New low-cost cable extension position sensor series now available with incremental encoder

The Celesco SR1 range now includes encoder, voltage divider and user programmable 4..20 mA and VDC versions with electrical and mechanical flexibility that allows users to select a single low-cost product solution across many general purpose applications for cable extension based position sensing. The 'one-size-fits-all' SR1 range can eliminate the customers’ need to specify and purchase multiple stroke ranges and offer benefits of simplified stock and lower unit cost.

Specific to the new SR1E encoder version, a 5...30 VDC push-pull driver covers a wide choice of supply voltages and electrical connection is via an M12 – 4-pin connector with mating plug supplied and 4 m cable sets are available on request.

The maximum velocity for the sensor is 2 m/sec with maximum acceleration at 10 g with an operating temperature from -20ºC to +85ºC. The overall accuracy for SR1E is +/- 0.1% F.S. and repeatability to +/- 0.05% F.S. Custom encoder resolutions are also available on request.

As with all string pot or cable extension sensors from Celesco, installation is very straightforward with no critical alignment required. The nylon coated stainless steel cable is fully spring loaded, is easily attached to the object under motion and fully retracts into the body of the SR1E ensuring a compact installation envelope of around 200 x 120 x 100 mm (w x h x d).
