precision measurement technology in production environments.This sensor outputs a smooth 1 Vpp sine signal, enabling high-resolution interpolation for precise feedback. The signal interface is provided via a 12-pin D-sub connector or an M23 connection. The ST 1287 offers robust industrial durability, has IP64 (or even IP67 in some variants) protection, operates reliably between 10 °C and 40 °C, and weighs approximately 4050 g (without cable) for a compact installation. It contains a single reference mark, located 5 mm from the upper stop, to support precise positioning and repeatable zeroing. This measuring device is based on the proven SPECTO platform, is compatible with Heidenhain measuring devices (e.g., Metro or ND series), and can be easily integrated into metrology or CNC in-process measurement systems.
